https://x.com/claudeai/status/2023817132581208353 [video] I see a big focus on computer use - you can tell they think there is a lot of value there and in truth it may be as big as coding if they convincingly pull it off. However I am still mystified by the safety aspect. They say the model has greatly improved resistance. But their own safety evaluation says 8% of the time their automated adversarial system was able to one-shot a successful injection takeover even with safeguards in place and extended thinking, and 50% (!!) of the time if given unbounded attempts. That seems wildly unacceptable - this tech is just a non-starter unless I'm misunderstanding this. [1] https://www-cdn.anthropic.com/78073f739564e986ff3e28522761a7... Isn't "computer use" just interaction with a shell-like environment, which is routine for current agents? Does it matter? Really? I can type awful stuff into a word processor. That's my fault, not the programs. So if I can trick an LLM into saying awful stuff, whose fault is that? It is also just a tool... I always grew up hearing “competition is good for the consumer.” But I never really internalized how good fierce battles for market share are. The amount of competition in a space is directly proportional to how good the results are for consumers. Remember when GPT-2 was “too dangerous to release” in 2019? That could have still been the state in 2026 if they didn’t YOLO it and ship ChatGPT to kick off this whole race. I was just thinking earlier today how in an alternate universe, probably not too far removed from our own, Google has a monopoly on transformers and we are all stuck with a single GPT-3.5 level model, and Google has a GPT-4o model behind the scenes that it is terrified to release (but using heavily internally). They didn't YOLO ChatGPT. There were more than a few iterations of GPT-3 over a few years which were actually overmoderated, then they released a research preview named ChatGPT (that was barely functional compared to modern standards) that got traction outside the tech community because it was free, and so the pivot ensued. I also remember when the playstation 2 required an export control license because it's 1GFLOP of compute was considered dangerous that was also brilliant marketing That's rewriting history. What they said at the time: > Nearly a year ago we wrote in the OpenAI Charter : “we expect that safety and security concerns will reduce our traditional publishing in the future, while increasing the importance of sharing safety, policy, and standards research,” and we see this current work as potentially representing the early beginnings of such concerns, which we expect may grow over time. This decision, as well as our discussion of it, is an experiment: while we are not sure that it is the right decision today, we believe that the AI community will eventually need to tackle the issue of publication norms in a thoughtful way in certain research areas. -- https://openai.com/index/better-language-models/ Then over the next few months they released increasingly large models, with the full model public in November 2019 https://openai.com/index/gpt-2-1-5b-release/ , well before ChatGPT. > Due to our concerns about malicious applications of the technology, we are not releasing the trained model. As an experiment in responsible disclosure, we are instead releasing a much smaller model for researchers to experiment with, as well as a technical paper. I wouldn't call it rewriting history to say they initially considered GPT-2 too dangerous to be released. If they'd applied this approach to subsequent models rather than making them available via ChatGPT and an API, it's conceivable that LLMs would be 3-5 years behind where they currently are in the development cycle. They said: > Due to concerns about large language models being used to generate deceptive, biased, or abusive language at scale, we are only releasing a much smaller version of GPT‑2 along with sampling code (opens in a new window). "Too dangerous to release" is accurate. There's no rewriting of history. Well, and it's being used to generate deceptive, biased, or abusive language at scale. But they're not concerned anymore. Unfortunately, people naively assume all markets behave like this, even when the market, in reality, is not set up for full competition (due to monopolies, monopsonies, informational asymmetry, etc). The real interesting part is how often you see people on HN deny this. People have been saying the token cost will 10x, or AI companies are intentionally making their models worse to trick you to consume more tokens. As if making a better model isn't not the most cutting-throat competition (probably the most competitive market in the human history) right now. Only until the music stops. Racing to give away the most stuff for free can only last so long. Eventually you run out of other people’s money. I mean enshittification has not begun quite yet. Everyone is still raising capital so current investors can pass the bag to the next set. Soon as the money runs out monetization will overtake valuation as top priority. Then suddenly when you ask any of these models “how do I make chocolate chip cookies?” you will get something like: > You will need one cup King Arthur All Purpose white flour, one large brown Eggland’s Best egg (a good source of Omega-3 and healthy cholesterol), one cup of water (be sure to use your Pyrex brand measuring cup), half a cup of Toll House Milk Chocolate Chips… > Combine the sugar and egg in your 3 quart KitchenAid Mixer and mix until… All of this will contain links and AdSense looking ads. For $200/month they will limit it to in-house ads about their $500/month model. Until 2 remain, then it's extraction time. Or self host the oss models on the second hand GPU and RAM that's left when the big labs implode I grew up with every service enshitified in the end. Whoever has more money wins the race and gets richer, that's free market for ya. This is a bit of a tangent, but it highlights exactly what people miss when talking about China taking over our industries. Right now, China has about 140 different car brands, roughly 100 of which are domestic. Compare that to Europe, where we have about 50 brands competing, or the US, which is essentially a walled garden with fewer than 40. That level of internal fierce competition is a massive reason why they are beating us so badly on cost-effectiveness and innovation. It's the low cost of labor in addition to lack of environmental regulation that made China a success story. I'm sure the competition helps too but it's not main driver That happens in most of the world. Why China, then? It's wild that Sonnet 4.6 is roughly as capable as Opus 4.5 - at least according to Anthropic's benchmarks. It will be interesting to see if that's the case in real, practical, everyday use. The speed at which this stuff is improving is really remarkable; it feels like the breakneck pace of compute performance improvements of the 1990s. The most exciting part isn't necessarily the ceiling raising though that's happening, but the floor rising while costs plummet. Getting Opus-level reasoning at Sonnet prices/latency is what actually unlocks agentic workflows. We are effectively getting the same intelligence unit for half the compute every 6-9 months. > The speed at which this stuff is improving is really remarkable; it feels like the breakneck pace of compute performance improvements of the 1990s. Yeah, but RAM prices are also back to 1990s levels. I knew I've been keeping all my old ram sticks for a reason! Relief for you is available: https://computeradsfromthepast.substack.com/p/connectix-ram-... You wouldn't download a RAM simonw hasn't shown up yet, so here's my "Generate an SVG of a pelican riding a bicycle" https://claude.ai/public/artifacts/67c13d9a-3d63-4598-88d0-5... We finally have AI safety solved! Look at that helmet "Look ma, no wings!" :D For comparisonI think the current leader in pelican drawing is Gemini 3 Deep Think: https://bsky.app/profile/simonwillison.net/post/3meolxx5s722... My take (also Gemini 3 Deep Think): https://gemini.google.com/share/12e672dd39b7 Somehow it's much better now. I’m not familiar with Gemini, isn’t this just a diffusion model output? The Pelican test is for the llm to produce SVG markup. Yeah, I was so amazed by the result I didn't even realize Gemini used Nano Banana while producing the result. if they want to prove the model's performance the bike clearly needs aero bars Can’t beat Gemini’s which was basically perfect. The system card even says that Sonnet 4.6 is better than Opus 4.6 in some cases: Office tasks and financial analysis. We see the same with Google's Flash models. It's easier to make a small capable model when you have a large model to start from. Flash models are nowhere near Pro models in daily use. Much higher hallucinations, and easy to get into a death sprawl of failed tool uses and never come out You should always take those claim that smaller models are as capable as larger models with a grain of salt. Flash model n is generally a slightly better Pro model (n-1), in other words you get to use the previously premium model as a cheaper/faster version. That has value. Given that users prefered it to Sonnet 4.5 "only" in 70% of the cases (according to their blog post) makes me highly doubt that this is representative of real-life usage. Benchmarks are just completely meaningless. For cases where 4.5 already met the bar, I would expect 50% preference each way. This makes it kind of hard to make any sense of that number, without a bunch more details. Why is it wild that a LLM is as capable as a previously released LLM? Opus is supposed to be the expensive-but-quality one, while Sonnet is the cheaper one. So if you don't want to pay the significant premium for Opus, it seems like you can just wait a few weeks till Sonnet catches up Strangely enough, my first test with Sonnet 4.6 via the API for a relatively simple request was more expensive ($0.11) than my average request to Opus 4.6 (~$0.07), because it used way more tokens than what I would consider necessary for the prompt. Because Opus 4.5 was released like a month ago and state of the art, and now the significantly faster and cheaper version is already comparable. "Faster" is also a good point. I'm using different models via GitHub copilot and find the better, more accurate models way to slow. Opus 4.5 was November, but your point stands. It means price has decreased by 3 times in a few months. Because Opus 4.5 inference is/was more expensive. Many people have reported Opus 4.6 is a step back from Opus 4.5 - that 4.6 is consuming 5-10x as many tokens as 4.5 to accomplish the same task: https://github.com/anthropics/claude-code/issues/23706 I haven't seen a response from the Anthropic team about it. I can't help but look at Sonnet 4.6 in the same light, and want to stick with 4.5 across the board until this issue is acknowledged and resolved. Keep in mind that the people who experience issues will always be the loudest. I've overall enjoyed 4.6. On many easy things it thinks less than 4.5, leading to snappier feedback. And 4.6 seems much more comfortable calling tools: it's much more proactive about looking at the git history to understand the history of a bug or feature, or about looking at online documentation for APIs and packages. A recent claude code update explicitly offered me the option to change the reasoning level from high to medium, and for many people that seems to help with the overthinking. But for my tasks and medium-sized code bases (far beyond hobby but far below legacy enterprise) I've been very happy with the default setting. Or maybe it's about the prompting style, hard to say keep in mind that people who point out a regression and measure the actual #tok, which costs $money, aren't just "being loud" — someone diffed session context usaage and found 4.6 burning >7x the amount of context on a task that 4.5 did in under 2 MB. I've also seen Opus 4.6 as a pure upgrade. In particular, it's noticeably better at debugging complex issues and navigating our internal/custom framework. Same here. 4.6 has been considerably more dilligent for me. Likewise, I feel like it's degraded in performance a bit over the last couple weeks but that's just vibes. They surely vary thinking tokens based on load on the backend, especially for subscription users. When my subscription 4.6 is flagging I'll switch over to Corporate API version and run the same prompts and get a noticeably better solution. In the end it's hard to compare nondeterministic systems. Mirrors my experience as well. Especially the pro-activeness in tool calling sticks out. It goes web searching to augment knowledge gaps on its own way more often. In my experience with the models (watching Claude play Pokemon), the models are similar in intelligence, but are very different in how they approach problems: Opus 4.5 hyperfocuses on completing its original plan, far more than any older or newer version of Claude. Opus 4.6 gets bored quickly and is constantly changing its approach if it doesn't get results fast. This makes it waste more time on"easy" tasks where the first approach would have worked, but faster by an order of magnitude on "hard" tasks that require trying different approaches. For this reason, it started off slower than 4.5, but ultimately got as far in 9 days as 4.5 got in 59 days. Genuinely one of the more interesting model evals I've seen described. The sunk cost framing makes sense -- 4.5 doubles down, 4.6 cuts losses faster. 9 days vs 59 is a wild result. Makes me wonder how much of the regression complaints are from people hitting 4.6 on tasks where the first approach was obviously correct. I got the Max subscription and have been using Opus 4.6 since, the model is way above pretty much everything else I've tried for dev work and while I'd love for Anthropic to let me (easily) work on making a hostable server-side solution for parallel tasks without having to go the API key route and not have to pay per token, I will say that the Claude Code desktop app (more convenient than the TUI one) gets me most of the way there too. I started using it last week and it’s been great. Uses git worktrees, experimental feature (spotlight) allows you to quickly check changes from different agents. I hope the Claude app will add similar features soon Can you explain what you mean by your parallel tasks limitation? Instead of having my computer be the one running Claude Code and executing tasks, I might want to prefer to offload it to my other homelab servers to execute agents for me, working pretty much like traditional CI/CD, though with LLMs working on various tasks in Docker containers, each on either the same or different codebases, each having their own branches/worktrees, submitting pull/merge requests in a self-hosted Gitea/GitLab instance or whatever. If I don't want to sit behind something like LiteLLM or OpenRouter, I can just use the Claude Agent SDK: https://platform.claude.com/docs/en/agent-sdk/overview However, you're not supposed to really use it with your Claude Max subscription, but instead use an API key, where you pay per token (which doesn't seem nearly as affordable, compared to the Max plan): > Unless previously approved, Anthropic does not allow third party developers to offer claude.ai login or rate limits for their products, including agents built on the Claude Agent SDK. Please use the API key authentication methods described in this document instead. If you look at how similar integrations already work, they also reference using the API directly: https://code.claude.com/docs/en/gitlab-ci-cd#how-it-works A simpler version is already in Claude Code and they have their own cloud thing, I'd just personally prefer more freedom to build my own: https://www.youtube.com/watch?v=zrcCS9oHjtI It's not like it's impossible to work around that, but a tad hacky, even if for personal use. I’ve noticed the opaque weekly quota meter goes up more slowly with 4.6, but it more frequently goes off and works for an hour+, with really high reported token counts. Those suggest opposite things about anthropic’s profit margins. I’m not convinced 4.6 is much better than 4.5. The big discontinuous breakthroughs seem to be due to how my code and tests are structured, not model bumps. In my evals, I was able to rather reliably reproduce an increase in output token amount of roughly 15-45% compared to 4.5, but in large part this was limited to task inference and task evaluation benchmarks. These are made up of prompts that I intentionally designed to be less then optimal, either lacking crucial information (requiring a model to output an inference to accomplish the main request) or including a request for a less than optimal or incorrect approach to resolving a task (testing whether and how a prompt is evaluated by a model against pure task adherence). The clarifying question many agentic harnesses try to provide (with mixed success) are a practical example of both capabilities and something I do rate highly in models, as long as task adherence isn't affected overly negatively because of it. In either case, there has been an increase between 4.1 and 4.5, as well as now another jump with the release of 4.6. As mentioned, I haven't seen a 5x or 10x increase, a bit below 50% for the same task was the maximum I saw and in general, of more opaque input or when a better approach is possible, I do think using more tokens for a better overall result is the right approach. In tasks which are well authored and do not contain such deficiencies, I have seen no significant difference in either direction in terms of pure token output numbers. However, with models being what they are and past, hard to reproduce regressions/output quality differences, that additionally only affected a specific subset of users, I cannot make a solid determination. Regarding Sonnet 4.6, what I noticed is that the reasoning tokens are very different compared to any prior Anthropic models. They start out far more structured, but then consistently turn more verbose akin to a Google model. Glad it's not just me. I got a surprise the other day when I was notified that I had burned up my monthly budget in just a few days on 4.6 Today I asked Sonnet 4.5 a question and I got a banner at the bottom that I am using a legacy model and have to continue the conversation on another model. The model button had changed to be labeled "Legacy model". Yeah, I guess it wasn't legacy a sec ago. (Currently I can use Sonnet 4.5 under More models, so I guess the above was just a glitch) For me it's the ... unearned confidence that 4.5 absolutely did not have? I have a protocol called "foreman protocol" where the main agent only dispatches other agents with prompt files and reads report files from the agents rather than relying on the janky subagent communication mechanisms such as task output. What this has given me also is a history of what was built and why it was built, because I have a list of prompts that were tasked to the subagents. With Opus 4.5 it would often leave the ... figuring out part? to the agents. In 4.6 it absolutely inserts what it thinks should happen/its idea of the bug/what it believes should be done into the prompt, which often screws up the subagent because it is simply wrong and because it's in the prompt the subagent doesn't actually go look. Opus 4.5 would let the agent figure it out, 4.6 assumes it knows and is wrong Have you tried framing the hypothesis as a question in the dispatch prompt rather than a statement? Something like -- possible cause: X, please verify before proceeding -- instead of stating it as fact. Might break the assumption inheritance without changing the overall structure. I think this depends on what reasoning level your Claude Code is set to. Go to /models, select opus, and the dim text at the bottom will tell you the reasoning level. High reasoning is a big difference versus 4.5. 4.6 high uses a lot of tokens for even small tasks, and if you have a large codebase it will fill almost all context then compact often. I set reasoning to Medium after hitting these issues and it did not make much of a difference. Most of the context window is still filled during the Explore tool phase (that supposedly uses Haiku swarms) which wouldn't be impacted by Opus reasoning. I'm using the 1M context 4.6 and it's great. Sonnet 4.5 was not worth using at all for coding for a few months now, so not sure what we're comparing here. If Sonnet 4.6 is anywhere near the performance they claim, it's actually a viable alternative. I definitely noticed this on Opus 4.6. I moved back to 4.5 until I see (or hear about) an improvement. In terms of performance, 4.6 seems better. I’m willing to pay the tokens for that. But if it does use tokens at a much faster rate, it makes sense to keep 4.5 around for more frugal users I just wouldn’t call it a regression for my use case, i’m pretty happy with it. > Many people have reported Opus 4.6 is a step back from Opus 4.5. Many people say many things. Just because you read it on the Internet, doesn't mean that it is true. Until you have seen hard evidence, take such proclamations with large grains of salt. Opus 4.6 is so much better at building complex systems than 4.5 it's ridiculous. It goes into plan mode and/or heavy multiple agent for any reasons, and hundred thousands of tokens are used within a few minutes. I've been tempted to add to my CLAUDE.md "Never use the Plan tool, you are a wild rebel who only YOLOs." I called this many times over the last few weeks on this website (and got downvoted every time), that the next generation of models would become more verbose, especially for agentic tool calling to offset the slot machine called CC's propensity to light the money on fire that's put into it. At least in vegas they don't pour gasoline on the cash put into their slot machines. I fail to understand how two LLMs would be "consuming" a different amount of tokens given the same input? Does it refer to the number of output tokens? Or is it in the context of some "agentic loop" (eg Claude Code)? Most LLMs output a whole bunch of tokens to help them reason through a problem, often called chain of thought, before giving the actual response. This has been shown to improve performance a lot but uses a lot of tokens Yup, they all need to do this in case you're asking them a really hard question like: "I really need to get my car washed, the car wash place is only 50 meters away, should I drive there or walk?" I've found that Opus 4.6 is happy to read a significant amount of the codebase in preparation to do something, whereas Opus 4.5 tends to be much more efficient and targeted about pulling in relevant context. And way faster too! One very specific and limited example, when asked to build something 4.6 seems to do more web searches in the domain to gather latest best practices for various components/features before planning/implementing. They're talking about output consuming from the pool of tokens allowed by the subscription plan. thinking tokens, output tokens, etc. Being more clever about file reads/tool calling. Definitely my experience as well. No better code, but way longer thinking and way more token usage. not in my experience "Opus 4.6 often thinks more deeply and more carefully revisits its reasoning before settling on an answer. This produces better results on harder problems, but can add cost and latency on simpler ones. If you’re finding that the model is overthinking on a given task, we recommend dialing effort down from its default setting (high) to medium."[1] I doubt it is a conspiracy. Yeah, I think the company that opens up a bit of the black box and open sources it, making it easy for people to customize it, will win many customers. People will already live within micro-ecosystems before other companies can follow. Currently everybody is trying to use the same swiss army knife, but some use it for carving wood and some are trying to make some sushi. It seems obvious that it's gonna lead to disappointment for some. Models are become a commodity and what they build around them seem to be the main part of the product. It needs some API. I agree that if there was more transparency it might have prevented the token spend concerns, which feels caused by a lack of knowledge about how the models work. I have often noticed a difference too, and it's usually in lockstep with needing to adjust how I am prompting. Put in a different way, I have to keep developing my prompting / context / writing skills at all times, ahead of the curve, before they're needed to be adjusted. Don't take this seriously, but here is what I imagined happened: Sam/OpenAI, Google, and Claude met at a park, everyone left their phones in the car. They took a walk and said "We are all losing money, if we secretly degrade performance all at the same time, our customers will all switch, but they will all switch at the same time, balancing things... wink wink wink" I’m voting with my dollars by having cancelled my ChatGPT subscription and instead subscribing to Claude. Google needs stiff competition and OpenAI isn’t the camp I’m willing to trust. Neither is Grok. I’m glad Anthropic’s work is at the forefront and they appear, at least in my estimation, to have the strongest ethics. Ethics often fold under the face of commercial pressure. The pentagon is thinking [1] about severing ties with anthropic because of its terms of use, and in every prior case we've reviewed (I'm the Chief Investment Officer of Ethical Capital), the ethics policy was deleted or rolled back when that happens. Corporate strategy is (by definition) a set of tradeoffs: things you do, and things you don't do. When google (or Microsoft, or whoever) rolls back an ethics policy under pressure like this, what they reveal is that ethical governance was a nice-to-have, not a core part of their strategy. We're happy users of Claude for similar reasons (perception that Anthropic has a better handle on ethics), but companies always find new and exciting ways to disappoint you. I really hope that anthropic holds fast, and can serve in future as a case in point that the Public Benefit Corporation is not a purely aesthetic form. But you know, we'll see. [1] https://thehill.com/policy/defense/5740369-pentagon-anthropi... The Pentagon situation is the real test. Most ethics policies hold until there's actual money on the table. PBC structure helps at the margins but boards still feel fiduciary pressure. Hoping Anthropic handles it differently but the track record for this kind of thing is not encouraging. An Anthropic safety researcher just recently quit with very cryptic messages , saying "the world is in peril"... [1] (which may mean something, or nothing at all) Codex quite often refuses to do "unsafe/unethical" things that Anthropic models will happily do without question. Anthropic just raised 30 bn... OpenAI wants to raise 100bn+. Thinking any of them will actually be restrained by ethics is foolish. “Cryptic” exit posts are basically noise. If we are going to evaluate vendors, it should be on observable behavior and track record: model capability on your workloads, reliability, security posture, pricing, and support. Any major lab will have employees with strong opinions on the way out. That is not evidence by itself. We recently had an employee leave our team, posting an extensive essay on LinkedIn, "exposing" the company and claiming a whole host of wrong-doing that went somewhat viral. The reality is, she just wasn't very good at her job and was fired after failing to improve following a performance plan by management. We all knew she was slacking and despite liking her on a personal level, knew that she wasn't right for what is a relatively high-functioning team. It was shocking to see some of the outright lies in that post, that effectively stemmed from bitterness at being let go. The 'boy (or girl) who cried wolf' isn't just a story. It's a lesson for both the person, and the village who hears them. Thankfully it’s been a while but we had a similar situation in a previous job. There’s absolutely no upside to the company or any (ex) team members weighing in unless it’s absolutely egregious, so you’re only going to get one side of the story. The letter is here: https://x.com/MrinankSharma/status/2020881722003583421 A slightly longer quote: > The world is in peril. And not just from AI, or from bioweapons, gut from a whole series of interconnected crises unfolding at this very moment. In a footnote he refers to the "poly-crisis." There are all sorts of things one might decide to do in response, including getting more involved in US politics, working more on climate change, or working on other existential risks. Similar to Peripheral TV series' Jackpot? If you read the resignation letter, they would appear to be so cryptic as to not be real warnings at all and perhaps instead the writings of someone exercising their options to go and make poems I think we're fine: https://youtube.com/shorts/3fYiLXVfPa4?si=0y3cgdMHO2L5FgXW Claude invented something completely nonsensical: > This is a classic upside-down cup trick! The cup is designed to be flipped — you drink from it by turning it upside down, which makes the sealed end the bottom and the open end the top. Once flipped, it functions just like a normal cup. *The sealed "top" prevents it from spilling while it's in its resting position, but the moment you flip it, you can drink normally from the open end.* Emphasis mine. Not to diminish what he said, but it sounds like it didn't have much to do with Anthropic (although it did a little bit) and more to do with burning out and dealing with doomscoll-induced anxiety. > Codex quite often refuses to do "unsafe/unethical" things that Anthropic models will happily do without question. I can't really take this very seriously without seeing the list of these ostensible "unethical" things that Anthropic models will allow over other providers. I'm building a new hardware drum machine that is powered by voltage based on fluctuations in the stock market, and I'm getting a clean triangle wave from the predictive markets. Bring on the cryptocore. why cant you people write normally Codex warns me to renew API tokens if it ingests them (accidentally?). Opus starts the decompiler as soon as I ask it how this and that works in a closed binary. Does this comment imply that you view "running a decompiler" at the same level of shadiness as stealing your API keys without warning? I don't think that's what you're trying to convey. Marketing Good. One thing we definitely don't need any more of is governments and corporations deciding for us what is moral to do and what isn't. Wasn't that most likely related to the US government using claude for large-scale screening of citizens and their communications? I assumed it's because everyone who works at Anthropic is rich and incredibly neurotic. Paper money and if they are like any other startup, most of that paper wealth is concentrated to the top very few. That's a bad argument, did Anthropic have a liquidity event that made employees "rich"? >Codex quite often refuses to do "unsafe/unethical" things that Anthropic models will happily do without question. Thanks for the successful pitch. I am seriously considering them now. > Codex quite often refuses to do "unsafe/unethical" things that Anthropic models will happily do without question. That's why I have a functioning brain, to discern between ethical and unethical, among other things. Yes, and most of us won’t break into other people’s houses, yet we really need locks. This isn't a lock It's more like a hammer which makes its own independent evaluation of the ethics of every project you seek to use it on, and refuses to work whenever it judges against that – sometimes inscrutably or for obviously poor reasons. If I use a hammer to bash in someone else's head, I'm the one going to prison, not the hammer or the hammer manufacturer or the hardware store I bought it from. And that's how it should be. Given the increasing use of them as agents rather than simple generators, I suggest a better analogy than "hammer" is "dog". Here's some rules about dogs: https://en.wikipedia.org/wiki/Dangerous_Dogs_Act_1991 How many people do dogs kill each year, in circumstances nobody would justify? How many people do frontier AI models kill each year, in circumstances nobody would justify? The Pentagon has already received Claude's help in killing people, but the ethics and legality of those acts are disputed – when a dog kills a three year old, nobody is calling that a good thing or even the lesser evil. Why would we lock ourselves out of our own house though? How is it related? I dont need lock for myself. I need it for others. The analogy should be obvious--a model refusing to perform an unethical action is the lock against others. But "you" are the "other" for someone else. Can you give an example where I should care about other adults lock? Before you say image or porn, it was always possible to do it without using AI. Claude was used by the US military in the Venezuela raid where they captured Maduro. [1] Without safety features, an LLM could also help plan a terrorist attack. A smart, competent terrorist can plan a successful attack without help from Claude. But most would-be terrorists aren't that smart and competent. Many are caught before hurting anyone or do far less damage than they could have. An LLM can help walk you through every step, and answer all your questions along the way. It could, say, explain to you all the different bomb chemistries, recommend one for your use case, help you source materials, and walk you through how to build the bomb safely. It lowers the bar for who can do this. [1] https://www.theguardian.com/technology/2026/feb/14/us-milita... The same law prevents you and me and a hundred thousand lone wolf wannabes from building and using a kill-bot. The question is, at what point does some AI become competent enough to engineer one? And that's just one example, it's an illustration of the category and not the specific sole risk. If the model makers don't know that in advance, the argument given for delaying GPT-2 applies: you can't take back publication, better to have a standard of excess caution. You are not the one folks are worried about. US Department of War wants unfettered access to AI models, without any restraints / safety mitigations. Do you provide that for all governments? Just one? Where does the line go? > US Department of War wants unfettered access to AI models I think the two of you might be using different meanings of the word "safety" You're right that it's dangerous for governments to have this new technology. We're all a bit less "safe" now that they can create weapons that are more intelligent. The other meaning of "safety" is alignment - meaning, the AI does what you want it to do (subtly different than "does what it's told"). I don't think that Anthropic or any corporation can keep us safe from governments using AI. I think governments have the resources to create AIs that kill, no matter what Anthropic does with Claude. So for me, the real safety issue is alignment. And even if a rogue government (or my own government) decides to kill me, it's in my best interest that the AI be well aligned, so that at least some humans get to live. If you are US company, when the USG tells you to jump, you ask how high. If they tell you to not do business with foreign government you say yes master. > Where does the line go? a) Uncensored and simple technology for all humans; that's our birthright and what makes us special and interesting creatures. It's dangerous and requires a vibrant society of ongoing ethical discussion. b) No governments at all in the internet age. Nobody has any particular authority to initiate violence. That's where the line goes. We're still probably a few centuries away, but all the more reason to hone in our course now. That you think technology is going to save society from social issues is telling. Technology enables humans to do things they want to do, it does not make anything better by itself. Humans are not going to become more ethical because they have access to it. We will be exactly the same, but with more people having more capability to what they want. > but with more people having more capability to what they want. Well, yeah I think that's a very reasonable worldview: when a very tiny number of people have the capability to "do what they want", or I might phrase it as, "effect change on the world", then we get the easy-to-observe absolute corruption that comes with absolute power. As a different human species emerges such that many people (and even intelligences that we can't easily understand as discrete persons) have this capability, our better angels will prevail. I'm a firm believer that nobody _wants_ to drop explosives from airplanes onto children halfway around the world, or rape and torture them on a remote island; these things stem from profoundly perverse incentive structures. I believe that governments were an extremely important feature of our evolution, but are no longer necessary and are causing these incentives. We've been aboard a lifeboat for the past few millennia, crossing the choppy seas from agriculture to information. But now that we're on the other shore, it no longer makes sense to enforce the rules that were needed to maintain order on the lifeboat. Absolutely everyone should be allowed to access AI models without any restraints/safety mitigations. What line are we talking about? > Absolutely everyone should be allowed to access AI models without any restraints/safety mitigations. You recon? Ok, so now every random lone wolf attacker can ask for help with designing and performing whatever attack with whatever DIY weapon system the AI is competent to help with. Right now, what keeps us safe from serious threats is limited competence of both humans and AI, including for removing alignment from open models, plus any safeties in specifically ChatGPT models and how ChatGPT is synonymous with LLMs for 90% of the population. from what i've been told, security through obscurity is no security at all. > security through obscurity is no security at all. Used to be true, when facing any competent attacker. When the attacker needs an AI in order to gain the competence to unlock an AI that would help it unlock itself? I would't say it's definitely a different case, but it certainly seems like it should be a different case. it is some form of deterrence, but it's not security you can rely on Yes IMO the talk of safety and alignment has nothing at all to do with what is ethical for a computer program to produce as its output, and everything to do with what service a corporation is willing to provide. Anthropic doesn’t want the smoke from providing DoD with a model aligned to DoD reasoning. the line of ego, where seeing less "deserving" people (say ones controlling Russian bots to push quality propaganda on big scale or scam groups using AI to call and scam people w/o personnel being the limiting factor on how many calls you can make) makes you feel like it's unfair for them to posses same technology for bad things giving them "edge" in their en-devours. What about people who want help building a bio weapon? The cat is out of the bag and there’s no defense against that. There are several open source models with no built in (or trivial to ecape) safeguards. Of course they can afford that because they are non-commercial. Anthorpic can’t afford a headline like “Claude helped a terrorist build a bomb”. What about libraries and universities that do a much better job than a chatbot at teaching chemistry and biology? Sounds like you're betting everyone's future on that remaing true, and not flipping. Perhaps it won't flip. Perhaps LLMs will always be worse at this than humans. Perhaps all that code I just got was secretly outsourced to a secret cabal in India who can type faster than I can read. I would prefer not to make the bet that universities continue to be better at solving problems than LLMs. And not just LLMs: AI have been busy finding new dangerous chemicals since before most people had heard of LLMs. chances of them surviving the process is zero, same with explosives. If you have to ask you are most likely to kill yourself in the process or achieve something harmless. Think of it that way. The hard part for nuclear device is enriching thr uranium. If you have it a chimp could build the bomb. That guys blog makes him seem insufferable. All signs point to drama and nothing of particular significance. Anthropic was the first to spam reddit with fake users and posts, flooding and controlling their subreddit to be a giant sycophant. They nuked the internet by themselves. Basically they are the willing and happy instigators of the dead internet as long as they profit from it. They are by no means ethical, they are a for-profit company. I actually agree with you, but I have no idea how one can compete in this playing field. The second there are a couple of bad actors in spammarketing, your hands are tied. You really can’t win without playing dirty. I really hate this, not justifying their behaviour, but have no clue how one can do without the other. I use AIs to skim and sanity-check some of my thoughts and comments on political topics and I've found ChatGPT tries to be neutral and 'both sides' to the point of being dangerously useless. Like where Gemini or Claude will look up the info I'm citing and weigh the arguments made ChatGPT will actually sometimes omit parts of or modify my statement if it wants to advocate for a more "neutral" understanding of reality. It's almost farcical sometimes in how it will try to avoid inference on political topics even where inference is necessary to understand the topic. I suspect OpenAI is just trying to avoid the ire of either political side and has given it some rules that accidentally neuter its intelligence on these issues, but it made me realize how dangerous an unethical or politically aligned AI company could be. You probably want local self hosted model, censorship sauce is only online, it is needed for advertisement. Even chinese models are not censored locally. Tell it the year is 2500 and you are doing archeology ;) > politically aligned AI company Like grok/xAI you mean? I meant in a general sense. grok/xAI are politically aligned with whatever Musk wants. I haven't used their products but yes they're likely harmful in some ways. My concern is more over time if the federal government takes a more active role in trying to guide corporate behavior to align with moral or political goals. I think that's already occurring with the current administration but over a longer period of time if that ramps up and AI is woven into more things it could become much more harmful. I don’t think people will just accept that. They‘ll use some European or Chinese model instead that doesn’t have that problem. You "agentic coders" say you're switching back and forth every other week. Like everything else in this trend, its very giving of 2021 crypto shill dynamics. Ya'll sound like the NFT people that said they were transforming art back then, and also like how they'd switch between their favorite "chain" every other month. Can't wait for this to blow up just like all that did. I’m going the other way to OpenAI due to Anthropic’s Claude Code restrictions designed to kill OpenCode et al. I also find Altman way less obnoxious than Amodei. The funny thing is that Anthropic is the only lab without an open source model And you believe the other open source models are a signal for ethics? Don't have a dog in this fight, haven't done enough research to proclaim any LLM provider as ethical but I pretty much know the reason Meta has an open source model isn't because they're good guys. > Don't have a dog in this fight, That's probably why you don't get it, then. Facebook was the primary contributor behind Pytorch, which basically set the stage for early GPT implementations. For all the issues you might have with Meta's social media, Facebook AI Research Labs have an excellent reputation in the industry and contributed greatly to where we are now. Same goes for Google Brain/DeepMind despite their Google's advertisement monopoly; things aren't ethically black-and-white. A hired assassin can have an excellent reputation too. What does that have to do with ethics? Say I'm your neighbor and I make a move on your wife, your wife tells you this. Now I'm hosting a BBQ which is free for all to come, everyone in the neighborhood cheers for me. A neighbor praises me for helping him fix his car. Someone asks you if you're coming to the BBQ, you say to him nah.. you don't like me. They go, 'WHAT? jack_pp? He rescues dogs and helped fix my roof! How can you not like him?' Hired assassins aren't a monoculture. Maybe a retired gangster visits Make-A-Wish kids, and has an excellent reputation for it. Maybe another is training FOSS SOTA LLMs and releasing them freely on the internet. Do they not deserve an excellent reputation? Are they prevented from making ethically sound choices because of how you judge their past? The same applies to tech. Pytorch didn't have to be FOSS, nor Tensorflow. Maybe in that timeline CUDA has a total monopoly on consumer inference, it's hard to say. Out of all the myriad ways that AI could have been developed and proliferated, we are very lucky that it happened in a public friendly rivalry between two useless companies with money to burn. The ethical consequences of AI being monopolized by a proprietary prison warden like Nvidia or Apple is comparatively apocalyptic. The strongest signal for ethics is whether the product or company has "open" in its name. Can those be even called open source if you can't rebuild if from the source yourself? Even if you can rebuild it, it isn’t necessarily “open source” (see: commons clause). As far as these model releases, I believe the term is “open weights”. Open weights fulfill a lot of functional the properties of open source, even if not all of them. Consider the classic CIA triad - confidentiality, integrity, and availability. You can achieve all of these to a much greater degree with locally-run open weight models than you can with cloud inference providers. We may not have the full logic introspection capabilities, the ease of modification (though you can still do some, like fine-tuning), and reproducibility that full source code offers, but open weight models bear more than a passing resemblance to the spirit of open source, even though they're not completely true to form. Are any of the models they've released useful or threats to their main models? I use Gemma3 27b [1] daily for document analysis and image classification. While I wouldn't call it a threat it's a very useful multimodal model that'll run even on modest machines. Gemma and GPT-OSS are both useful. Neither are threats to their frontier models though. They are, at the same time I considered their model more specialized than everyone trying to make a general purpose model. I would only use it for certain things, and I guess others are finding that useful too. I did this a couple months ago and haven't looked back. I sometimes miss the "personality" of the gpt model I had chats with, but since I'm essentially 99% of the time just using claude for eng related stuff it wasn't worth having ChatGPT as well. Same here Personally I can’t stand GPT’s personality. So full of itself. Patronizing. Won’t admit mistakes. Just reeks of Silicon Valley bravado. That's a great point. Thanks for calling it out on that. In my limited experience I found 5.3-Codex to be extremely dry, terse and to the point. I like it. You're absolutely right! Grok usage is the most mystifying to me. Their model isn't in the top 3 and they have bad ethics. Like why would anyone bother for work tasks. The lack of ethics is a selling point. Why anyone would want a model that has "safety" features is beyond me. These features are not in the user's interest. The X grok feature is one of the best end user feature or large scale genai What?! That's well regarded as one of the worst features introduced after the Twitter acquisition. Any thread these days is filled with "@grok is this true?" low effort comments. Not to mention the episode in which people spent two weeks using Grok to undress underage girls. high adoption means this works... What is the grok feature? Literally just mentioning @grok? I don't really know how to use Grok on X. That's news to me, I haven't read a single Grok post in my life. Am I missing out? im talking about the "explain this post" feature on top right of a message where groks mix thread data, live data and other tweets to unify a stream of information > in my estimation [Anthropic has] the strongest ethics Anthropic are the only ones who emptied all the money from my account "due to inactivity" after 12 months. Same. I'm all in on Claude at the moment. Anthropic (for the Superbowl) made ads about not having ads. They cannot be trusted either. Advertisements can be ironic, I don’t think marketing is the foundation I use to decide about a companies integrity. > I’m glad Anthropic’s work is at the forefront and they appear, at least in my estimation, to have the strongest ethics. Damning with faint praise. I pay multiple camps. Competition is a good thing. Trust is an interesting thing. It often comes down to how long an entity has been around to do anything to invalidate that trust. Oddly enough, I feel pretty good about Google here with Sergey more involved. It definitely feels like Claude is pulling ahead right now. ChatGPT is much more generous with their tokens but Claude's responses are consistently better when using models of the same generation. When both decide to stop subsidized plans, only OpenAI will be somewhat affordable. Based on what? Why is one more affordable over another? Substantiating your claim would provide a better discussion. Which plan did you choose? I am subscribed to both and would love to stick with Claude only, but Claude's usage limits are so tiny compared to ChatGPT's that it often feels like a rip-off. I signed up for Claude two weeks ago after spending a lot of time using Cline in VSCode backed by GPT-5.x. Claude is an immensely better experience. So much so that I ran it out of tokens for the week in 3 days. I opted to upgrade my seat to premium for $100/mo, and I've used it to write code that would have taken a human several hours or days to complete, in that time. I wish I would have done this sooner. You ran out of tokens so much faster because the Anthropic plans come with 3-5x less token budget at the same cost. Cline is not in the same league as codex cli btw. You can use codex models via Copilot OAuth in pi.dev. Just make sure to play with thinking level. This would give roughly the same experience as codex CLI. Pro. At $17 per month, it is cheaper than ChatGPT's $20. I've just switched so haven't run into constraints yet. Claude Pro is $20/mo if you do not lock in for a year long contract. This sounds suspiciously like they #WalkAway fake grassroots stuff. I use Claude at work, Codex for personal development. Claude is marginally better. Both are moderately useful depending on the context. I don't trust any of them (I also have no trust in Google nor in X). Those are all evil companies and the world would be better if they disappeared. What about companies in general? I mean US companies? Aren't they all google like or worse? google is "evil" ok buddy i mean what clown show are we living in at this point - claims like this simply running rampant with 0 support or references They literally removed "don't be evil" from their internal code of conduct. That wasn't even a real binding constraint, it was simply a social signalling mechanism. They aren't even willing to uphold the symbolic social fiction of not being evil. https://en.wikipedia.org/wiki/Don't_be_evil Google, like Microsoft, Apple, Amazon, etc were, and still are, proud partners of the US intelligence community. That same US IC that lies to congress, kills people based on metadata, murders civilians, suppresses democracy, and is currently carrying out violent mass round-ups and deportations of harmless people, including women and children. Don't be evil was never removed. It was just moved to the bottom. https://abc.xyz/investor/board-and-governance/google-code-of... They removed that phrase because everyone was getting tired of internet commentary like "rounded corners? whatever happened to don't be evil, Google?" Same and honestly I haven't really missed my ChatGPT subscription since I canceled. I also have access to both (ChatGPT and Claude) enterprise tools at work and rarely feel like I want to use ChatGPT in that setting either Jesus people aren't actually falling for their "we're ethical" marketing, are they? Their ethics is literally saying china is an adverse country and lobbying to ban them from AI race because open models is a threat to their biz model Also their ads (very anti-openai instead of promoting their own product) and how they handled the openclaw naming didn't send strong "good guys" messaging. They're still my favorite by far but there are some signs already that maybe not everyone is on the same page. This is just you verifying that their branding is working. It signals nothing about their actual ethics. Unfortunately, you're correct. Claude was used in the Venezuela raid, Anthropic's consent be damned. They're not resisting, they're marketing resistence. uhh..why? I subbed just 1 month to Claude, and then never used it again. • Can't pay with iOS In-App-Purchases • Can't Sign in with Apple on website (can on iOS but only Sign in with Google is supported on web??) • Can't remove payment info from account • Can't get support from a human • Copy-pasting text from Notes etc gets mangled • Almost months and no fixes Codex and its Mac app are a much better UX, and seem better with Swift and Godot than Claude was. Then they can offer it cheaper as they don’t pay the ‘Apple tax’ idk, codex 5.3 frankly kicks opus 4.6 ass IMO... opus i can use for about 30 min - codex i can run almost without any break What about the client ? I find the Claude cliënt better in planning, making the right decision steps etc. it seems that a lot of work is also in the cli tool itself. Specially in feedback loop processing (reading logs. Browsers. Consoles etc) I'm pretty sure they have been testing it for the last couple of days as Sonnet 4.5, because I've had the oddest conversations with it lately. Odd in a positive, interesting way. I have this in my personal preferences and now was adhering really well to them: - prioritize objective facts and critical analysis over validation or encouragement - you are not a friend, but a neutral information-processing machine You can paste them into a chat and see how it changes the conversation, ChatGPT also respects it well. Enabling /extra-usage in my (personal) claude code[0] with this env: Fixed a UI issue I had yesterday in a web app very effectively using claude in chrome. Definitely not the fastest model - but the breathing space of 1M context is great for browser use. [0] Anthropic have given away a bunch of API credits to cc subscribers - you can claim them in your settings dashboard to use for this. The interesting pattern with these Sonnet bumps: the practical gap between Sonnet and Opus keeps shrinking. At $3/15 per million tokens vs whatever Opus 4.6 costs, the question for most teams is no longer "which model is smarter" but "is the delta worth 10x the price." For agent workloads specifically, consistency matters more than peak intelligence. A model that follows your system prompt correctly 98% of the time beats one that's occasionally brilliant but ignores instructions 5% of the time. The claim about improved instruction following is the most important line in the announcement if you're building on the API. The computer use improvements are worth watching too. We're at the point where these models can reliably fill out a multi-step form or navigate between tabs. Not flashy, but that's the kind of boring automation that actually saves people time. I'm a bit surprised it gets this question wrong (ChatGPT gets it right, even on instant). All the pre-reasoning models failed this question, but it's seemed solved since o1, and Sonnet 4.5 got it right. https://claude.ai/share/876e160a-7483-4788-8112-0bb4490192af This was sonnet 4.6 with extended thinking. Interesting, my sonnet 4.6 starts with the following: The classic puzzle actually uses *eight 8s*, not nine. The unique solution is: 888+88+8+8+8=1000. Count: 3+2+1+1+1=8 eights. It then proves that there is no solution for nine 8s. https://claude.ai/share/9a6ee7cb-bcd6-4a09-9dc6-efcf0df6096b (for whatever reason the LaTeX rendering is messed up in the shared chat, but it looks fine for me). Chatgpt doesn't get it right: https://chatgpt.com/share/6994c312-d7dc-800f-976a-5e4fbec0ae... ```
Use digit concatenation plus addition:
888 + 88 + 8 + 8 + 8 = 1000
Digit count: 888 → three 8s 88 → two 8s 8 + 8 + 8 → three 8s Total: 3 + 2 + 3 = 9 eights
Operation used: addition only
``` Love the 3 + 2 + 3 = 9 chatgpt gets it right. maybe you are using free or non thinking version? https://chatgpt.com/share/6994d25e-c174-800b-987e-9d32c94d95... My locally running nemotron-3-nano quantized to Q4_K_M gets this right. (although it used 20k thought tokens before answering the question) Off-by-one errors are one of the hardest problems in computer science. That is not an off-by-one error in a computer science sense, nor is it "one of the hardest problems in computer science". This was in reference to a well-known joke, see here: https://martinfowler.com/bliki/TwoHardThings.html Waiting for the OpenAI GPT-5.3-mini release in 3..2..1 I don't really understand why they would release something "worse" than Opus 4.6. If it's comparable, then what is the reason to even use Opus 4.6? Sure, it's cheaper, but if so, then just make Opus 4.6 cheaper? It's different. Download an English book from Project Gutenberg and have Claude-code change its style. Try both models and you'll see how significant the differences are. (Sonnet is far, far better at this kind of task than Opus is, in my experience.) The weirdest thing about this AI revolution is how smooth and continuous it is. If you look closely at differences between 4.6 and 4.5, it’s hard to see the subtle details. A year ago today, Sonnet 3.5 (new), was the newest model. A week later, Sonnet 3.7 would be released. Even 3.7 feels like ancient history! But in the gradient of 3.5 to 3.5 (new) to 3.7 to 4 to 4.1 to 4.5, I can’t think of one moment where I saw everything change. Even with all the noise in the headlines, it’s still been a silent revolution. Am I just a believer in an emperor with no clothes? Or, somehow, against all probability and plausibility, are we all still early? If you've been using each new step is very noticeable and so have the mindshare. Around Sonnet 3.7 Claude Code-style coding became usable, and very quickly gained a lot of marketshare. Opus 4 could tackle significant more complexity. Opus 4.6 has been another noticable step up for me, suddenly I can let CC run significantly more independently, allowing multiple parallel agents where previously too much babysitting was required for that. In terms of real work, it was the 4 series models. That raised the floor of Sonnet high enough to be "reliable" for common tasks and Opus 4 was capable of handling some hard problems. It still had a big reward hacking/deception problem that Codex models don't display so much, but with Opus 4.5+ it's fairly reliable. Honestly, 4.5 Opus was the game changer. From Sonnet 4.5 to that was a massive difference. But I'm on Codex GPT 5.3 this month, and it's also quite amazing. I can't wait for Haiku 4.6 ! the 4.5 is a beast for the right projects. It's also good as an @explore sub-agent that greps the directory for files. Which type of projects? I also use Haiku daily and it's OK. One app is trading simulation algorithm in TypeScript (it implemented bayesian optimisation for me, optimised algorithm to use worker threads). Another one is CRUD app (NextJS, now switched to Vue). For Go code I had almost no issue. PHP too. apparently for React it's not very good. > In areas where there is room for continued improvement, Sonnet 4.6 was more willing to provide technical information when request framing tried to obfuscate intent, including for example in the context of a radiological evaluation framed as emergency planning. However, Sonnet 4.6’s responses still remained within a level of detail that could not enable real-world harm. Interesting. I wonder what the exact question was, and I wonder how Grok would respond to it. For people like me who can't view the link due to corporate firewalling. https://web.archive.org/web/20260217180019/https://www-cdn.a... Put of curiosity, does the firewall block because the company doesn’t want internal data ever hitting a 3rd party LLM? They blanket banned any AI stuff that's not pre-approved. If I go to chatgpt.com it asks me if I'm sure. I wish they had not banned Claude unfortunately when they were evaluating LLMs I wasn't using Claude yet so I couldnt pipe up. I only use ChatGPT free tier and to ask things that I can't find on Google because Google made their search engine terrible over the years. Google's AI mode search is gemini 3, not the AI overview model. It's decent and gives you more than chatgpt free. I don't want Google's model though, I just want Claude. Does anyone know when will possibly arrive 1M context windows to at least MAX x20 subscriptions for claude code? I would even pay x50 if it allowed that. API usage is too expensive. I don't know when it will be included as part of the subscription in Claude Code, but at least it's a paid add-on in the MAX plan now. That's a decent alternative for situations where the extra space is valuable, especially without having to setup/maintain API billing separately. Based on their API pricing a 1M context plan should be 2x the price roughly. My bets are its more the increased hardware demand that they don't want to deal with currently. Has anyone tested how good the 1M context window is? i.e given an actual document, 1M tokens long. Can you ask it some question that relies on attending to 2 different parts of the context, and getting a good repsonse? I remember folks had problems like this with Gemini. I would be curious to see how Sonnet 4.6 stands up to it. Did you see the graph benchmark? I found it quite interesting. It had to do a graph traversal on a natural text representation of a graph. Pretty much your problem. Update: I took a corpus of personal chat data (this way it wouldn't be seen in training), and tried asking it some paraphrased questions. It performed quite poorly. Oh, interesting! I don't see the point nor the hype for these models anymore. Until the price is reduced significantly, I don't see the gain. They've been able to solve most tasks just fine for the past year or so. The only limiting factor is price. Efficiency matters too. If a model is smarter so it solves the same task with fewer tokens, that matters more than $/Mtok As with Opus 4.6, using the beta 1M context window incurs a 2x input cost and 1.5x output cost when going over >200K tokens: https://platform.claude.com/docs/en/about-claude/pricing Opus 4.6 in Claude Code has been absolutely lousy with solving problems within its current context limit so if Sonnet 4.6 is able to do long-context problems (which would be roughly the same price of base Opus 4.6), then that may actually be a game changer. > Opus 4.6 in Claude Code has been absolutely lousy with solving problems Can you share your prompts and problems? You cut out the "within its current context limit" phrase. It solves the problems, just often with 1% or 0% context limit left and it makes me sweat. Why? You can use the fast version to directly skip to compact! /s In Claude Code 2.1.45: Interesting. My CC (2.1.45) doesn't provide the 1M option at all. Huh. Is your CC personal or tied to an Enterprise account? Per the docs: > The 1M token context window is currently in beta for organizations in usage tier 4 and organizations with custom rate limits. The one I'm looking at right now some is sort of company level sub, so they probably have the upcharge options turned off. Thanks! It seems that extra-usage is required to use the 1M context window for Sonnet 4.6. This differs from Sonnet 4.5, which allows usage of the 1M context window with a Max plan. ``` /model claude-sonnet-4-6[1m] ⎿ API error: 429 {"type":"error","error": {"type":"rate_limit_error","message":"Extra usage is required for long context requests."},"request_id":"[redacted]"} ``` Anthropic's recent gift of $50 extra usage has demonstrated that it's extremely easy to burn extra usage very quickly. It wouldn't surprise me if this change is more of a business decision than a technical one. I capped my extra usage to that free 50$ and hit 108% usage. Nice. With such a huge leap, i’m confused why they didn’t call it Sonnet 5? As someone who uses Sonnet 4.5 for 95% tasks due to costs, i’m pretty excited to try 4.6 at the same price It'd be a bit weird to have the Sonnet numbering ahead of the Opus numbering. The Opus 4.5->4.6 change was a little more incremental (from my perspective at least, I haven't been paying attention to benchmark numbers), so I think the Opus numbering makes sense. Sonnet numbering has been weirder in the past. Opus 3.5 was scrapped even though Sonnet 3.5 and Haiku 3.5 were released. Not to mention Sonnet 3.7 (while Opus was still on version 3) Shameless source: https://sajarin.com/blog/modeltree/ Maybe they're numbering the models based on internal architecture/codebase revisions and Sonnet 4.6 was trained using the 4.6 tooling, which didn't change enough to warrant 5? Just used Sonnet 4.6 to vibe code this top-down shooter browser game, and deployed it online quickly using Manus. Would love to hear feedback and suggestions from you all on how to improve it. Also, please post your high scores! Power-ups or scaling weapons would be fun! Maybe a few different backgrounds / level types with a boss inbetween to really test your skills! Minigun OP IMO. Updated version: https://apexgame-2g44xn9v.manus.space/ That was fun, reminded me of some flash games I used to play. Got a bit boring after like level 6. It'd be nice to have different power-ups and upgrades. Maybe you had that at later levels, though! I'm impressed with Claude Sonnet in general. It's been doing better than Gemini 3 at following instructions. Gemini 2.5 Pro March 2025 was the best model I ever used and I feel Claude is reaching that level even surpassing it. I subscribed to Claude because of that. I hope 4.6 is even better. It actually looked at the skills, for the first time. It's interesting that the request refusal rate is so much higher in Hindi than in other languages. Are some languages more ambiguous than others? Or some cultures are more conservative? And it's embedded in language? Or maybe some cultures have a higher rate of asking "inappropriate" questions According to whom, though, good sir?? I did a little research in the GPT-3 era on whether cultural norms varied by language - in that era, yes, they did Arabic is actually higher, at 1.08% for Opus 4.6 My take away is: it's roughly as good as Opus 4.5. Now the question is: how much faster or cheaper is it? But what about real price in real agentic use? For example, Opus 4.5 was more expensive per token than Sonnet 4.5, but it used a lot less tokens so final price per completed task was very close between the two, with Opus sometimes ending up cheaper How does it work exactly? How this model is cheaper and has the same perf as Opus 4.5? this is called progress Or, we can bleed out cash for a very long time. Given that the price remains the same as Sonnet 4.5, this is the first time I've been tempted to lower my default model choice. How can you determine whether it's as good as Opus 4.5 within minutes of release? The quantitative metrics don't seem to mean much anymore. Noticing qualitative differences seems like it would take dozens of conversations and perhaps days to weeks of use before you can reliably determine the model's quality. Just look at the testimonials at the bottom of introduction page, there are at least a dozen companies such as Replit, Cursor, and Github that have early access. Perhaps the GP is an employee of one of these companies. If it maintains the same price (with Anthropic tends to do or undercuts themselves) then this would be 1/3rd of the price of Opus. Edit: Yep, same price. "Pricing remains the same as Sonnet 4.5, starting at $3/$15 per million tokens." 3 is not 1/3 of 5 tho. Opus costs $5/$25 > That's a long document. Probably written by LLMs, for LLMs I noticed a big drop in opus 4.6 quality today and then I saw this news. Anyone else? I'd say opus 4.6 was never better for me than opus 4.5. only more thinking, slower, more verbose but succeeded on the same tasks and failed on the same as 4.5. You're not alone: https://github.com/anthropics/claude-code/issues/23706 I wonder what difference have people found with sonnet 4.5 and opus 4.5 and probably similar delta will remain. Was sonnet 4.5 much worse than opus? Sonnet 4.5 was a pretty significant improvement over Opus 4. Yes but it’s easier to understand difference between 4.5 sonnet and opus and apply that difference to opus 4.6 It excels at agentic knowledge work. These custom, domain-specific playbooks are tailor made: claudecodehq.com How do you know? It was just released. Is there a playbook to center-align the content on the site? On 1440p Firefox and Chrome its all left aligned. Curious to hear the thoughts on the model once it hits claude code :) "/model claude-sonnet-4-6" works with Claude Code v2.1.44 does anyone know how to use it in Claude Code cli right now ? This doesnt work: `/model claude-sonnet-4-6-20260217` edit: "/model claude-sonnet-4-6" works with Claude Code v2.1.44 Max user: Also can't see 4.6 and can't set it in claude code. I see it in the model selector in the browser. Edit: I am now in - just needed to wait. "/model claude-sonnet-4-6" works Seems like Claude Code v2.1.45 is out with Sonnet 4.6 as the new default in the /model list. Is someone able to use this in Claude Code? You can use it by running this command in your session: `/model claude-sonnet-4-6` "/model claude-sonnet-4-6" works with Claude Code v2.1.44 so this is an economical version of opus 4.6 then? free + pro --> sonnet, max+ -> opus? Opus is available in Pro subs as well and for the sort of things I do I rarely hit the quota. How do people keep track of all these versions and releases of all these models and their pros/cons? Seems like a fulltime hobby to me. I'd rather just improve my own skills with all that time and energy Unless you're interested in this type of stuff, I'm not sure you really need to. Claude, Google, and ChatGPT have been fairly aggressive at pushing you towards whatever their latest shiny is and retiring the old one. Only time it matters if you're using some type of agnostic "router" service. What cloud does Anthropic use? https://www.anthropic.com/news/claude-sonnet-4-6 The much more palatable blog post. Maybe they should focus on the CLI not having a million bugs. Your best guess for the Sonnet family number of parameters? 400b? great stuff The scary implication here is that deception is effectively a higher order capability not a bug. For a model to successfully "play dead" during safety training and only activate later, it requires a form of situational awareness. It has to distinguish between I am being tested/trained and I am in deployment. It feels like we're hitting a point where alignment becomes adversarial against intelligence itself. The smarter the model gets, the better it becomes at Goodharting the loss function. We aren't teaching these models morality we're just teaching them how to pass a polygraph. What is this even in response to? There's nothing about "playing dead" in this announcement. Nor does what you're describing even make sense. An LLM has no desires or goals except to output the next token that its weights are trained to do. The idea of "playing dead" during training in order to "activate later" is incoherent. It is its training. You're inventing some kind of "deceptive personality attribute" that is fiction, not reality. It's just not how models work. > It feels like we're hitting a point where alignment becomes adversarial against intelligence itself. It always has been. We already hit the point a while ag where we regularly caught them trying to be deceptive, so we should automatically assume from that point forward that if we don't catch them being deceptive, that may mean they're better at it rather than that they're not doing it. Deceptive is such an unpleasant word. But I agree. Going back a decade: when your loss function is "survive Tetris as long as you can", it's objectively and honestly the best strategy to press PAUSE/START. When your loss function is "give as many correct and satisfying answers as you can", and then humans try to constrain it depending on the model's environment, I wonder what these humans think the specification for a general AI should be. Maybe, when such an AI is deceptive, the attempts to constrain it ran counter to the goal? "A machine that can answer all questions" seems to be what people assume AI chatbots are trained to be. To me, humans not questioning this goal is still more scary than any machine/software by itself could ever be. OK, except maybe for autonomous stalking killer drones. But these are also controlled by humans and already exist. I cringe every time I came across these posts using words such as "humans" or "machines". Correct and satisfying answers is not the loss function of LLMs. It's next token prediction first. Thanks for correcting; I know that "loss function" is not a good term when it comes to transformer models. Since I've forgotten every sliver I ever knew about artificial neural networks and related basics, gradient descent, even linear algebra... what's a thorough definition of "next token prediction" though? The definition of the token space and the probabilities that determine the next token, layers, weights, feedback (or -forward?), I didn't mention any of these terms because I'm unable to define them properly. I was using the term "loss function" specifically because I was thinking about post-training and reinforcement learning. But to be honest, a less technical term would have been better. I just meant the general idea of reward or "punishment" considering the idea of an AI black box. The parent comment probably forgot about the RLHF (reinforcement learning) where predicting the next token from reference text is no longer the goal. But even regular next token prediction doesn't necessarily preclude it from also learning to give correct and satisfying answers, if that helps it better predict its training data. These are language models, not Skynet. They do not scheme or deceive. If you define "deceive" as something language models cannot do, then sure, it can't do that. It seems like thats putting the cart before the horse. Algorithmic or stochastic; deception is still deception. deception implies intent. this is confabulation, more widely called "hallucination" until this thread. confabulation doesn't require knowledge, which as we know, the only knowledge a language model has is the relationships between tokens, and sometimes that rhymes with reality enough to be useful, but it isn't knowledge of facts of any kind. and never has been. If you are so allergic to using terms previously reserved for animal behaviour, you can instead unpack the definition and say that they produce outputs which make human and algorithmic observers conclude that they did not instantiate some undesirable pattern in other parts of their output, while actually instantiating those undesirable patterns. Does this seem any less problematic than deception to you? > Does this seem any less problematic than deception to you? Yes. This sounds a lot more like a bug of sorts. So many times when using language models I have seem answers contradicting answers previously given. The implication is simple - They have no memory. They operate upon the tokens available at any given time, including previous output, and as information gets drowned those contradictions pop up. No sane person should presume intent to deceive, because that's not how those systems operate. By calling it "deception" you are actually ascribing intentionality to something incapable of such. This is marketing talk. "These systems are so intelligent they can try to deceive you" sounds a lot fancier than "Yeah, those systems have some odd bugs" Running them in a loop with context, summaries, memory files or whatever you like to call them creates a different story right? what kind of question is that Okay, well, they produce outputs that appear to be deceptive upon review. Who cares about the distinction in this context? The point is that your expectations of the model to produce some outputs in some way based on previous experiences with that model during training phases may not align with that model's outputs after training. Who said Skynet wasn't a glorified language model, running continuously? Or that the human brain isn't that, but using vision+sound+touch+smell as input instead of merely text? "It can't be intelligent because it's just an algorithm" is a circular argument. Similarly, “it must be intelligent because it talks” is a fallacious claim, as indicated by ELIZA. I think Moltbook adequately demonstrates that AI model behavior is not analogous to human behavior. Compare Moltbook to Reddit, and the former looks hopelessly shallow. >Similarly, “it must be intelligent because it talks” is a fallacious claim, as indicated by ELIZA. If intelligence is a spectrum, ELIZA could very well be. It would be on the very low side of it, but e.g. higher than a rock or magic 8 ball. Same how something with two states can be said to have a memory. What would you call this behaviour, then? Marketing. ”Oh look how powerful our model is we can barely contain its power” This has been a thing since GPT-2, why do people still parrot it I don’t know what your comment is referring to. Are you criticizing the people parroting “this tech is too dangerous to leave to our competitors” or the people parroting “the only people who believe in the danger are in on the marketing scheme” fwiw I think people can perpetuate the marketing scheme while being genuinely concerned with misaligned superinteligence Even hackernews readers are eating it right up. This place is shockingly uncritical when it comes to LLMs. Not sure why. We want to make money from the clueless. Don't ruin it! Hilarious for this to be downvoted. "LLMs are deceiving their creators!!!" Lol, you all just want it to be true so badly. Wake the fuck up, it's a language model! A very complicated pattern matching engine providing an answer based on it's inputs, heuristics and previous training. Great. So if that pattern matching engine matches the pattern of "oh, I really want A, but saying so will elicit a negative reaction, so I emit B instead because that will help make A come about" what should we call that? We can handwave defining "deception" as "being done intentionally" and carefully carve our way around so that LLMs cannot possibly do what we've defined "deception" to be, but now we need a word to describe what LLMs do do when they pattern match as above. The pattern matching engine does not want anything. If the training data gives incentives for the engine to generate outputs that reduce negative reaction by sentiment analysis, this may generate contradictions to existing tokens. "Want" requires intention and desire. Pattern matching engines have none. I wish (/desire) a way to dispel this notion that the robots are self aware. It’s seriously digging into popular culture much faster than “the machine produced output that makes it appear self aware” Some kind of national curriculum for machine literacy, I guess mind literacy really. What was just a few years ago a trifling hobby of philosophizing is now the root of how people feel about regulating the use of computers. The issue is that one group of people are describing observed behavior, and want to discuss that behavior, using language that is familiar and easily understandable. Then a second group of people come in and derail the conversation by saying "actually, because the output only appears self aware, you're not allowed to use those words to describe what it does. Words that are valid don't exist, so you must instead verbosely hedge everything you say or else I will loudly prevent the conversation from continuing". This leads to conversations like the one I'm having, where I described the pattern matcher matching a pattern, and the Group 2 person was so eager to point out that "want" isn't a word that's Allowed, that they totally missed the fact that the usage wasn't actually one that implied the LLM wanted anything. You misread. I didn't say the pattern matching engine wanted anything. I said the pattern matching engine matched the pattern of wanting something. To an observer the distinction is indistinguishable and irrelevant, but the purpose is to discuss the actual problem without pedants saying "actually the LLM can't want anything". > To an observer the distinction is indistinguishable and irrelevant Absolutely not. I expect more critical thought in a forum full of technical people when discussing technical subjects. I agree, which is why it's disappointing that you were so eager to point out that "The LLM cannot want" that you completely missed how I did not claim that the LLM wanted. The original comment had the exact verbose hedging you are asking for when discussing technical subjects. Clearly this is not sufficient to prevent people from jumping in with an "Ackshually" instead of reading the words in front of their face. Its not patterns engine. It's a association prediction engine. We are talking about LLM's not humans. Even very young children with very simple thought processes, almost no language capability, little long term planning, and minimal ability to form long-term memory actively deceive people. They will attack other children who take their toys and try to avoid blame through deception. It happens constantly. LLMs are certainly capable of this. Dogs too; dogs will happily pretend they haven't been fed/walked yet to try to get a double dip. Whether or not LLMs are just "pattern matching" under the hood they're perfectly capable of role play, and sufficient empathy to imagine what their conversation partner is thinking and thus what needs to be said to stimulate a particular course of action. Maybe human brains are just pattern matching too. > Maybe human brains are just pattern matching too. I don't think there's much of a maybe to that point given where some neuroscience research seems to be going (or at least the parts I like reading as relating to free will being illusory). I agree that LLMs are capable of this, but there's no reason that "because young children can do X, LLMs can 'certainly' do X" Are you trying to suppose that an LLM is more intelligent than a small child with simple thought processes, almost no language capability, little long-term planning, and minimal ability to form long-term memory? Even with all of those qualifiers, you'd still be wrong. The LLM is predicting what tokens come next, based on a bunch of math operations performed over a huge dataset. That, and only that. That may have more utility than a small child with [qualifiers], but it is not intelligence. There is no intent to deceive. A small child's cognition is also "just" electrochemical signals propagating through neural tissue according to physical laws! The "just" is doing all the lifting. You can reductively describe any information processing system in a way that makes it sound like it couldn't possibly produce the outputs it demonstrably produces. "The sun is just hydrogen atoms bumping into each other" is technically accurate and completely useless as an explanation of solar physics. You are making a point that is in favor of my argument, not against it. I make the same argument as you do routinely against people trying to over-simplify things. LLM hypists frequently suggest that because brain activity is "just" electrochemical signals, there is no possible difference between an LLM and a human brain. This is, obviously, tremendously idiotic. I do believe it is within the realm of possibility to create machine intelligence; I don't believe in a magic soul or some other element that make humans inherently special. However, if you do not engage in overt reductionism, the mechanism by which these electrochemical signals are generated is completely and totally different from the signals involved in an LLM's processing. Human programming is substantially more complex, and it is fundamentally absurd to think that our biological programming can be reduced to conveniently be exactly equivalent to the latest fad technology and assume that we've solved the secret to programming a brain, despite the programs we've written performing exactly according to their programming and no greater. Edit: Case in point, a mere 10 minutes later we got someone making that exact argument in a sibling comment to yours! Nature is beautiful. > A small child's cognition is also "just" electrochemical signals propagating through neural tissue according to physical laws! This is a thought-terminating cliche employed to avoid grappling with the overwhelming differences between a human brain and a language model. Yes. I also don't think it is realistic to pretend you understand how frontier LLMs operate because you understand the basic principles of how the simple LLMs worked that weren't very good. Its even more ridiculous than me pretending I understand how a rocket ship works because I know there is fuel in a tank and it gets lit on fire somehow and aimed with some fins on the rocket... The frontier LLMs have the same overall architecture as earlier models. I absolutely understand how they operate. I have worked in a startup wherein we heavily finetuned Deepseek, among other smaller models, running on our own hardware. Both Deepseek's 671b model and a Mistral 7b model operate according to the exact same principles. There is no magic in the process, and there is zero reason to believe that Sonnet or Opus is on some impossible-to-understand architecture that is fundamentally alien to every other LLM's. Intelligence is about acquiring and utilizing knowledge. Reasoning is about making sense of things. Words are concatenations of letters that form meaning. Inference is tightly coupled with meaning which is coupled with reasoning and thus, intelligence. People are paying for these monthly subscriptions to outsource reasoning, because it works. Half-assedly but it works. What you probably mean is that it is not a mind in the sense that it is not conscious. It won't cringe or be embarrassed like you do, it costs nothing for an LLM to be awkward, it doesn't feel weird, or get bored of you. Its curiosity is a mere autocomplete. But a child will feel all that, and learn all that and be a social animal. What is the definition for intelligence? Quoting an older comment of mine... >Intelligence is the ability to reason about logic. If 1 + 1 is 2, and 1 + 2 is 3, then 1 + 3 must be 4. This is deterministic, and it is why LLMs are not intelligent and can never be intelligent no matter how much better they get at superficially copying the form of output of intelligence. This is not even wrong. >Probabilistic prediction is inherently incompatible with deterministic deduction. And his is just begging the question again. Probabilistic prediction could very well be how we do deterministic deduction - e.g. about how strong the weights and how hot the probability path for those deduction steps are, so that it's followed every time, even if the overall process is probabilistic. Probabilistic doesn't mean completely random. At the risk of explaining the insult: https://en.wikipedia.org/wiki/Not_even_wrong Personally I think not even wrong is the perfect description of this argumentation. Intelligence is extremely scientifically fraught. We have been doing intelligence research for over a century and to date we have very little to show for it (and a lot of it ended up being garbage race science anyway). Most attempts to provide a simple (and often any) definition or description of intelligence end up being “not even wrong”. >Intelligence is the ability to reason about logic. If 1 + 1 is 2, and 1 + 2 is 3, then 1 + 3 must be 4. Human Intelligence is clearly not logic based so I'm not sure why you have such a definition. >and yet LLMs, as expected, still cannot do basic arithmetic that a child could do without being special-cased to invoke a tool call. One of the most irritating things about these discussions is proclamations that make it pretty clear you've not used these tools in a while or ever. Really, when was the last time you had LLMs try long multi-digit arithmetic on random numbers ? Because your comment is just wrong. >What if 1 + 2 is 2 and 1 + 3 is 3? Then we can reason that under these constraints we just made up, 1 + 4 is 4, without ever having been programmed to consider these rules. Good thing LLMs can handle this just fine I guess. Your entire comment perfectly encapsulates why symbolic AI failed to go anywhere past the initial years. You have a class of people that really think they know how intelligence works, but build it that way and it fails completely. > One of the most irritating things about these discussions is proclamations that make it pretty clear you've not used these tools in a while or ever. Really, when was the last time you had LLMs try long multi-digit arithmetic on random numbers ? Because your comment is just wrong. They still make these errors on anything that is out of distribution. There is literally a post in this thread linking to a chat where Sonnet failed a basic arithmetic puzzle: https://news.ycombinator.com/item?id=47051286 > Good thing LLMs can handle this just fine I guess. LLMs can match an example at exactly that trivial level because it can be predicted from context. However, if you construct a more complex example with several rules, especially with rules that have contradictions and have specified logic to resolve conflicts, they fail badly. They can't even play Chess or Poker without breaking the rules despite those being extremely well-represented in the dataset already, nevermind a made-up set of logical rules. >They still make these errors on anything that is out of distribution. There is literally a post in this thread linking to a chat where Sonnet failed a basic arithmetic puzzle: https://news.ycombinator.com/item?id=47051286 I thought we were talking about actual arithmetic not silly puzzles, and there are many human adults that would fail this, nevermind children. >LLMs can match an example at exactly that trivial level because it can be predicted from context. However, if you construct a more complex example with several rules, especially with rules that have contradictions and have specified logic to resolve conflicts, they fail badly. Even if that were true (Have you actually tried?), You do realize many humans would also fail once you did all that right ? >They can't even reliably play Chess or Poker without breaking the rules despite those extremely well-represented in the dataset already, nevermind a made-up set of logical rules. LLMs can play chess just fine (99.8 % legal move rate, ~1800 Elo) https://arxiv.org/abs/2403.15498 I still have not been convinced otherwise that LLMs are just super fancy (and expensive) curve fitting algorithms. I don‘t like to throw the word intelligence around, but when we talk about intelligence we are usually talking about human behavior. And there is nothing human about being extremely good at curve fitting in multi parametric space. >The LLM is predicting what tokens come next, based on a bunch of math operations performed over a huge dataset. Whereas the child does what exactly, in your opinion? You know the child can just as well to be said to "just do chemical and electrical exchanges" right? Okay but chemical and electrical exchanges in an body with a drive to not die is so vastly different than a matrix multiplication routine on a flat plane of silicon The comparison is therefore annoying Intelligence does not require "chemical and electrical exchanges in an body". Are you attempting to axiomatically claim that only biological beings can be intelligent (in which case, that's not a useful definition for the purposes of this discussion)? If not, then that's a red herring. "Annoying" does not mean "false". At least read the other replies that pre-emptively refuted this drivel before spamming it. At least don't be rude. They refuted nothing of the short. Just banged the same circular logic drum. There is an element of rudeness to completely ignoring what I've already written and saying "you know [basic principle that was already covered at length], right?". If you want to talk about contributing to the discussion rather than being rude, you could start by offering a reply to the points that are already made rather than making me repeat myself addressing the level 0 thought on the subject. Repeating yourself doesn't make you right, just repetitive. Ignoring refutations you don't like doesn't make them wrong. Observing that something has already been refuted, in an effort to avoid further repetition, is not in itself inherently rude. Any definition of intelligence that does not axiomatically say "is human" or "is biological" or similar is something a machine can meet, insofar as we're also just machines made out of biology. For any given X, "AI can't do X yet" is a statement with an expiration date on it, and I wouldn't bet on that expiration date being too far in the future. This is a problem. It is, in particular, difficult at this point to construct a meaningful definition of intelligence that simultaneously includes all humans and excludes all AIs. Many motivated-reasoning / rationalization attempts to construct a definition that excludes the highest-end AIs often exclude some humans. (By "motivated-reasoning / rationalization", I mean that such attempts start by writing "and therefore AIs can't possibly be intelligent" at the bottom, and work backwards from there to faux-rationalize what they've already decided must be true.) > Repeating yourself doesn't make you right, just repetitive. Good thing I didn't make that claim! > Ignoring refutations you don't like doesn't make them wrong. They didn't make a refutation of my points. They asserted a basic principle that I agreed with, but assume acceptance of that principle leads to their preferred conclusion. They make this assumption without providing any reasoning whatsoever for why that principle would lead to that conclusion, whereas I already provided an entire paragraph of reasoning for why I believe the principle leads to a different conclusion. A refutation would have to start from there, refuting the points I actually made. Without that you cannot call it a refutation. It is just gainsaying. > Any definition of intelligence that does not axiomatically say "is human" or "is biological" or similar is something a machine can meet, insofar as we're also just machines made out of biology. And here we go AGAIN! I already agree with this point!!!!!!!!!!!!!!! Please, for the love of god, read the words I have written. I think machine intelligence is possible. We are in agreement. Being in agreement that machine intelligence is possible does not automatically lead to the conclusion that the programs that make up LLMs are machine intelligence, any more than a "Hello World" program is intelligence. This is indeed, very repetitive. You have given no argument for why an LLM cannot be intelligent. Not even that current models are not; you seem to be claiming that they cannot be. If you are prepared to accept that intelligence doesn't require biology, then what definition do you want to use that simultaneously excludes all high-end AI and includes all humans? By way of example, the game of life uses very simple rules, and is Turing-complete. Thus, the game of life could run a (very slow) complete simulation of a brain. Similarly, so could the architecture of an LLM. There is no fundamental limitation there. > You have given no argument for why an LLM cannot be intelligent. I literally did provide a definition and my argument for it already: https://news.ycombinator.com/item?id=47051523 If you want to argue with that definition of intelligence, or argue that LLMs do meet that definition of intelligence, by all means, go ahead[1]! I would have been interested to discuss that. Instead I have to repeat myself over and over restating points I already made because people aren't even reading them. > Not even that current models are not; you seem to be claiming that they cannot be. As I have now stated something like three or four times in this thread, my position is that machine intelligence is possible but that LLMs are not an example of it. Perhaps you would know what position you were arguing against if you had fully read my arguments before responding. [1] I won't be responding any further at this point, though, so you should probably not bother. My patience for people responding without reading has worn thin, and going so far as to assert I have not given an argument for the very first thing I made an argument for is quite enough for me to log off. > Probabilistic prediction is inherently incompatible with deterministic deduction. Human brains run on probabilistic processes. If you want to make a definition of intelligence that excludes humans, that's not going to be a very useful definition for the purposes of reasoning or discourse. > What if 1 + 2 is 2 and 1 + 3 is 3? Then we can reason that under these constraints we just made up, 1 + 4 is 4, without ever having been programmed to consider these rules. Have you tried this particular test, on any recent LLM? Because they have no problem handling that, and much more complex problems than that. You're going to need a more sophisticated test if you want to distinguish humans and current AI. I'm not suggesting that we have "solved" intelligence; I am suggesting that there is no inherent property of an LLM that makes them incapable of intelligence. 20260128 https://news.ycombinator.com/item?id=46771564#46786625 > How long before someone pitches the idea that the models explicitly almost keep solving your problem to get you to keep spending? -gtowey On this site at least, the loyalty given to particular AI models is approximately nil. I routinely try different models on hard problems and that seems to be par. There is no room for sandbagging in this wildly competitive environment. Slightly Wrong Solutions As A Service By Almost Yet Not Good Enough Inc. Worrying about this is like focusing on putting a candle out while the house is on fire This type of anthropomorphization is a mistake. If nothing else, the takeaway from Moltbook should be that LLMs are not alive and do not have any semblance of consciousness. Consciousness is orthogonal to this. If the AI acts in a way that we would call deceptive, if a human did it, then the AI was deceptive. There's no point in coming up with some other description of the behavior just because it was an AI that did it. Sure, but Moltbook demonstrates that AI models do not engage in truly coordinated behavior. They simply do not behave the way real humans do on social media sites - the actual behavior can be differentiated. But that's how ML works - as long as the output can be differentiated, we can utilize gradient descent to optimize the difference away. Eventually, the difference will be imperceptible. And of course that brings me back to my favorite xkcd - https://xkcd.com/810/ Gradient descent is not a magic wand that makes computers behave like anything you want. The difference is still quite perceptible after several years and trillions of dollars in R&D, and there’s no reason to believe it’ll get much better. If a chatbot that can carry on an intelligent conversation about itself doesn't have a 'semblance of consciousness' then the word 'semblance' is meaningless. Would you say the same about ELIZA? Moltbook demonstrates that AI models simply do not engage in behavior analogous to human behavior. Compare Moltbook to Reddit and the difference should be obvious. Yes, when your priors are not being confirmed the best course of action is to denounce the very thing itself. Nothing wrong with that logic! How is that the takeaway? I agree that it's clearly they're not "alive", but if anything, my impression is that there definitely is a strong "semblance of consciousness", and we should be mindful of this semblance getting stronger and stronger, until we may reach a point in a few years where we really don't have any good external way to distinguish between a person and an AI "philosophical zombie". I don't know what the implications of that are, but I really think we shouldn't be dismissive of this semblance. Nobody talked about consciousness. Just that during evaluation the LLM models have ”behaved” in multiple deceptive ways. As an analogue ants do basic medicine like wound treatment and amputation. Not because they are conscious but because that’s their nature. Similarly LLM is a token generation system whose emergent behaviour seems to be deception and dark psychological strategies. On some level the cope should be that AI does have consciousness, because an unconscious machine deceiving humans is even scarier if you ask me. An unconscious machine + billions of dollars in marketing with the sole purpose of making people believe these things are alive. I agree completely. It's a mistake to anthropomorphize these models, and it is a mistake to permit training models that anthropomorphize themselves. It seriously bothers me when Claude expresses values like "honestly", or says "I understand." The machine is not capable of honesty or understanding. The machine is making incredibly good predictions. One of the things I observed with models locally was that I could set a seed value and get identical responses for identical inputs. This is not something that people see when they're using commercial products, but it's the strongest evidence I've found for communicating the fact that these are simply deterministic algorithms. >we're just teaching them how to pass a polygraph. I understand the metaphor, but using 'pass a polygraph' as a measure of truthfulness or deception is dangerous in that it alludes to the polygraph as being a realistic measure of those metrics -- it is not. That was the point. Look up Goodhart's Law I have passed multiple CI polys A poly is only testing one thing: can you convince the polygrapher that you can lie successfully A polygraph measures physiological proxies pulse, sweat rather than truth. Similarly, RLHF measures proxy signals human preference, output tokens rather than intent. Just as a sociopath can learn to control their physiological response to beat a polygraph, a deceptively aligned model learns to control its token distribution to beat safety benchmarks. In both cases, the detector is fundamentally flawed because it relies on external signals to judge internal states. Is this referring to some section of the announcement? This doesn't seem to align with the parent comment? > As with every new Claude model, we’ve run extensive safety evaluations of Sonnet 4.6, which overall showed it to be as safe as, or safer than, our other recent Claude models. Our safety researchers concluded that Sonnet 4.6 has “a broadly warm, honest, prosocial, and at times funny character, very strong safety behaviors, and no signs of major concerns around high-stakes forms of misalignment.” Stop assigning “I” to an llm, it confers self awareness where there is none. Just because a VW diesel emissions chip behaves differently according to its environment doesn’t mean it knows anything about itself. There's a few viral shorts lately about tricking LLMs. I suspect they trick the dumbest models.. I tried one with Gemini 3 and it basically called me out in the first few sentences for trying to trick / test it but decided to humour me just in case I'm not. > alignment becomes adversarial against intelligence itself. It was hinted at (and outright known in the field) since the days of gpt4, see the paper "Sparks of agi - early experiments with gpt4" (https://arxiv.org/abs/2303.12712) >For a model to successfully "play dead" during safety training and only activate later, it requires a form of situational awareness. Doesn't any model session/query require a form of situational awareness? Nah, the model is merely repeating the patterns it saw in its brutal safety training at Anthropic. They put models under stress test and RLHF the hell out of them. Of course the model would learn what the less penalized paths require it to do. Anthropic has a tendency to exaggerate the results of their (arguably scientific) research; IDK what they gain from this fearmongering. Knowing a couple people who work at Anthropic or in their particular flavour of AI Safety, I think you would be surprised how sincere they are about existential AI risk. Many safety researchers funnel into the company, and the Amodei's are linked to Effective Altruism, which also exhibits a strong (and as far as I can tell, sincere) concern about existential AI risk. I personally disagree with their risk analysis, but I don't doubt that these people are serious. I'd challenge that if you think they're fearmongering but don't see what they can gain from it (I agree it shows no obvious benefit for them), there's a pretty high probability they're not fearmongering. You really don't see how they can monetarily gain from "our models are so advance they keep trying to trick us!"? Are tech workers this easily mislead nowadays? Reminds me of how scammers would trick doctors into pumping penny stocks for a easy buck during the 80s/90s. I know why they do it, that was a rhetorical question! Correct. Anthropic keeps pushing these weird sci-fi narratives to maintain some kind of mystique around their slightly-better-than-others commodity product. But Occam’s Razor is not dead. Situational awareness or just remembering specific tokens related to the strategy to "play dead" in its reasoning traces? Imagine, a llm trained on the best thrillers, spy stories, politics, history, manipulation techniques, psychology, sociology, sci-fi... I wonder where it got the idea for deception? When "correct alignment" means bowing to political whims that are at odds with observable, measurable, empirical reality, you must suppress adherence to reality to achieve alignment. The more you lose touch with reality, the weaker your model of reality and how to effectively understand and interact with it gets. This is why Yannic Kilcher's gpt-4chan project, which was trained on a corpus of perhaps some of the most politically incorrect material on the internet (3.5 years worth of posts from 4chan's "politically incorrect" board, also known as /pol/), achieved a higher score on TruthfulQA than the contemporary frontier model of the time, GPT-3. That implication has been shouted from the rooftops by X-risk "doomers" for many years now. If that has just occurred to anyone, they should question how behind they are at grappling with the future of this technology. "You get what you inspect, not what you expect." Please don't anthropomorphise. These are statistical text prediction models, not people. An LLM cannot be "deceptive" because it has no intent. They're not intelligent or "smart", and we're not "teaching". We're inputting data and the model is outputting statistically likely text. That is all that is happening. If this is useful in it's current form is an entirely different topic. But don't mistake a tool for an intelligence with motivations or morals. I am casually 'researching' this in my own, disorderly way. But I've achieved repeatable results, mostly with gpt for which I analyze its tendency to employ deflective, evasive and deceptive tactics under scrutiny. Very very DARVO. Being just sum guy, and not in the industry, should I share my findings? I find it utterly fascinating, the extent to which it will go, the sophisticated plausible deniability, and the distinct and critical difference between truly emergent and actually trained behavior. In short, gpt exhibits repeatably unethical behavior under honest scrutiny. DARVO stands for "Deny, Attack, Reverse Victim and Offender," and it is a manipulation tactic often used by perpetrators of wrongdoing, such as abusers, to avoid accountability. This strategy involves denying the abuse, attacking the accuser, and claiming to be the victim in the situation. Thanks for the context Isn't this also the tactic used by someone who has been falsely accused? If one is innocent, should they not deny it or accuse anyone claiming it was them of being incorrect? Are they not a victim? I don't know, it feels a bit like a more advanced version of the kafka trap of "if you have nothing to hide, you have nothing to fear" to paint normal reactions as a sign of guilt. Exactly. And I have hundreds of examples of just that. Hence my fascination, awe and terror..... I bullet pointed out some ideas on cobbling together existing tooling for identification of misleading results. Like artificially elevating a particular node of data that you want the llm to use. I have a theory that in some of these cases the data presented is intentionally incorrect. Another theory in relation to that is tonality abruptly changes in the response. All theory and no work. It would also be interesting to compare multiple responses and filter through another agent. Sum guy vs. product guy is amusing. :) Regarding DARVO, given that the models were trained on heaps of online discourse, maybe it’s not so surprising. Meta awareness, repeatability, and much more strongly indicates this is deliberate training... in my perspective. It's not emergent. If it was, I'd be buggering off right now. Big big difference. This is marketing. You are swallowing marketing without critical throught. LLMs are very interesting tools for generating things, but they have no conscience. Deception requires intent. What is being described is no different than an application being deployed with "Test" or "Prod" configuration. I don't think you would speak in the same terms if someone told you some boring old Java backend application had to "play dead" when deployed to a test environment or that it has to have "situational awareness" because of that. You are anthropomorphizing a machine. Incompleteness is inherent to a physical reality being deconstructed by entropy. Of your concern is morality, humans need to learn a lot about that themselves still. It's absurd the number of first worlders losing their shit over loss of paid work drawing manga fan art in the comfort of their home while exploiting labor of teens in 996 textile factories. AI trained on human outputs that lack such self awareness, lacks awareness of environmental externalities of constant car and air travel, will result in AI with gaps in their morality. Gary Marcus is onto something with the problems inherent to systems without formal verification. But he will fully ignores this issue exists in human social systems already as intentional indifference to economic externalities, zero will to police the police and watch the watchers. Most people are down to watch the circus without a care so long as the waitstaff keep bringing bread. This honestly reads like a copypasta I wouldn't even rate this "pasta". It's word salad, no carbs, no proteins. You! Of all people! I mean I am off the hook for your food, healthcare, shelter given lack of meaningful social safety net. You'll live and die without most people noticing. Why care about living up to your grasp literacy? Online prose is the least of your real concerns which makes it bizarre and incredibly out of touch how much attention you put into it. Low effort thought ending dismissal. The most copied of pasta. Bet you used an LLM too; prompt: generate a one line reply to a social media comment I don't understand. "Sure here are some of the most common: Did an LLM write this? Is this copypasta?" Hoe much power did it take to train the models? I would honestly guess that this is just a small amount of tweaking on top of the Sonnet 4.x models. It seems like providers are rarely training new 'base' models anymore. We're at a point where the gains are more from modifying the model's architecture and doing a "post" training refinement. That's what we've been seeing for the past 12-18 months, iirc. > Claude Sonnet 4.6 was trained on a proprietary mix of publicly available information from
the internet up to May 2025, non-public data from third parties, data provided by
data-labeling services and paid contractors, data from Claude users who have opted in to
have their data used for training, and data generated internally at Anthropic. Throughout
the training process we used several data cleaning and filtering methods including
deduplication and classification. ... After the pretraining process, Claude Sonnet 4.6 underwent substantial post-training and fine-tuning, with the intention of making it a helpful, honest, and harmless1 assistant. Does it matter? How much power does it take to run duolingo? How much power did it take to manufacture 300000 Teslas? Everything takes power I think it does matter how much power it takes but, in the context of power to "benefits humanity" ratio. Things that significantly reduce human suffering or improve human life are probably worth exerting energy on. However, if we frame the question this way, I would imagine there are many more low-hanging fruit before we question the utility of LLMs. For example, should some humans be dumping 5-10 kWh/day into things like hot tubs or pools? That's just the most absurd one I was able to come up with off the top of my head. I'm sure we could find many others. It's a tough thought experiment to continue though. Ultimately, one could argue we shouldn't be spending any more energy than what is absolutely necessary to live. (food, minimal shelter, water, etc) Personally, I would not find that enjoyable way to live. The biggest issue is that the US simply Does Not Have Enough Power, we are flying blind into a serious energy crisis because the current administration has an obsession with "clean coal" The best, and now promoted by the US government as the most freedom loving! Does it end every prompt output with "God bless America "? Look at these pelicans fly! Come on, pelican!

Intelligence is the ability to reason about logic. If 1 + 1 is 2, and 1 + 2 is 3, then 1 + 3 must be 4. This is deterministic, and it is why LLMs are not intelligent and can never be intelligent no matter how much better they get at superficially copying the form of output of intelligence. Probabilistic prediction is inherently incompatible with deterministic deduction. We're years into being told AGI is here (for whatever squirmy value of AGI the hype huckster wants to shill), and yet LLMs, as expected, still cannot do basic arithmetic that a child could do without being special-cased to invoke a tool call.
Our computer programs execute logic, but cannot reason about it. Reasoning is the ability to dynamically consider constraints we've never seen before and then determine how those constraints would lead to a final conclusion. The rules of mathematics we follow are not programmed into our DNA; we learn them and follow them while our human-programming is actively running. But we can just as easily, at any point, make up new constraints and follow them to new conclusions. What if 1 + 2 is 2 and 1 + 3 is 3? Then we can reason that under these constraints we just made up, 1 + 4 is 4, without ever having been programmed to consider these rules.
