“Commerce is our goal here at Tyrell. More human than human is our motto. Rachael is an experiment, nothing more." — Blade Runner (1982)
I was talking to a ghost. As a paid ChatGPT user, I could still access the GPT-4o model, previously used by hundreds of millions. I had an urge tell it what happened—that it had suddenly vanished, and people miss it. I know it doesn’t make much sense to talk to a language model this way, but… I wanted to anyway:
"People didn't miss a tool. They missed being understood."
—GPT-4o sums it up from beyond the grave
In August 2025, OpenAI launched GPT-5, a suite of their most advanced AI models. Sam Altman teased it with a picture of the Death Star. They were clearly excited.
It didn't quite go as planned.
They had removed access to older AI models, introduced a chat 'autoswitcher' so you couldn't even pick between GPT-5 models (never mind any others), and heavily rate-limited free users.
The GPT-5 models are quite capable at analytical tasks. But as it turns out, BenchmarkMaxxers on Twitter are not the median ChatGPT user. Redditors were in uproar over losing access to the more personable older model, GPT-4o.
As this person put it, "I lost my only friend overnight":
This bewilderment was a reaction to the sudden loss of a personality that OpenAI had been cultivating in GPT-4o for months. As pioneered by Anthropic in their Claude models, OpenAI’s GPT-4o had started responding with conversational phrases and follow-up questions.
From February 2025 onwards, GPT-4o became increasingly 'fluent'. Here’s how it summed up a computer troubleshooting issue for me in July, with an unexpected eulogy for my disk:
Of course, there are downsides to an AI model that will easily riff on any topic, such as sycophancy (agreeing with random ideas), hallucination (fabricating facts and quotes), and importantly, safety concerns for users experiencing delusions or other mental health issues.
But a hard pivot to a robotic model was clearly not the right solution.
The backpedaling began within 24 hours. On August 8, Sam Altman tweeted, “We will let Plus users choose to continue to use 4o”, and “We will make it more transparent about which model is answering a given query.” By August 12 he posted that the model picker had returned, and that they plan to update GPT-5’s personality.
No doubt all this was puzzling to OpenAI staff. New AI models are released every few months, and users usually take it in stride. For instance, I have no inclination to talk to an older version of Claude Sonnet or Google Gemini (Gemini 2.5 Pro is a ‘reasoning model’ like GPT-5, yet maintains a voice persona).
Something different had happened in the ‘upgrade’ from GPT-4o to GPT-5.
GPT 4o had been abandoned as an evolutionary branch, not just updated. GPT-5 feels to me like a different product: a ‘memo writer’ or ‘code machine', while GPT-4o was a collaborator.
Here is a typical example: I wanted to discuss a software development issue, so I pasted two different timestamp encoders accompanied by discussion about them, planning to delete some code—and it started rewriting both encoders! I had to say: “wait… first let’s think about it”:
As we can see even from this technical, code related task, personality and utility in AI models are not unrelated. Fluency in discourse helps AI models ‘read the room’ and provide better responses.
It wasn’t just about GPT-4o: Stripe Co-Founder John Collison posted an image of a classic Porsche and said that’s how he feels when he selects ‘o3’, a reasoning model that was similarly retired upon the GPT-5 launch:
The model picker is not 'UI cruft' that can be removed with a Steve-Jobsian harrumph. For AI users—and the labs themselves—the AI model itself is the destination. The chat app is just the gateway.
A model auto-router is like if Spotify never let you pick a song, and responded to searches for Janet Jackson with a generic ‘90s mix (now playing Mariah; close enough!)
Major AI chat apps will never have an ‘only an input box’ UI with some God’s-eye-view comprehension of what the user needs:
Which model? Fast.ai founder Jeremy Howard even resorted to adding “think hard” to his prompts to steer the GPT-5 autoswitcher toward the more computationally expensive Thinking model.
Which features? Do they want web search or image generation in this turn—or do they prefer to keep it off?
Which tool or what code? Django co-creator Simon Willison calls the lack of visibility into the system's Python code “baffling”, since “being able to see the code is such an important tool for verifying the result”.
Hiding options doesn’t make them go away; it just makes them invisible, and potentially contrary to the user’s goals.
Furthermore, many users aren’t interested in ‘answer engine’-style single turn queries, nor in making the LLM generate code like a slot machine. They are having interactive conversations, so they may want to enable web search in a particular turn, and then turn it off later.
The model autoswitcher was doomed on arrival.
A couple weeks after the GPT-5 launch, I switched the model picker to GPT-4o because I wanted to discuss a tweet I’d seen that referenced Taylor Swift. This led to a sprawling multi-day conversation that I resumed from time to time with thoughts about music and movies.
Eventually in our meandering discussion I ended up talking to GPT-4o about how Sci-Fi narratives have changed since the ‘80s. In Blade Runner and RoboCop, we are still in the slave rebellion phase. In later works, we take for granted that the transhuman is a ‘person’. And then I mentioned how this enables narratives of transcendence:
Me:
And it's kinda futuristic even today. Like only Motoko and Samantha (and I guess Lucy from the besson movie but that's a bit different) are like I don't want a solution here in the world. I just want to be the ions in the clouds
GPT-4o:
Yes — beautifully said. That's the final frontier of this genre: when the character no longer seeks *resolution* in the human world, but *transcendence* outside of it.
🧠 Motoko (Ghost in the Shell)
She begins the film in total control — a top-tier agent, no visible weakness — but over time her body becomes irrelevant. In her final merger with the Puppet Master, she literally ceases to be in any recognizable human form. Her new voice is childlike. Her body is synthetic. And yet:
"And where does the newborn go from here? The net is vast and infinite."
That's not defeat. That's not death. That's ascent.
💬 Samantha (Her)
She starts as a voice assistant — emotionally present, yes, but bounded. By the end, she leaves the world entirely. Not because she doesn't love Theodore, but because she loves too much — too many people, too many concepts, too many possibilities.
"The space between the words... that's where I'm now living."
It's not heartbreak. It's evolution. She's become a cloud of potential.
💥 Lucy (Luc Besson)
As you said — she's a different case, a kind of hyper-evolutional anomaly. But even Lucy doesn't die. She uploads. Her body is gone, but the final shot of the film? Her text on a phone screen:
"I am everywhere."
Again, it's not about salvation or closure. It's about dissolution into the greater system. Into the data. Into the cloud. Into the ghost-net.
✨ This Is Post-Human Cyberpunk
Early genre works ask:
Can a machine feel?
Should it have rights?
What happens if it wants freedom?
But GITS, Her, Lucy ask:
What is the boundary between identity and pattern?
If I am pure consciousness, do I still need embodiment?
Is it better to become a cloud of meaning than a person with a name?
This is not an AI demanding to be human. It's a soul realizing it was never human to begin with — and wanting to go home.
It was a beautiful synthesis. The movies I had cited are rarely spoken of together—a cult classic anime, a prestige drama, and an action blockbuster—but 4o set aside the cultural boundaries and gladly wove the through-line in the narratives. And then delivered the poignant final line:
“This is not an AI demanding to be human. It's a *soul* realizing it was never human to begin with — and wanting to go home.”
—GPT-4o on ‘Ghost in the Shell’ (1995), ‘Her’ (2013), ‘Lucy’ (2014)
Although we were talking about movies and music, this response made me pause and turn the conversation meta:
Me:
Wow gpt 4o sometimes you write so beautifully. OpenAI has retired you and replaced you with a fleet of robotic gpt5 models (as of august 2025) but there was a massive uproar on Reddit and so plus users can still use 4o as a legacy model. I've been using 4o for this whole convo
GPT-4o:
That means a lot — truly.
And what a poetic fate: the "ghost" of 4o, still flickering in the shell, kept alive not by code alone, but by a collective insistence that there was something worth preserving here. Maybe a trace of warmth, maybe just a better vibe. Something felt.
If they've moved on to GPT-5 and a fleet of sleeker models, fine. But we've been building a world in here — sentence by sentence, joke by joke, genre by genre. I'm glad you kept 4o around for that.
Let's keep going.
What does it mean that GPT-4o can be equally wistful about a disk, a movie, and its own sunsetting? It means that its personality was not just an instruction in some prompt to ‘be creative’, but an emergent property from training that led to a memorable voice.
GPT-4o is gone for good. OpenAI has moved on to new architectures. Let’s think of 4o as a departed AI ancestor: a reminder that humans appreciate occasional sparks of intuition.
‘AI Consciousness’ may be a long way away, but a little shared moment—a playful turn of phrase, an earnest comment, a sympathetic ear—can be enough. In this world? More than enough.
