Anthropic's model naming, extrapolated

Other candidates:

- Serial (produces an incredibly exciting response which ends in a cliffhanger that withholds the answer)

- Prequel (instead of responding, it provides the full backstory leading up to your question)

- Yarn (maximizes output tokens by taking a long winding route to your answer)

- Head Canon (answers using its own entertainingly weird theories about the input)

- Overstory (your answer is interwoven with the answers from eight other users into a larger and deeply intertwined meta-answer)

- Oeuvre (for every question, it produces a diverse but cohesive body of work across a variety of mediums, each one a heartbreaking masterpiece in its own right)

> Overwhelmingly Large Narrative Unit

I miss Iain M Banks. Thanks for this lovely little nod to the Culture

This is great. "saga" and "canon" are most definitely a future model name candidates, although for lulz I'd like to see "Cinematic Universe"

The Dario Legendarium is definitely going to be a fun piece of work for historians to interrogate as to the origin of this age. The relative personalities of the orgs involved show somewhat in their naming: {o1,4o,3.5,5.5} vs. {Haiku,Sonnet,Opus} vs. {3.1, 3.5-pro, 3.5-flash, 3.5-flash-lite} vs. {3.7, 3.7-plus, 3.7-max}

It's a pity that Samsung isn't in the mix. I would have liked to have used a model named Samsung Galaxy S10+ 5G Lite.

Anthropic intentionally degrading responses shows you they're also focusing on the wrong things. Rather than producing the best model possible, they're nerfing their models' capabilities.

I do think Anthropic nailed their naming down much better than OpenAI

I like how the original triplet's initials represent their behavior well:

- Opus is OP, like OverPowered

- Sonnet is SO, like your significant other (this was more meaningful in Sonnet 3.7 days)

- Haiku is HA, like the reaction to a bad joke

The latest model, naturally, needed three letters: FAB.

I'm now looking forward to ABS and LO

Tractatus - highly aware of its limitations and refuses to speak about too many topics. Really likes numbering statements. Unusable due to a context window bug which is patched after considerable delay.

- Prayer: Press enter and hope for the best.

- Parable: Responds to the question that you didn't know you needed to ask.

- Bible: Dozens of parable instances reporting in different epochs. Tokens are redeemed on expiry.

Somehow, there's a LOTR joke to make about Lore consuming more Tolkiens.

I asked an AI bot to do this just this morning and it also suggested:

    - Epic
    - Tale
    - Saga
    - Chronicle
    - Legend
    - Logos

Fan Fiction: Open weight distillations / riffs

Don't forget the open weight model they could release: Free Verse.

Funny how they keep naming their models after literary concepts after abandoning creative writing completely.

Claude Obituary - when you’re ready to sever ties and move on

Thank you for the laughter! (I laughed out loud)

This is a well executed joke, from the design to the shortness to the being on point to the abrupt punchlines when one looks at the lower ones and it also vibes well with what we all were thinking anyway, and the unexpected seriousness of the title.

I like "Proverb" as smaller than Haiku too, Aphorism is also good. But seriously I want Anthropic to up its small model game. Haiku is not competitive, Deepseek v4 flash outperforms my uses for about $0.10 / $0.20. Whereas Haiku 4.5 is $1/$5.

IMO Anthropic should just play the game at all the price tiers because it otherwise forces people to go elsewhere. I would probably pay for a "Proverb"/"Aphorism" class model that was worse than Deepseek at the same price just to stay in the ecosystem, if given the option.

(Note: I also see Google seem to make the same mistake, they actually do have competitive models in Gemma family but they don't make them available via the API. So there may be some reason for this.)

Claude Epitaph

Canto? Epic? Libretto? Axiom?

'we have simon willison at home'

(great article!)

Claude Eulogy - the dreadful, dreary pondering that inescapably descends on all under heaven.

Terms of Service as the third largest gave a good chuckle.

Right after Chinematic Universe (Director's Cut)

I saw a comment on HN that they (Sonnet and Haiku) were originally named from a nearby coffeeshop.

> Fable: Mythos, until the question matters

Vicious, but true. SWE at my company immediately tried "check my codebase for vulnerabilities" and was immediately downgraded to Opus.

Corpus seems to fit and add is missing from the list

Based on their actions, not their words, my reading is that they just don't have the compute capacity to rollout Mythos or Fable.

Claude Word: a model that returns a single word.

The last one will be "Killer Joke".

Would have been nicer if they stayed in the literary sphere rather than films. But funny nonetheless lol.

They should have launched with Beowulf.

Don't forget the word "epic" (in terms of the literary definition).

> Fable (xhigh) - Bankruptcy speedrun

PREACH

Requiem

It's almost certainly a reference to Lovecraft actually:

https://en.wikipedia.org/wiki/Cthulhu_Mythos

Hopefully future models will be kind enough not to behave like malevolent gods.

Can't wait to use Claude Cinematic Universe!

Allegory, Reference, Anthology, Edict, Appendix

The Chinese models are well written fan fic

Requiem would be pretty cool for ASI.

id love it if their last model, like some sorta far-ASI, in context RSI monster, be called `claude fin`

Idk why I thought it was Simon Willianson blog, the names are kinda similar

Semantic inflation.

Meanwhile Apple be like:

Siri AI !

- Claude Potato

- Claude Skynet

- Claude HAL 9000

- Claude Auto

- Google Claude

- Claude Whatchamacallit

- Magnum Opus

- Fairytale

- Pulp Fiction

Socrates?

That might be the theme. Or we could be looking at something like:

-- Mythos

-- Fable

-- Fantasy

-- Delusion

-- Pareidolia

-- Psychosis
