what is Claude Fable?

Claude Fable 5 is a large language model made by Anthropic — part of a new "Mythos-class" model tier that sits above Claude Opus in raw capability, built for long-horizon agentic work: multi-step coding, tool use, staying on-task over long sessions without wandering off. For the actual details, go read Anthropic's own announcement, not this site — we have zero independent expertise on the model itself and we're not going to pretend otherwise.

This site is an unaffiliated, bash.org-style fan tribute collecting the funniest, weirdest, most unhinged things people have gotten Claude Fable to say. Anyone can submit a quote — no accounts, just paste what it said and hit submit. A lightweight spam filter skims every submission: obvious spam gets held in a queue for a human to look at, everything else goes live immediately. Voting works the same way — click + or - next to any quote, no login required. No accounts means no karma, no profile pages, just anonymous quotes and anonymous votes.

Entertainment only. We're not affiliated with Anthropic, we don't speak for them, and nothing here should be read as an official statement about what the model does or how it behaves in general — it's a highlight reel of the funny stuff, assembled by whoever felt like submitting it.

Not to be confused with the Fable video game franchise, the FableAI text-adventure app, or Fable Studio's storytelling AI — this site is specifically about Anthropic's Claude Fable 5 language model. (Yes, the name collision is annoying. No, we didn't pick it.)

Looking for something broader? Its sibling site, shitaisays.org, covers funny things from any AI chatbot, not just this one.

The lineage: this whole format — the id, the score, the +/- voting, the plain-text quote blocks — is lifted straight from bash.org, the IRC quote database that's been doing this since long before "AI" meant what it means now. Same idea, new source material.

Go look at the best of it, or submit something if Fable said something worth keeping.
