On November 1 @chetaslua pointed to MLflow’s Azure model list as proof that Fable 5.5 “already hit Azure”. MLflow’s catalog bot added claude-fable-5-5 there on October 14 at 01:11 UTC (pull request 26724), while LiteLLM still listed it, with the same $10 / $50 and 1M context; nobody has removed it since.

Leak@chetaslua: a short video “one-shotted” in pure code by Fable 5.5Predictedauthor claim · unverified
About 1.6 million views when we read it. Before it, @Hesamation posted SVGs as Fable 5.5 output on October 31 and @chetaslua a one-shot web page on November 1; @kimmonismus calls the video “most likely the latest Fable 5.5 checkpoint”. The check the post offers is a question only a model with newer knowledge can answer: that shows a newer model answered, not which one. Outputs, not a release.

Ranked newest first for now; ranking by reach (the original post’s view count, recorded once with its date) starts when the reach field is filled. A screenshot, a routing test or a catalog row is not a release; an announcement from Anthropic, a model ID in the docs or a price is.

Questions about Fable 5.2
When is Fable 5.5 coming out?
It already has, as Fable 5.2, on November 9, 2026. “Fable 5.5” was the rumored name; Anthropic’s docs list no model by that name.
How do I get Fable 5.5?
Pick Fable 5.2 in the model picker on a paid Claude plan, or call claude-fable-5-2 on the API. Claude Free has no Fable models.
How much does it cost?
$8 input and $40 output per million tokens on the API. On Max and Ultra it is included up to 50% of the weekly limit; Pro has it on the plan through November 16, 2026, then pays with usage credits.
What if Fable 5.2 isn’t in my model list?
Check three things: Claude Free has no Fable models, Claude Code needs version 2.1.321 or later, and standard Enterprise seats need usage credits if the organization enables Fable.
What do the labels on the claims mean?
“Official” is Anthropic’s own page. “Our check” is something we looked up ourselves, with the link. “Author claim · unverified” is everything else: a post, a report or a listing we can link to but cannot confirm. Dates of X posts are read from the post IDs; “seen in search results only” means we read the post’s text in a search result and did not open it.
Were these works really made with this model?
That is the author’s claim. We cannot see which model actually ran, so every card carries an “author’s claim” line, and we say when an author works for the model’s maker.
I made one of these. Can I have it removed?
Yes. Email support@fable5.app with the link and we take it down within two working days.
