Consensus answer
No, Mistral did not secretly release and then remove an AI model called "Le Chaton Fat."
"Le Chaton Fat" is entirely a viral internet meme and a satirical hoax.consensnumerama The name itself is a playful pun combining "Le Chat"—the name of Mistral's actual chatbot interface—with the phrase "fat kitten".consensx
The rumor that a model was "removed hours later" originated from a now-deleted joke announcement teasing a fictional model.diggdigg Users on social media platforms like X and Reddit circulated screenshots with increasingly absurd, fabricated specifications, claiming the AI was a 24- to 30-trillion-parameter "Mixture of Experts" model featuring a 1-million token context window and native LaTeX rendering.consensdiggreddit
There is no evidence of any actual project or software behind the joke.digg Mistral never developed, released, or suspended a model by this name, and the company's real, documented model lineup remains completely unrelated to the meme.consensmistral

“Mistral briefly posted a joke announcement for a fictional 24-trillion-parameter model and then deleted it”
The post was not from Mistral's official account.

“Mistral AI's official channels had no such post; it was a shitpost/parody by accounts that got mistaken for real.”
How to verify: Check if the original joke announcement was posted by Mistral's official social media account or by a third-party parody account.
