Unverified: OpenAI's Tibo Posts Only the Words Le GPT Fat, and Followers Read It as a Teaser for a Bigger GPT 6.2 Astra Model

Context

Tibo (@thsottiaux) is on OpenAI's team and has posted about upcoming models before, including GPT 6 Astra and GPT 6.1 Terra coming to Dots, a story in the Nov 2 deck. His new post contains only three words and no link, image or explanation. OpenAI has not announced any model called GPT Fat.

Deep dive

Tibo (@thsottiaux) posted the words Le GPT Fat just after midnight ET on Nov 3, with no link, image or explanation. Within about four hours the post had nearly 700,000 views, more than 5,000 likes and close to 1,000 replies.

The post itself makes no claim. Quote posts and replies filled in the gap with guesses. Several quote posts read it as a hint that a GPT 6.2 Astra model is coming and that it will be a larger, heavier model. Others simply joked about the phrase. None of these readings come from OpenAI, and none of the accounts making them cited a source inside the company.

The interest fits a busy stretch for OpenAI news on X. On Nov 2 Tibo said GPT 6 Astra and GPT 6.1 Terra were coming to Dots, and a clip shared that day showed Sam Altman saying the model that solved Navier Stokes is the next GPT. Both stories are in the Nov 2 deck.

Until OpenAI says more, the safest reading is that a member of its team posted a teaser that people strongly want to be a model announcement. This story is labeled unverified for that reason and will be updated if a release follows.

What to expect next

Watch OpenAI's official accounts and Tibo's next posts for any announcement that explains the phrase. If a new Astra model does arrive, the key questions are its size, price and how it compares with GPT 6 Astra on public benchmarks. If nothing follows in the next few days, the post will most likely be remembered as a joke that happened to go viral.
