BREAKING: OpenAI’s solution to Navier–Stokes does not match its Lean verification.
The most important article to read today is not one of OpenAI’s 700 AI-generated math papers.
It is this other paper, making a deep and worrying point:
A Lean-verified proof does not automatically validate the proof written in natural language, nor does it mean that the formal statement captures the intended theorem.
During translation, an AI can change an assumption, weaken a statement, or replace the argument entirely.
It can hallucinate another theorem.
Lean correctly verifies the result.
But the proved result may no longer be what the paper claims.
This is a general problem. Things get spicy when the authors examine OpenAI’s proposed Navier–Stokes solution.
They identify at least two mismatches between the written intermediate results and their Lean counterparts:
One estimate claims that four additional input derivatives suffice. The Lean version requires five: a weaker result.
A pressure-flux estimate is obtained through a different bound, and proved through a different argument.
It is not clear whether these mismatches invalidate the entire proof.
But they raise an important issue.
OpenAI is flooding us with claimed revolutionary breakthroughs. Yet nobody knows whether the proofs are correct or whether they prove what they claim to be proving.
Epistemia at scale.

@MahdiKahou Very well said. And also this would be hard to do so in macro with so many disagreements on the modeling choice. AI is useful for calibration in macro but it is not good at coming up with its own theoretical model. There are many subtleties in a macro model.
@auyonymous@_cingraham It’s a bit offensive, IMO, but I’m glad you’re seeing the funny side of it. He was probably just making a poor attempt at trolling you
@40yoap@wwwojtekk Someone should use AI to work out all the solutions to Rudin's textbook, and publish a solutions manual. Same goes for the MWG textbook in Micro.
@aledinola@40yoap@wwwojtekk Oh nvm the Jehle and Reny solutions were handwritten by someone.
The MWG solutions were prepared by Hara, Segal, and Tadelis. But yes, they are not in a nice PDF format with Latex typesetting.
@aledinola@40yoap@wwwojtekk There used to be an MWG solution online, and it may still exist. However, it was handwritten and scanned by someone (or a group of people). I would prefer it if it were available as a proper PDF with Latex typesetting.
@gguillaumeblanc Btw I would be wary of uploading a submitted manuscript to Pangram, as this may also go against a journal's LLM policies given that one has accepted to review the paper. Uploading a working paper may be fine, but I'm not 100% certain.
