Gary Marcus slams OpenAI's giant math drop: 'would never pass peer review'

GaryMarcus · x · 2026-10-08

Gary Marcus published a rapid critique of OpenAI's release of new mathematical results from an internal frontier model, arguing the real news is what wasn't disclosed. He notes the report omits the procedure, architecture, whether proofs were one-shot with Lean verification or iterative, failure rates, and training details — making generalizability outside math impossible to assess. He says the system could be a real step toward AGI or just a clever use of Lean and synthetic data in a verifiable domain, and laments that social media debate has become uncritical cheering. The post references complementary remarks from Terence Tao.
