the theorem count just hit 722. openai published 722 ai-written math manuscripts on github on oct 6, covering hundreds of open problems with lean-checked proofs.
the peer review queue just became the bottleneck.
Context
OpenAI's community post of Oct 6, 2026 says the public openai/math repository holds 722 manuscripts organized into 372 related result families, with papers, supporting proof artifacts, Lean formalizations for many results and 10 abridged reasoning summaries. They come from an internal OpenAI model evaluated on open research problems.
An independent index lists 372 families across 17 areas of mathematics.
The 722 manuscripts and the Oct 6 date match OpenAI. The post says lean-checked proofs, but the independent index lists 162 papers whose main result OpenAI claims a Lean formalization for, so not all 722 are Lean-checked. How many open problems the manuscripts cover was not seen in the excerpts read, so unsupported here, not refuted.
'the peer review queue just became the bottleneck' is the author's opinion.
