What's this about?
An unreleased OpenAI model attempted about 4,000 open problems; selected output became 722 manuscripts in 372 related families. The repository includes version history, citations, some Lean proofs and ten abridged reasoning summaries.
What exactly is a Lean formalization?
Lean turns a proof into code checked step by step by a proof assistant. It can rule out logical gaps in the encoded claim, but does not by itself prove that a result is important, original or encoded correctly.
