OpenAI has developed a neural theorem prover for the Lean formal proof assistant that can solve challenging high-school olympiad math problems. The system utilizes a language model to discover proofs, iteratively improving its performance by using newly found proofs as training data. This approach achieved a new state-of-the-art on the miniF2F benchmark, outperforming previous methods. AI
