ProofForge

ProofForge is an AI-powered formal verification pipeline that decomposes mathematical problems into lemmas, then automatically proves and formalizes them in Lean 4, a theorem prover. Proofs verified by the Lean kernel ensure correctness, enabling machine-verified proofs in formal mathematics such as Erdős problems. Several contributions from ProofForge have been merged into Google DeepMind's formal-conjectures repository.
