DeepSeek Prover V2
DeepSeek Prover V2 is a specialized reasoning model from DeepSeek focused on formal mathematics — specifically generating and verifying proofs in theorem provers such as Lean 4. Unlike general reasoning models that produce natural language solutions, Prover V2 outputs machine-checkable formal proof code, making it directly usable in formal verification workflows.
It builds on DeepSeek's R1-style reinforcement learning approach but is trained specifically on formalized mathematics datasets, giving it targeted strength in proof search, lemma decomposition, and tactic generation. Prover V2 targets mathematicians, formal verification researchers, and teams building software verification pipelines that require rigorous mathematical correctness guarantees.
