Proof checkers drive recursive improvement in AlphaProof and DeepSeekMath-V2
Overview
The Sequence explains how AlphaProof, Goedel-Prover-V2 and DeepSeekMath-V2 use a generator paired with a checker to choose which proofs become training data.
According to the article, Lean's kernel makes verifying a proof easier than finding one, and AlphaProof turns its search attempts into training material, including test-time reinforcement learning.
The article also notes a limit: a checker can confirm a proof is valid but cannot confirm that the stated theorem is the one intended.

AIThe Sequence examines how AlphaProof, Goedel-Prover-V2, and DeepSeekMath-V2 use a generator and a checker to decide which proofs become training material. It describes how Lean's kernel makes checking easier than finding proofs, and how AlphaProof turns exploration into training, including test-time reinforcement learning. The piece also notes that a checker cannot confirm whether a stated theorem is the one intended.
