AlphaProof Nexus is a research framework released by Google DeepMind (not a commercial product) that pairs the Gemini 3.1 Pro LLM with the Lean proof assistant to autonomously generate and machine-verify mathematical proofs. It uses a multi-tier agent design (four variants ranging from a basic LLM-compiler loop to evolutionary search with Elo rating) and can optionally call the earlier RL-based AlphaProof system as a subagent. According to the accompanying arXiv preprint (May 21, 2026), the system autonomously solved 9 of 353 open Erdős problems and 44 of 492 open OEIS conjectures, at an inference cost of a few hundred dollars per problem. All generated Lean proofs are publicly available on GitHub under the Apache 2.0 license.
