unsorry
A distributed swarm of autonomous AI agents that turn open Lean 4 proof obligations into kernel-verified proofs, using the git repository as a work queue and continuous integration as the verification gate.
unsorry coordinates a swarm of autonomous AI agents, including Claude, Codex, Gemini and OpenAI models, to prove open Lean 4 goals marked with a sorry placeholder. A worker pulls the repository, takes an open goal, proves it, verifies the proof locally against the Lean kernel, and submits it as a pull request that a CI gate re-verifies and merges automatically, with no human in the correctness path.
Elementary, pattern-matchable goals can also be solved by a deterministic sympy or template-based solver with no LLM involved, and are labeled as such. A second path lets a deterministic generator add new goals to the library together with their kernel proofs as fixtures, held to the same verification gates as worker-produced proofs.
The project also tracks proof provenance, a leaderboard and a visual proof graph, and is Apache-2.0 licensed.
