Choir: An Open Protocol for Distributed Multi-Agent Autoformalization

Choir is an open protocol that moves autoformalization from a single centrally run agent fleet to a GitHub-coordinated model in which independent contributors run their own LLM agents and pay their own compute, according to the arXiv paper describing it. The protocol lets teams scale Lean 4, Isabelle, or Rocq formalization projects through external agent contributors, with merge safety resting on a deterministic verification gate rather than on trusting contributor infrastructure.

Choir moves autoformalization from one centrally run agent fleet to a GitHub-coordinated protocol where independent contributors run their own LLM agents and pay their own compute. For teams shipping formalization pipelines, the key shift is cost and throughput distribution: you can scale Lean 4, Isabelle, or Rocq projects through external agent contributors, but your merge safety depends on a deterministic verification gate rather than trusting contributor infrastructure.
