Open-Sourcing Lean Formalized Proofs
__eknight__ · x · 2026-07-11
The author announced they have open-sourced the Lean formalized version of a proof, with the formalization work completed by the creator of GPT 5.6 Sol.
Additionally, the post provided:
- A link to the main proof text
- The complete prompt used to generate the proof
- The open-source repository for the formalized implementation
The key highlight is the availability of a machine-checkable Lean formalization alongside the natural language proof, making it easy to reproduce and review.
