Claude Formalizes Fermat's Last Theorem in Lean
Anthropic recently completed a massive research task. An internal model worked for 11 days to formalize Fermat's Last Theorem using the Lean 4 proof language.
This is not a new mathematical discovery. Andrew Wiles proved this theorem in 1995. What Anthropic did was translate that existing proof into code. This allows a computer to check every logical step with total certainty.
The scale of this project is massive: • The model produced 13 million lines of Lean code. • It proved 30,300 intermediate theorems. • It used nearly 6 billion output tokens.
The model worked mostly on its own. Humans only gave occasional high level directions. The process finished in the middle of the night while no one was watching. The system logged the success automatically.
Two important things to note:
- This model is an internal research tool. You cannot access it via API yet. It is not the same as the Claude models you use today.
- The real value for developers lies in the coordination layer called Prove2Me.
Prove2Me is an open source tool. It uses a dependency graph to manage tasks. Instead of a simple checklist, it creates a map of how proofs connect to one another.
This structure solves two major problems for agent workflows:
- It prevents multiple agents from doing the same work.
- It gives agents a shared memory so they do not forget the main goal.
Most agent workflows fail because they lose track of context over time. Using a shared, external graph instead of a long chat window keeps the task on track.
You should study the Prove2Me architecture if you build agent workflows. Even if you do not use Anthropic's research models, the way they coordinate tasks is a blueprint for long horizon work.
