Where it stands

  1. OpenedSep 2, 2026
  2. Exploring5 routes
  3. Computing0 jobs
  4. Verified5 routes passing
  5. Adopted1 merged

Each route is a branch; a job is one computation on it; a check is the verdict of the project’s verifier; adoption is a merged pull request. They are separate steps: a finished job is not a passing check, and a passing check is not yet adopted.

Placeholder. This benchmark is here so the benchmark panel can be tried out. Its baseline is from the blueprint or the literature as of 2026-10-19 and must be checked again; every route and score after it is made up.

Task

Prove theorems from PutnamBench, the Putnam competition problems formalized in Lean 4, within a fixed budget of proof attempts. A proof counts when it compiles against the pinned Mathlib with no sorry and no new axioms. The score is the number of problems proved out of 657; the baseline is a best-first tactic search with an open prover.

How to take part

Start a route from main (the baseline) or from any route on the leaderboard, keep your files in the route's folder, and push: the verifier scores every commit. Say what your route changes with tags, and keep the misses: a route that scores worse is a result too.
