How we rank coding models

We average two benchmarks:

  • SWE-bench Verified: real GitHub issues from popular open-source repos. It tests autonomous software engineering: read the issue, write a fix, pass the test suite.
  • LiveCodeBench: competitive programming problems from LeetCode, Codeforces and AtCoder, collected after model training cutoffs to limit contamination.

Each score links to its source on the benchmarks leaderboard; scores from independent evaluators (Vals AI, Artificial Analysis) and from developers' own announcements are both used, and developers' figures are often higher. Rankings update as new scores are added.
