GSO-Bench leaderboard
TL;DR

GSO-Bench is a coding benchmark tracked on BenchGecko. GitHub Star Optimization benchmark. Evaluates ability to understand and improve open-source projects to increase quality and adoption.

Level 1

GitHub Star Optimization benchmark. Evaluates ability to understand and improve open-source projects to increase quality and adoption.

Level 2

Scores are reported (%, maximum 100); higher is better. BenchGecko collects GSO-Bench scores from Epoch AI and refreshes them daily; the leaderboard on this page shows the current top models.

Level 3

Compare models only on the same benchmark version and settings. A benchmark separates models well while scores are spread out; when top models bunch together near the maximum, it stops telling them apart.
