FeatureBench - Passed Rate: leaderboard
Metric: Passed rate (%): per task, the share of executed fail-to-pass tests that pass, averaged over tasks (partial credit), on the 200-task FeatureBench Full set (feature-level development tasks traced from unit tests in 24 Python repositories: 166 extending an existing codebase and 34 implementing the feature from scratch, each with a callable interface to implement, fail-to-pass and pass-to-pass tests, internet access without browser tools and cheating checks); each model run in the named agent harness (OpenHands up to 500 steps); higher is better.
