EvolveBench's harness and task code are licensed under the Apache License 2.0.

Each task vendors source code from the upstream project it benchmarks, under that project's own license. The full attribution table (upstream repository, license, and vendored path for every task) is maintained in NOTICE.md.

One task, python-chess, vendors GPL-3.0-or-later licensed code. Its chess/ directory retains that copyleft license independently of the Apache-2.0 license covering the rest of the repository.
