About Codabench

Codabench is a free, open-source platform for running AI benchmarks and competitions. Organizers set up tasks, datasets and scoring programs, and participants submit code or results. Each submission is evaluated automatically and reproducibly inside a Docker image, and results appear on live leaderboards.

Submissions run on Codabench's shared compute workers by default. Organizers who need more power, such as GPUs, can connect their own workers through a private queue and keep full control over their hardware and data.
