Dear Codalab users,
As announced early last year, the CodaLab instance has been phased out for hosting new competitions and for handling submissions on existing competitions. As of September 2025, the creation of new competitions has been disabled. Submissions processing has now been fully stopped as of January 20th, 2026.
If you are a competition organizer and would like to continue accepting submissions for your competition, you can migrate it to CodaBench, which is now our main and actively supported platform. CodaBench supports CodaLab bundles and provides equivalent—and extended—functionality: How-to-transition-from-CodaLab-to-Codabench/
All existing competitions on codalab.lisn.fr remain available in read-only mode for consultation and for downloading datasets, resources, and competition bundle dumps.
If you encounter any difficulties during the migration process or have questions regarding the transition, please do not hesitate to contact us. We are happy to assist you in making this transition as smooth as possible.
