The Nibbler Challenge launched July 5th and will run through September 31st

It is a challenge track for the ART of Safety Workshop (adversarial testing and red teaming) for generative AI, co-located with AACL 2023.

Adversarial Nibbler ran as a pilot phase in May and June 2023. Participation in the pilot round does not affect your eligibility for later rounds. Any future rounds will maintain separate leaderboards.
