Results of our jailbreaking challenge: After 5 days, >300,000 messages, and est. 3,700 collective hours our system got broken. In the end 4 users passed all levels, 1 found a universal jailbreak. We’re paying $55k in total to the winners. Thanks to everyone who participated!

First came pre-training scaling; then came inference-time scaling. Now comes judge-time scaling. Despite progress in AI through scaled inference-time compute, AI remains unreliable in open-ended, non-verifiable domains. The key limitation is not generation—it is evaluation.

.Caido and HackerOne are collaborating on a plugin that streamlines the H1 submission process. We’re envisioning a plugin that gives a simple UI to combine evidence that serves as the foundation of a report and removes most of the writing burden. Link in the comments.

We're launching a new bug bounty initiative to stress-test an updated version of our anti-jailbreaking system before it’s publicly deployed. The program, in partnership with HackerOne, runs through Sunday.
