After seeing so many broken defenses (a bunch by myself) you get a bit paranoid.
So I kept pushing for more attack evals and our results are only stronger for it :)
Still, no guarantee that a cleverer attack won't come up, but I know that we exhausted our ideas (and budget...)
4/ We tested it with RL-optimized adversarial suffixes, an automated red-teaming agent, and 144 hours of expert human red-teaming, and we report the worst-case results. A case is counted as a successful attack if any of the three methods works.
