As part of our commitment to safety at the frontier, we conduct rigorous testing of our models' cyber offense capabilities. For Claude Opus 4 and Claude Sonnet 4, we partnered with Pattern Labs to conduct an in-depth evaluation ranging from standalone capture the flag(CTF) challenges to complex network environment simulations. The results reveal significant progress: Opus demonstrated markedly improved ability to think flexibly and adapt its approach to challenges instead of persisting with failed, unchanging approaches. Moreover, the model demonstrated significant improvement in vulnerability identification and executing complex multi-step attack chains, consistently succeeding where previous models failed. However, important limitations remain, particularly with maintaining coherent, long-horizon plans and goals if presented with unexpected obstacles.
