Petri 2.0 is Anthropic’s updated automated behavioral auditing framework for LLMs. It runs large suites of realistic, model-generated multi-turn scenarios and adds eval-awareness mitigations such as realism classifiers and seed refinements so models cannot easily detect they are being tested. The release also expands the scenario library and reports new safety and alignment comparisons across recent frontier models.
