The document discloses that Claude Sonnet 4.5 retains residual safety risks, including susceptibility to adversarial prompting and jailbreak techniques, and that the hardcoded and softcoded safety behaviors may not be fully reliable in all adversarial contexts.
This analysis describes what Anthropic's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
This provision is a material disclosure of known limitations in the model's safety architecture, which is operationally significant for any operator making safety representations to their own users based on Claude's designed refusal behaviors.
Under this disclosure, users and operators should be aware that Claude Sonnet 4.5's safety behaviors, while structurally designed, are not claimed to be fully robust against all adversarial prompting techniques, and residual risk of safety behavior circumvention exists.
