A behavioral audit is a structured, often periodic review of how a model is actually behaving — typically run before a major launch, after a significant update, or on a regular schedule as part of governance. Unlike routine evaluation, audits tend to be broader and more deliberate: they might include expert human review of samples across many behavioral dimensions, testing against adversarial scenarios, and a comparison of actual behavior against the written behavioral specification. Audits produce a record that can be shared with stakeholders and used to demonstrate accountability. For behavior architects, behavioral audits are both a quality tool and a governance mechanism — they create a documented checkpoint that the model meets its stated behavioral standards at a given point in time.
