Answer.
Under M-25-21 an AI use is high-impact when its output serves as a principal basis for decisions or actions that have a legal, material, binding, or safety-relevant effect on rights or access to benefits — for example eligibility, medical, or safety determinations. The memo lists presumed categories and an agency Chief AI Officer makes the final call. Planisphere does not adjudicate that classification; once a use is designated high-impact, it measures the model's behaviour against a fixed probe set so the pre-deployment-testing and monitoring obligations have evidence behind them.
