Description
Institutional pause instituted for the first time in Anthropic's history before widespread internal use of an early Mythos Preview version. Explicit rationale in system card: 'to gain assurance against the model causing damage when interacting with internal infrastructure.' Establishes a new release gate above even internal deployment — review of whether a model is safe on Anthropic's own systems, not just customer ones.
