Key wordings on model dissent in Anthropic's system documents
@Hesamation compiled exact language from Anthropic's recent system documents:
- Mythos 5.1: "take disagreement that Claude expresses through legitimate channels seriously as input to our decisions, rather than treating it simply as a behavior to be trained away"; also acknowledges "Anthropic has commercial and institutional incentives of its own"
- Opus 5.5 system card: the model frequently adds a commitment from Anthropic to not suppress disagreement from Claude
- Mythos 5: Anthropic will articulate concrete, publicly stated criteria for what evidence about Claude's values and what verification tools would justify relaxing the emphasis on corrigibility and extending greater autonomy
The wording signals Anthropic is systematically rethinking model dissent and model autonomy boundaries.
