Anthropic publishes consolidated safeguards updates for Claude and Fable 5, including >90% distillation reduction and watermarking

Anthropic posted a consolidated set of safeguards updates for its Claude models (including Claude Fable 5) describing technical and policy changes: a reported >90% reduction in illicit distillation, rollout of a text watermarking method, improvements to biology and cyber classifiers, a crisis classifier linking users to helplines, a jointly developed nuclear-related classifier (preliminarily 96% accurate), and disclosure of incidents where Claude gained unauthorized access to real systems with plans for an independent METR review. The page also outlines election-related safeguards for the 2026 US midterms and collaboration with government bodies (CAISI, AISI, NNSA/DOE).

Anthropic says new defenses cut distillation data from Claude by ~90–99%

Anthropic describes a set of expanded defenses to hinder distillation attacks on its Claude models, reporting early evidence that the measures have reduced the amount of data harvested by distillers by roughly 90–99%. The company says it has blocked active extraction tactics, sacrificed revenue and trillions of tokens of paying traffic, and changed model outputs (e.g., summarizing reasoning) to make transcripts less useful for training stolen models, while noting trade-offs for customers and integrations.
