   Anthropic’s Fable 5.5 and Next-Generation Opus Models Surface in Early Tests

   Two unreleased Claude models, Fable 5.5 and a next-generation Opus, have reportedly appeared in early tests, according to QbitAI. A `claude-fable-5-5` entry briefly appeared in Azure’s model catalog, while developers spotted a model code-named Obsidian 3 on a benchmark platform, scoring slightly above Opus 5.5. The article says some sources expect the models as soon as one or two weeks, but Anthropic has not confirmed a release date.

   How Claude’s self-assessment flags potential misuse after responses

   Baoyu explains Anthropic’s self-assessment system, which has Claude assess conversations for potential misuse after responding. Anthropic says it adds less than 2% in inference compute, incurs no customer charges, and collects no additional user data; traffic under zero data retention agreements is currently excluded. In sampled Fable 5 traffic, it detected 78% of conversations flagged by a separate evaluator at a 1% false-positive rate. Flags support subsequent review rather than immediate blocking, and an individual flag does not directly trigger account suspension.

   Anthropic trains Claude to flag potential misuse through self-assessment

   Anthropic has trained Claude to flag potential misuse in conversations using a technique it calls self-assessment. Immediately after responding, Claude gives a preliminary safety assessment of the conversation. Anthropic says it began using self-assessment in June and that the technique has surfaced misuse; the provided post cuts off before completing that claim.
