Claude Fable relaunch disappoints users with nerfed performance

The relaunch of Claude Fable, Anthropic's powerful AI model, has disappointed users due to degraded performance and increased restrictions. Despite being available to all users, the model is heavily capped and frequently falls back to the less capable Opus 4.8 due to strict safety guardrails. Users report that prompts involving security-related terms or systems programming trigger fallbacks, impacting usability. Anthropic attributes this behavior to an expanded safety margin rather than intentional model degradation.
