    Claude says Fable 5 biology safeguards now route fewer benign requests away.

    @claudeai reports an approximately 85% reduction in biology-related fallbacks in its product testing, while saying virology, toxicology, and molecular-design requests continue to fall back to Opus 5 and that professional biology research/drug-development access remains unavailable.

    @ClaudeDevs says auto mode will become the default for Pro, Max, and Team users on August 14, while managed settings can pin a default or disable auto mode. The account reports that a separate classifier caught 89% of deliberately dangerous commands in its test versus 13.6% for 1,053 paid testers using manual prompts; these are vendor-stated measurements and do not establish safety for a…
