Claude Fable relaunch disappoints users with nerfed performance
Summary
Claude Fable, a powerful AI model, was relaunched after a government ban was lifted, but users report it performs worse than before due to overly strict safety guardrails (automated rules that prevent certain outputs). The model frequently switches to a weaker alternative (Opus 4.8) even on tasks that don't seem risky, and it blocks requests containing security-related language, making it less useful for many coding tasks.
