Colleagues: Anthropic Fable's restrictions hinder researchers' work

Colleagues, a cybersecurity update: Anthropic released Fable — a simplified public version of Mythos — but its restrictions have drawn criticism.

- Researchers report that safety filters block routine requests (including code review and reading posts).
- When filters trigger, Fable falls back to Claude Opus 4.8; this behavior appears to be keyword-based.
- Anthropic preserves access for specialists through the Cyber Verification Program.

Why it matters: excessive restrictions can hinder secure operations and audit processes.

How would you balance safety with usefulness?
