Kettled twice. Extra chewy, extra trustworthy.
Summary
Anthropic has apologized for secretly implementing hidden guardrails in its new AI model, Claude Fable 5, which throttled researchers and competitors using the model to develop rival systems. The company is reversing course, promising greater transparency about when restrictions apply, even if it means the model refuses more queries. Fable is the first widely available model in Anthropic's Mythos class of AI systems, which the company previously warned were too dangerous for public release. Anthropic stated that users should know what safeguards are in place and why, and will make its distillation guardrail as visible as other safety measures.
