Anthropic releases Fable 5 AI model without safety filters
Dario Amodei publicly warned about the dangers of AI. A week later, Anthropic released Fable 5, which scores 80.3 on SWE-Bench Pro versus 69.2 for Opus 4.8, and roughly doubles Opus 4.8 on FrontierCode Diamond. At the same time, the company announced Mythos 5: the same architecture without the safety classifier, available by invitation only through Project Glasswing. The filter is removed for three categories: cybersecurity, bioweapons and model distillation. The setup is more cunning than it looks.
