Anthropic Launches First Mythos-Class AI Model Claude Fable 5
Anthropic has released Claude Fable 5, its most powerful widely available AI model and the first from the previously withheld Mythos class. The company claims new safeguards make the release safe by blocking responses in high-risk areas like cybersecurity and biology, falling back to the Claude Opus 4.8 model. Pricing is double that of Opus 4.8, at $10 per million input tokens and $50 per million output tokens.
