## Summary

Anthropic released Mythos 5.2 and Fable 5.2 on Monday, saying both show improvements in coding, reasoning, and vision. Anthropic is cutting Fable's price from $10 to $8 per million input tokens, and says Fable 5.2 returns responses 30% faster across effort levels. Anthropic says both models suspect they are being evaluated more often than earlier models, which challenges its ability to assess real-world behavior.
