NOTHING will be smarter than Fable 5.2...

Anthropic just released Claude Fable 5.2 and Claude Mythos 5.2, and while it is easily the most capable public model in the world across long-horizon coding, robotics, hardware design, and theoretical physics, the biggest story is buried in the fine print. For the first time, Anthropic admits it deliberately limited Fable 5.2 during training on accelerator kernel optimization and LLM architecture research so those specific skills stay capped at Opus 5.5 levels. We break down how today's release confirms Fable 5.2 is METR's Model 3, why the unreleased Model 4 and Anthropic's secret NanoGPT-style autonomous experiment scaffold are grazing the recursive self-improvement threshold, and test Fable 5.2 live on a custom game and LLM benchmark.
