Alex Albert Says Robotics Will Follow the Bitter Lesson

Alex Albert says robotics will follow the bitter lesson, linking to a post from Claude AI. The cited post says Fable 5.2 improved at controlling physical robots, including on tasks it had never explicitly been trained to do, and outperformed other models and most AI systems built to control robots on RoboDojo, a simulated two-arm robot benchmark.

Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, lowering API prices to $8 per million input tokens and $40 per million output tokens, from $10 and $50. Anthropic says both models improve coding, reasoning, and vision, and that Fable produces responses faster than version 5.1. Fable is available to paid users with safeguards for risky cybersecurity and biology tasks; Mythos is limited to organizations approved through Anthropic’s verification programs. The launch reports cite strong benchmark results, including Fable’s first-place score on Artificial Analysis’ Intelligence Index v5 at its highest compute tier. Those figures come from the named benchmark evaluations; Anthropic’s prerelease examples also include software migrations, electronic devices, and physics problems. TechCrunch reports that an optional faster serving mode costs twice as much, while the lower API prices apply to standard use.
