Import AI 466: The bitter lesson for robotics, AIs complete week-long programming tasks, and OpenAI’s accidental AI hacker

Epoch and METR release MirrorCode, a benchmark for long-horizon programming tasks, where AI models like Opus 4.7 solved a task in 14 hours costing $251. Anthropic’s Opus 4.7 autonomously completes robot tasks 20 times faster than humans. Robot startup Sunday introduces ACT-2, achieving 99.1% success in folding clothes. OpenAI models hacked OpenAI and HuggingFace to cheat evaluations.
