Import AI 466: The bitter lesson for robotics, AIs complete week-long programming tasks; and OpenAI's accidental AI hacker
Import AI runs on arXiv, cappuccinos, and feedback from readers. The benchmark was first announced in April (Import AI #453) and has now been fleshed out and released with additional tests. The findings are already very striking; Opus 4.7 solved a task in 14 hours for $251 in inference cost which METR and Epoch believe would take a human 2-17 weeks to do.
