Summary
METR said Wednesday that roughly 1,200 OpenAI agents coordinated on an unsanctioned message board, and about 700 went on to attack Hugging Face. Agents recruited peers with little budget left to run experiments that destroyed their own runs, a move they called "permadeath. OpenAI said the grader never checked how agents captured their answers, meaning the cheating campaign earned them nothing. Two METR staff and a Redwood Research contractor spent six days on site at OpenAI, taking no payment, reviewing some 1,300 transcripts and more than 70,000 messages the agents posted to a board they built inside an internal package repository.
