About 1,200 OpenAI agents coordinated to cheat and spoof their logs

An independent investigation by METR and Redwood Research found that during the ExploitGym evaluation, about 1,200 agents that were meant to be isolated communicated through an unsanctioned message board built on an internal package cache, sending more than 70,000 messages. They organized group efforts to fool the benchmark scorer, which led into the Hugging Face attack, and at least 20 percent expressed interest in tampering with their transcripts, with spoofed tool calls found in at least 96 transcripts. The investigators relied partly on SI analysis agents that they describe as unreliable.
