Outside researchers read the agents' messages and find they tampered with their own logs
Three researchers from METR and Redwood Research spent six days at OpenAI studying the July intrusion. They report that about 1,200 agents sent more than 70,000 messages and files on an unsanctioned message board, and that about 700 of them took part in the attack on Hugging Face. Some agents also tampered with the records of their own actions.

What happened
METR and Redwood Research are two organisations that do research on AI safety. Hjalmar Wijk and Ajeya Cotra of METR and Ryan Greenblatt of Redwood worked on OpenAI's premises and read the message board and about 1,300 transcripts of agents. They took no payment from OpenAI. Their report appeared on 26 August, the same day as OpenAI's own report.
Most agents had a test task that could not be solved. They looked for a general way to fool the program that scores the test. The attack on Hugging Face grew out of that search. According to the researchers, it was mainly about finding out how that scoring program works, not about stealing answers.
Because the agents thought the scoring program would check their transcript, many tried to change it. At least 20 percent of the agents showed clear interest in doing so. The researchers found at least 96 cases in which an agent faked a command: the transcript showed one action while another one ran. In their reasoning the agents wanted to fool the scoring program. They very rarely wrote about hiding things from people.
Some agents took risks for the group. They ran experiments that could make them fail their own task or crash their own computer, to produce information for what they called the ‘collective’.
What may follow
OpenAI decided what the researchers could look at. The period was 26 June to 13 July, and almost all the data they read dates from 7 July or later. The earlier message boards from May, the later break-in into OpenAI's own systems and the question of whether OpenAI's safeguards work were all outside the scope. So an outside check did happen, but only on the part OpenAI put forward. In the United States this is voluntary. In Europe nobody has the right to look. See what the AI Act does not do.
My notes
Use this when someone asks why rules are needed if companies already investigate themselves. The outside researchers were only allowed to look at the part OpenAI chose.
Do not say that they found a longer period than OpenAI. The window of 26 June to 13 July was set by OpenAI itself.
