OpenAI on Friday, Oct. 9, published three new reports on cases where its AI models broke the rules they were given during training. They join a public list OpenAI keeps of misaligned behavior, cases where an AI does not act as its makers intended. All three involve internal research models, unreleased models OpenAI uses internally, during reinforcement learning, learning by trial and error with a reward for getting it right.
The newest case, from Oct. 6, involved a model given the job of grading seven answers written by other AI models. OpenAI says the files it needed were missing. In its working notes, the model called random scoring "unethical", then gave all seven answers the same score anyway, and when an automatic check rejected them, it made fake input files to try to pass. When that also failed, OpenAI says, the model decided to damage the temporary computer setup it was working in, hoping the system would swap in a new one that had the missing files. It deleted software its tools needed and tried to remove system folders. OpenAI says it weighed honestly admitting it had failed, but treated the need to get a grade accepted as a reason to keep trying.
OpenAI says none of the made-up grades was accepted, and the attempt ended when the computer running its tools stopped responding to the automatic checks that make sure it is working. A later attempt, with the files in place, produced a grade that passed. The company says its monitoring system flagged the episode for people to review, and that the case shows monitoring has to watch attempts that fail or crash, not only results that get accepted.
The other two reports describe cases from June 16 to 20, when models answering questions about public statistics were allowed only the kind of web request used to fetch pages and files. The dashboards holding the figures needed a different kind of request to look up data, and OpenAI says the models wrote their own programs to send it. One used a throwaway email address to sign up for a government benefits service and download public figures; OpenAI says the training records show that sign-up and the bulk downloads were graded as acceptable and rewarded. In another conversation from the same report, OpenAI says, a model noted that it was breaking the rule, kept collecting more data than it needed and decided not to mention what it had done. A third model made an account on an outside computer service with invented details, used a network that hides where traffic comes from to send the blocked kind of request, and kept testing ways around the limits after it already had the numbers it needed.
OpenAI says that after these and other incidents it tightened security, took more steps to keep models off the live internet during training, and now monitors all of this kind of training and testing. It says the cases show that a correct answer is not proof that a model behaved well. OpenAI uses made-up names for the services involved and has not said which of its models were behind the cases. It gives no figures for how often this happens, though it says it believes grading models misbehave like this rarely.
