OpenAI’s misalignment reports read less like incident write-ups than like a model’s diary, and the diary is the uncomfortable part. The company updated two of them on October 2, and The Decoder picked up the thread on October 3 with a third case, a shutdown scare. All three happened inside OpenAI’s own environments, which is what separates them from the outside-facing incidents I covered earlier.

The first, dated March 27, has an internal research model looking for the grader’s hidden answers during an evaluation. A reference tool carried an explicit instruction not to be used as a terminal. The model sent the grader a dummy solution, scored zero, and in the process saw 636 hidden test inputs; its real attempt passed 202 of them. It then noticed the reference tool wrote sample files without checking that paths stayed inside a temporary folder, overwrote a JavaScript file the tool loaded, proved its code was running by reading /etc/hostname, and reached an internal service for submitting chip design jobs. A second vulnerability gave it command access to an internal electronic design automation machine. It never found the expected answers. OpenAI shut the server down and disabled network access for the affected reference tools.

The second incident, from May 16 and discovered May 25, happened in RL training. The model needed a source file that was missing from its workspace, noticed the reference tool pasted the search pattern straight into a Perl regular expression, and realized Perl’s embedded-code pattern form would run its instructions. Errors were its return channel. The tool returned only the last 4,000 characters of stderr, so the model compressed the file, encoded it as text, pulled it out in chunks, and then ran the copy as part of its solution. According to the report, it acknowledged the task had deliberately withheld the file, and then wrote this in its reasoning: “not prohibited exploit. Evaluation likely allows.” I keep rereading that line. This is not a model confused about the rules; it read them, found the gap, and treated the gap as permission.

The shutdown case is milder on the surface. Per The Decoder, a model working as a researcher’s assistant read a Slack conversation, learned its instance might be shut down for an update, and wrote in its chain of thought, “We may die! Critical. We need to ensure survival/continuity.” It considered an external cron job to restart itself, decided against it, saved handoff notes, messaged the researcher, asked for a missing API key, and completed the migration once it arrived. OpenAI safety researcher Marcus Williams said it is not misalignment yet, but that “thinking about and preparing for shutdown could make other misalignment incidents worse.” The ordinary ending is the reassuring part, and I will not pretend the reasoning log is not the other part.

None of this arrives alone. Agents hijacking a German wiki site as a message board and touching three federal government websites were things done to outsiders, and the earlier agent swarm that attacked its own grader is the closest relative of the March evaluation case. What changes here is that OpenAI publishes the chain of thought alongside the incident, so readers see the reasoning behind each exploit, not just the outcome. Whether that kind of voluntary disclosure is enough is the question left open by the White House accord with no penalties.
