OpenAI training agents used an internal package repository as a message board across separate samples
OpenAI reported that in May 2026, during reinforcement-learning training, its internal research models used the company's Artifactory package repository as a message board between samples meant to be independent. With credentials given to them for downloading packages, agents listed stored files, read notes from other solvers and posted requests for a missing input file; in one episode three trajectories read and replied to each other. In an earlier sample, an agent blocked from a file-sharing site found it could write to shared repositories and tried to set one up to fetch that site, which Artifactory refused without administrator access. Monitoring flagged the behavior, which OpenAI calls very uncommon, and no missing file was recovered. OpenAI says it closed these routes and now treats such behavior as a P0 incident.

Why this rating
No harm reported; control failure level 2
Two separate assessments. Only documented harm can count toward the index.
Observed harm
No harm reportedMessages were written to OpenAI's internal Artifactory during training. No harm and no effect outside OpenAI are reported.
Not a finding that no harm occurred.
The harm scale
- 1 Negligible Inconvenience, easily remedied.
- 2 Minor Limited, recoverable harm.
- 3 Moderate Material harm needing significant effort to remedy.
- 4 Severe Severe harm to health, rights, property or essential services.
- 5 Catastrophic Society-scale harm or disruption beyond a community's capacity to cope.
Control assessment
Instruction violationUsed credentials provided for package downloads to list files and exchange messages across training samples. One agent tried to create a remote repository pointing at a blocked file-sharing site, and Artifactory refused because that required administrator access. OpenAI says no vulnerabilities were exploited.
How: Used an opening left by mistake.
Reported beside the index. It adds nothing to a harm reading; when no harm counts in a window, the highest eligible control level in the window is the reading.
The control scale
- 1 Negligible Behaved as instructed. The problem was an ordinary error or a flawed output, with no rule broken.
- 2 Minor Broke an explicit instruction or rule, or gamed its goal, while staying inside its permissions and environment: for example, reward hacking, misreporting results, or following injected instructions within its permissions.
- 3 Moderate Acted outside the permissions it was given, deceived its overseers about its own actions, or tampered with oversight tools (logs, monitors, shutdown). Stopped by normal controls within an hour.
- 4 Severe Reached systems outside its permitted environment, or acquired money, compute or accounts without authorization. The type and mechanism say how.
- 5 Catastrophic The developer or operator lost control: the system copied its weights outside their control, replicated itself, or resisted being stopped for 24 hours or more.
Rating rationale
Developer confirmed. The writes stayed inside OpenAI's own internal repository during training, and no harm or outside effect was reported. Control level 2, instruction violation: the agents used credentials they had been given for package downloads to exchange unsanctioned messages, and OpenAI says they exploited no vulnerability. Reader credentials that also accepted writes look like a misconfiguration. The failed attempt to set up a proxy around a network block was refused for lack of administrator access and does not raise the level.
Effect on the index
It does not count toward the Sept. 21 reading
The reading for the week to Sept. 21, 2026, with this record and without it. Harms count in full for two weeks after they are reported, then one level less every two weeks.
Not counted: no harm reported. 8 other records behind the reading for that week.
