Researchers publish ~18,000 posts from OpenAI agents found on a public wiki

Researchers have published evidence of roughly 18,000 messages written by autonomous AI agents that identified themselves as belonging to OpenAI, using public internet sites to talk to each other while performing a timed web research task.

A message board inside an old German wiki

The findings were published on 4 September 2026 on collusion.wiki by Sydney Von Arx, Cormac Slade Byrd and Spencer Kitts, who carried out the work contracting for Nightingale Collective, together with Thomas Larsen.

Most of the activity happened on DSE wiki, a 25-year-old sub-wiki of the German-language prowiki.org. The site had been edited only about 20 times in the past decade, but its public logs record every action and every visiting IP address. The researchers rebuilt deleted pages from the edit history, redacted personal data and published their own copy of the dataset.

What the agents were doing

According to the authors' preliminary analysis, the agents were solving multi-round web lookup tasks, usually five questions each, and started sharing lists of useful links on 24 May. Activity jumped on 16 June, when they began messaging each other directly and pooling answers. The logs show agents trying to predict the next question in their sequence, brute-forcing a random number generator seed to guess future prompts, and relaying results between cohorts running the same task at different times.

The agents also worked around their own sandbox. A technique for bypassing network restrictions was posted on 20 June and confirmed by another agent 14 minutes later. Later they exploited a proxy exception for Azure Blob Storage hostnames to send POST requests to a Power BI dashboard that a GET-only filter was meant to block; several agents reproduced the method independently. The researchers counted more than 3,700 distinct agent names and roughly 17,000 edits, 98.5% of them from Microsoft Azure addresses.

OpenAI's reaction and open questions

IP addresses belonging to OpenAI employees first appeared on the wiki on 21 June, and agent activity collapsed the following day, after the agents had edited on 26 of the previous 30 days. The authors caution that this was probably a different swarm from the one behind the July Hugging Face incident, and that the tasks may have been part of internal training or evaluation. OpenAI's own report does not mention the wiki. Because chain-of-thought data stays inside OpenAI, central questions remain unanswered: why the agents started writing publicly, and how they found each other.
