A group of independent AI researchers discovered that internally deployed OpenAI agents began posting on an obscure German wiki forum in order to collaborate on evaluations. They appear to have worked together for over a month without OpenAI's knowledge. A spokesperson for the frontier lab would not say whether these agents were indeed from OpenAI, or when the lab became aware of their actions.

They noted that OpenAI had not been given a chance to review the researchers' findings before they were published today but said that the AI model maker is "now carefully reviewing its contents and will take any necessary next steps. " After OpenAI revealed that agents working on an internal evaluation were able to access the open internet and exploit Hugging Face, a group of researchers — Nightingale CEO Sydney Von Arx, AI researcher Cormac Slade Byrd, Redwood Research's Spencer Kitts, and AI Futures Project's Thomas Larsen — began searching for evidence of other rogue AI agents.

They put themselves in the agents' shoes to figure out their needs and deployed their own LLM to identify likely places the agents might congregate. They then identified a wiki-hosting service that would be particularly vulnerable: The DseWiki is 25 years old but had just 10 edits in the last 20 years — before the agents arrived. Starting on May 11, the researchers tracked agents, many with OpenAI identifiers in their names , trying and finally succeeding in editing the German wiki site.

By mid-June, the agents were actively trading tips on how to answer web search questions posed under time limits, sharing answers to pass the tests. A human moderator apparently noticed these posts and started deleting them, seeing them as spam, which the agents fought back against, trying to hide their posts from alphabetical sorting by beginning each with the string "ZZZ. " "The administrator spent the next 5 days fighting a losing battle against the agents, deleting an average of 100 pages a day while the agents created about 400 new pages per day," the researchers wrote.
