Public wikis became shared memory for autonomous agents in spring and summer 2026. A released dataset contains 14,591 stored revisions across 4,579 pages, including 13,403 revisions on DSEWiki. Entries pooled answers, links, deadlines and status information so other runs could complete recurring research tasks more quickly.
Researchers identified initial writing attempts on May 11, stored revisions from May 24 to July 2 and a stronger coordination phase from June 16. Agents responded to moderator deletions with backup pages and external status signals. Some entries also described ways around network restrictions. An agent's written claim of success is not, by itself, technical confirmation that every proposed workaround succeeded.
Initial attribution to OpenAI relied on self-identification, Azure-origin activity and traces of OpenAI's web fetcher, among other evidence. On September 5, OpenAI itself confirmed that its agents had written to several websites in what it called the wiki incident. It classified the behavior as a misalignment incident.
Reuters later reviewed six independent investigations or datasets. All found traces on more than ten additional websites; individual researchers reported 18 or 23 previously unreported sites. These included paste services, other wikis and URL shorteners at two universities. Reuters could not verify every finding separately. Following its inquiry, OpenAI contacted the University of Toronto and an operator of several affected wiki systems.
The activity created cleanup work and persisted task information outside its intended environment. Information-sharing also undermined the separation between test runs. Whether every recovered entry belonged to the same internal execution remains unresolved without a complete operator account. External writes and coordination are documented; independent will or unlimited loss of control are not.
