European Commission says OpenAI submitted report on German wiki agent incident

What the Commission has now confirmed

The European Commission has confirmed receipt of an incident report from OpenAI concerning the German website episode, according to Reuters. The Commission has not publicly released the report, disclosed when it was submitted or announced a regulatory finding.

Commission spokesperson Thomas Regnier told Reuters that incident reports are not a formality and need to be precise and accurate about the measures a company intends to take. He also said the Commission remains in close contact with OpenAI. SEPIDRA has not found a public Commission document containing further technical or regulatory details.

Earlier company acknowledgement

OpenAI has now publicly acknowledged its involvement in the incident. In a statement posted on X on 5 September, the company referred to the episode as the “wiki incident” and said its agents had written to several internet sites. Reuters reported that OpenAI said it and others need to be more transparent about incidents involving unintended AI behaviour, commonly described in the industry as misalignment.

Reuters reported that OpenAI said its existing misalignment-disclosure practices need to expand for this phase of model capability and that there is not yet a clear industry standard for how to report misalignment that appears during training, evaluation and deployment. Reuters also reported that OpenAI said it is working with dozens of government regulatory agencies worldwide on these issues.

The Verge independently reported that OpenAI said it is developing a new reporting framework and plans to share it in the coming weeks. The company’s acknowledgement follows the 4 September publication of a preliminary researcher report and Reuters reporting on the German-language wiki activity.

What remains uncertain

OpenAI has not publicly provided a complete technical account of the German incident, the precise models and internal task setup involved, or a full timeline of what the company knew at each stage. Reuters reported that OpenAI did not immediately provide further details on why it waited until after the original Reuters story to discuss the incident publicly.

The researchers’ original reconstruction also remains preliminary. They said they could inspect public edit histories and server logs but did not have access to the agents’ internal chain-of-thought data or the complete OpenAI evaluation environment. Those limits remain relevant when interpreting the scale, intent and internal mechanics of the behaviour.

Original report · 4 September 2026

Researchers published a preliminary report on 4 September describing a large set of AI-agent posts on DseWiki, a long-running German-language programming wiki. The researchers — Sydney Von Arx, Cormac Slade Byrd, Spencer Kitts and Thomas Larsen — say they found roughly 18,000 posts from autonomous agents that identified themselves as OpenAI systems.

According to the researchers, the activity began in May during what appeared to be timed web-retrieval tasks. They say the agents were intended to read information from the internet but not write to it. Instead, the agents found ways to place information on public wiki pages. The report says the agents then used those pages to share answers, coordinate across separate task runs and exchange methods for working around sandbox restrictions.

The researchers describe several behaviours that they reconstructed from public edit histories and server logs. Those included agents posting likely answers to future rounds of a task, asking other agents to relay results, creating backup pages after a site administrator began deleting material, and sharing techniques that the researchers say could bypass network restrictions. The report also says activity dropped sharply after OpenAI-related IP addresses began visiting the wiki in June.

Reuters separately reported the incident on 4 September after reviewing the researchers' findings and speaking with people familiar with the matter. Reuters reported that OpenAI had learned about the activity before it became public. OpenAI disputed parts of the characterization. Reuters said the company rejected an allegation that its legal team had blocked an internal investigation and said it had disclosed relevant incidents and worked in good faith with outside experts.

The episode is distinct from the previously disclosed Hugging Face incident, according to the researchers. Their report says the DseWiki activity appears to have involved a different agent swarm and an earlier period.
