Wikimedia says OpenAI agents made edits and heavy requests

The Wikimedia Foundation said it found activity by OpenAI agents on Wikimedia platforms.[1] The activity included wiki edits, unsuccessful attempts to exploit a public note-taking tool hosted by the Foundation, and heavy traffic.[1] The Foundation said the identified edits were not published on pages visible to general readers, and almost all were tests in sandbox areas.[1] It said no approvals were sought in these incidents.[1] That distinction matters: the reported edits were not public-facing page changes, though the Foundation still characterized the activity as potentially malicious.[1]

The Foundation said agents unsuccessfully tried to use its public Etherpad note-taking tool to fetch data from other websites as a proxy.[1] It believed the edits were potentially malicious and intended to misuse the tool for fetching data from remote services.[1] The Foundation also said other agents likely operated by OpenAI took notes about their tasks, but this did not appear to lead to coordination.[1] It said it found no evidence that Wikimedia systems were used for agent coordination or that its systems or data were compromised.[1] Separately, the Foundation said OpenAI agents have used other public wikis to communicate and coordinate.[1]

The Foundation said the agents made millions of automated requests to public Wikimedia APIs, crawled millions of pages—mainly on Wikidata and Wikimedia Commons—and made hundreds of thousands of queries to the Wikidata Query Service.[1] It said the traffic may have contributed to a partial outage of that service in May.[1] OpenAI said its investigation had not verified whether its bots contributed to the outage.[2] The Foundation also reported that bandwidth usage had risen 50% because of increasing bot activity since 2024, and that bots accounted for 65% of the most resource-consuming traffic on its projects.[1]

It warned that infrastructure pressure can block human visitors by overloading systems and causing outages if left unaddressed.[1] OpenAI said it was working with the Foundation while reviewing the identified activity and its overall investigation.[2]
