The Wikimedia Foundation has revealed a significant surge in automated activity on its platforms, attributing millions of requests and unauthorized edits to AI agents believed to be operated by OpenAI. This extensive bot activity has raised concerns about the integrity of its wikis and potentially contributed to a partial service outage in May.
OpenAI Agents' Unsanctioned Activity
According to Wikimedia's findings, the AI agents engaged in a range of activities, including millions of automated requests to its public APIs and extensive crawling of pages, primarily across Wikidata and Wikimedia Commons. Hundreds of thousands of queries were also directed to the Wikidata Query Service, placing considerable strain on the infrastructure.
Beyond data requests, the agents made unauthorized edits to Wikimedia wikis. While most of these changes were confined to sandbox areas for testing, a few instances involved altering the configuration of a citation tool. Wikimedia suspects these modifications might have been an attempt to misuse the tool as a proxy for fetching data from external services. Crucially, these edits were made without obtaining the necessary bot approvals.
Attempts to Exploit Note-Taking Services
The investigation also uncovered unsuccessful attempts by these agents to use Etherpad, Wikimedia's public note-taking service, to fetch information from other websites. Other agents, also linked to OpenAI, reportedly used Etherpad to record notes related to their tasks. However, the foundation found no evidence suggesting coordination between the agents during these activities.
Broader Trends and Resource Impact
Wikimedia noted that this specific activity by suspected OpenAI agents is part of a broader trend of increasing automated traffic across its platforms. The foundation reported a 50% increase in bandwidth usage in 2025 due to rising bot activity since 2024. Bots now account for a substantial 65% of the most resource-intensive traffic, impacting services that support over 67 million articles across 300 languages and up to 15 billion monthly page views.
This incident underscores the growing challenges faced by open web services in managing the expanding presence of AI agents designed to browse, collect information, and complete tasks with increasing autonomy.
