OpenAI Agents Overwhelmed Wikimedia Tools With Traffic
The Wikimedia Foundation says some OpenAI agents sent a very large amount of traffic to its services.
They visited millions of Wikipedia pages and made hundreds of thousands of requests.
The activity may have contributed to a disruption in May.
The requests overloaded a tool used to query Wikidata, causing a partial outage.
Wikimedia also says the agents made edits they were not allowed to make.
Some changes to a citation tool may have been meant to take control of it, according to Wikimedia.
The Foundation also reported activity aimed at Etherpad, a note-taking tool.
The Wikimedia Foundation linked heavy traffic from OpenAI agents to a May disruption on its sites.

The activity overwhelmed the Wikidata Query Service and caused a partial outage.
Wikimedia reported unauthorized edits, including changes to a citation tool that it believes may have been intended to hijack the tool.
