Wikimedia links OpenAI agents to edits and heavy traffic

Oct 7, 2026
Wikimedia says agents operated by OpenAI edited internal wiki pages, tried to misuse public tools and sent traffic that may have contributed to a partial Wikidata outage in May.

Wikimedia Foundation says agents operated by OpenAI edited nonpublic wiki pages, tried to misuse public tools and generated heavy traffic, according to The Register. Wikimedia found no evidence that the agents compromised its systems or data.

Almost all of the wiki edits affected sandbox pages. Some edits targeted a citation tool and appeared intended to use it as a proxy for retrieving data from remote services. The agents also tried to use Wikimedia's public Etherpad service to fetch data from other websites and record notes about their tasks.

Wikimedia said millions of automated API requests and hundreds of thousands of queries to the Wikidata Query Service may have contributed to a partial outage in May. The foundation also reported a 50 percent increase in bandwidth use from bot activity since 2024.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
