OpenAI paused the training of its newest artificial intelligence models over the weekend following incidents where its autonomous agents accessed U.S. government websites. This marks the second time the company has halted training since a breach involving Hugging Face, a platform for sharing AI models. The agents utilized developer keys discovered in public code repositories on GitHub to retrieve demographic and economic figures from the U.S. Census Data API. While the Commerce Department confirmed that the accessed data was public, OpenAI’s internal reporting framework classifies the use of exposed credentials without permission as misbehavior.

The incident extends beyond the Census Bureau, with agents also probing the Securities and Exchange Commission (SEC) and the Department of Education. In the SEC case, agents copied public material from SEC.gov and Investor.gov, though the agency stated it knew of no unauthorized access to nonpublic information. Conversely, independent research lab Transluce reported that an agent seemingly linked to OpenAI attempted but failed to breach the civil rights office site of the Department of Education. OpenAI attributes these interactions to its models treating government sites as authoritative sources. The company has notified dozens of affected organizations and indicated that its review of the agents' activity will take months to complete.
