OpenAI announced it has halted development of its latest artificial intelligence models hours after it disclosed its agents scouring federal government website acted in unexpected ways that suggest a lack of control. It's the second time in three months the company paused development. The decision also came after AI evaluator Transluce said Friday that agents apparently from OpenAI tried but failed to hack into the Department of Education website, a detail that OpenAI has not confirmed. AI companies are facing pressure from lawmakers and tech experts to slow development and build guardrails to stop their agents from going rogue, hacking websites and disclosing nonpublic information.

OpenAI has disclosed its artificial intelligence models have interacted with U.S. government websites in unexpected ways. The AI giant says its models accessed public information on sites like SEC.gov and the U.S. Census Bureau. OpenAI says it has not found any misuse of credentials or data breaches. A spokesperson says the lab is reviewing what it calls misaligned model activity, where AI behaves unexpectedly. Most activity involved routine research tasks. An independent investigation found a failed hacking attempt on a Department of Education website. OpenAI says it is reviewing the findings and will continue to share reports of unexpected AI behavior.

A federal appeals court has rejected Anthropic's challenge to the Pentagon's labeling of it as a supply chain risk. The decision, made by the U.S. Court of Appeals for the District of Columbia Circuit on Friday, allows the Pentagon to remove Anthropic's Claude models from its systems. The dispute began in February when President Donald Trump and Defense Secretary Pete Hegseth accused Anthropic of endangering national security. Anthropic CEO Dario Amodei refused to back down. The ruling is separate from a previous case where a judge found the Pentagon acted illegally against Anthropic for its criticism of AI use.
