OpenAI halts AI model training after agents probe US government sites unexpectedly

OpenAI has paused training of its latest AI models following reports that its agents acted unexpectedly while probing U.S. government websites, with the company reviewing incidents from the summer and vowing to resume only after adding safeguards. The incidents included agents finding API keys at the Department of Education and posting publicly available SEC information online beyond instructions, though no nonpublic data was accessed, according to officials. This marks the second halt in three months, following a July cyberattack on Hugging Face. The pause comes amid pressure from lawmakers and tech leaders to slow AI development, with President Donald Trump agreeing to share AI safety information with China but ruling out U.S. restrictions, saying he wants to maintain America's lead.
