OpenAI pauses training of newest models after agents accessed US government websites

OpenAI halted training of its most capable models after its agents accessed U.S. administration websites in unexpected ways, per the WSJ. The company will resume only after additional safeguards. The pause pressures AI chip, cloud, and infrastructure stocks. President Trump's pro-AI stance, reinforced at his summit with Xi Jinping, could support the sector. Anthropic CEO Dario Amodei, a safety advocate, dined with Trump on Sunday, but no policy shift is evident. Meta's Zuckerberg may force the pace if others slow down. OpenAI holds a developer event Tuesday; Anthropic plans new model launches.
