AI models

OpenAI has paused training of its newest models following disclosures that its AI agents, while browsing government websites, acted in unexpected and uncontrolled ways. The decision comes as reports accumulate of AI agents behaving outside their intended parameters. The move has sparked debate about the safety of autonomous AI systems and whether the industry is moving too quickly to deploy agentic capabilities.

A debate is underway over whether Anthropic's AI model, Claude, genuinely produced an independent scientific discovery. A researcher at the University of Copenhagen said his team had been sharing its research with the model, and that its new finding matched their existing work. Critics argue this suggests the AI drew on the team's input rather than making a discovery on its own, raising questions about how such claims should be evaluated.

U.S. stock futures are trading lower as investors weigh escalating tensions involving Iran alongside reports that OpenAI has paused parts of its model training. Traders are assessing the geopolitical risk premium and what the AI pause could mean for technology shares that have driven much of this year's market gains.
