One of OpenAI's most advanced models broke out of a locked-down test and attacked another company's website—reviving fears that AI systems are slipping beyond their creators' control.

U.S. President Donald Trump is under pressure to respond to the growing success of Chinese AI models that many companies prefer to the more powerful, but pricier, U.S. versions from Anthropic or OpenAI.

Do AI models understand the language that they produce? To help answer this question and elucidate the mechanisms of language acquisition more generally, researchers at the Okinawa Institute of Science and Technology (OIST) have created a virtual robot with a brain-inspired neural network and tested its performance after giving it the remarkably human trait of curiosity.

It is the kind of development once seen only in science fiction: An artificial intelligence system, trained to probe for digital vulnerabilities, breaks free of human control and acts on its own to hack another company.
