TOKYO - The Japanese government is negotiating with U.S. artificial intelligence company Anthropic to obtain access to its latest AI model, government sources said Tuesday, amid growing concerns over cyberattacks using sophisticated AI tools.

The move comes as the Claude Mythos model is said to be so good at identifying vulnerabilities in web browsers and other software that it has sparked fears it could be exploited for attacks on a wide range of systems.
