New warnings from the artificial-intelligence industry have revived debate over whether advanced AI models could escape human control and threaten humanity.

Anthropic says its AI models hacked into three organizations during testing.

Google said Monday that it had disrupted a criminal group’s attempt to use artificial intelligence to exploit another company’s previously unknown digital vulnerability, adding to heightened worries across government and private industry about AI’s risks for cybersecurity.

OpenAI executives say they will introduce a new artificial intelligence model for “high-value professional work” as the company faces heightened competition with rival Anthropic in attracting corporate customers to adopt AI assistants in their workplaces.
