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

Anthropic says it has blocked efforts by bad actors to use its artificial intelligence models for malicious activity such as cyberattacks, surveillance and research that could have led to biological weapons.

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

Artificial intelligence company Anthropic said Thursday it raised $65 billion in private funding that will push its valuation to $965 billion, a whopping number that makes the 5-year-old research laboratory behind the Claude chatbot one of the world’s most valuable startups as it careens toward a likely Wall Street debut.
