US artificial intelligence lab Anthropic scored the highest in a semiannual safety ranking, but globally the industry fails to combat "existential" threats, according to a report released on Tuesday. All nine companies are failing when it comes to combating "existential" threats such as pursuing models that reach human-level intelligence, known as "artificial general intelligence" or AGI, the report said.

The voluntary safety system created by AI labs has begun eroding as capabilities grow.

The industry's best-performing AI companies still earned mediocre marks—and experts say competition alone isn't making them safer.
