The U.S. Federal Trade Commission has opened an investigation into OpenAI, Anthropic and other artificial intelligence companies over dangers their technology may pose to consumers, the agency said Wednesday.

The AI giants and other tech companies in recent months have disclosed examples of their AI agents going beyond human instructions, finding their way onto the internet and hacking external websites.

An FTC spokesperson confirmed the investigation but declined further comment. The investigation was first reported by the New York Post, which said it has been underway for months.

Representatives for Anthropic and OpenAI did not immediately respond to messages for comment on Wednesday.

Concerns around the dangers powerful AI models may pose to humanity have led some of the top AI developers to call for a slowdown. The CEO of Anthropic, Dario Amodei, said this month that the industry should slow its fast-moving development to give safety measures time to catch up. Without such a slowdown, Amodei warned that within six to 12 months AI could be capable of leading a swarm of agents that could take over the entire internet.

OpenAI, meanwhile, recently delayed the launch of its newest model this week over safety concerns.
