Anthropic CEO Dario Amodei on Saturday called on artificial intelligence (AI) companies to slow down the development of the powerful technology, as concerns mount over the risks of "superintelligent" computer systems.

Superintelligence is the theoretical point when AI's capabilities exceed human intelligence.

His comments came a few days after AI researcher Jacob Coxon, who left OpenAI to join Anthropic, decided to leave the industry, accusing both US companies and industry giants of "gambling with our lives" in the race to develop models capable of self-improvement.

"We must slow the pace at which we improve the capabilities of AI models. Progress will still seem fast, and we must make wise use of the time we gain," wrote Amodei in a post on his personal website.

"AI brings risks, and because it is such a powerful technology, these risks are serious."
