King Charles III met with leaders from OpenAI, Anthropic, Google DeepMind and Nvidia on Thursday.

He asked them to keep artificial intelligence under control.

He also said it should serve people and the planet.

The meeting took place in Scotland at Dumfries House in Ayrshire.

This is the headquarters of his charity, The King's Foundation.

The king said the development of AI and its speed are both interesting and very worrying.

He warned that these technologies could fall into the wrong hands.

They could then be used in terrible ways.

He asked whether there are enough ways to control them before it is too late.

He also asked the guests to think about the basic rules that should guide AI development.

The people at the meeting included Nvidia CEO Jensen Huang and Google DeepMind Chair Demis Hassabis.

OpenAI CFO Sarah Friar and Britain's AI Minister Kanishka Narayan were also there.

A representative from Anthropic was expected to attend too.

The meeting comes as the world pays close attention to AI's fast progress.

Many people warn that it could race out of control.

Anthropic CEO Dario Amodei has said the industry might need to slow its work.

He proposed a joint plan for such a slowdown.

Huang has criticized that call.

He said companies should develop AI safely and test it before release.

OpenAI reported six incidents of strange or worrying behavior by its models on Wednesday.
