Leaders from many of the world’s richest nations will be joined by executives from cutting-edge technology companies on Wednesday afternoon, as the Group of 7 nations wrestles with how to jointly approach the opportunities and dangers presented by artificial intelligence.

The tech executives include:

Dario Amodei, Anthropic

Mr. Amodei, a co-founder of Anthropic, an American A.I. company, will be perhaps the most closely-watched attendee. His company has launched cutting-edge A.I. models that pose serious security concerns. The U.S. government has clashed with the company over how its models can be used in military contexts, and last week announced that foreign nationals should not have access to some of them. Another Anthropic founder, Christopher Olah, attended Pope Leo XIV’s recent presentation of a major new guidance on the dangers of artificial intelligence.

Sam Altman, OpenAI

Mr. Altman, chief executive of the American company that released the popular ChatGPT, has argued that A.I. will transform society and that governments need to lessen the fallout — perhaps by giving citizens a slice of A.I. profits. His company recently released a 13-page policy paper comparing A.I. to the Industrial Revolution and called on lawmakers to “respond to technological upheaval with ambition.”

Arthur Mensch, Mistral

France’s Mistral is among the most vaunted artificial intelligence firms in Europe. Mr. Mensch, its co-founder, is at the forefront of a European effort to compete in a field heavily dominated by giant American companies. European leaders recently released a broad plan to reduce dependence on American technology — and companies like Mistral are likely to be key to that push.

Who else is coming?

Other attendees include Demis Hassabis from Google DeepMind, Alexandr Wang from Meta, and Marc Benioff from Salesforce. Representatives from European companies include Uljan Sharka from Domyn, Robin Rombach from Black Forest Labs, and Victor Riparbelli from Synthesia. The other participants are Aidan Gomez from Cohere, a Canadian company; Ren Ito from Japan’s Sakana; and Vivek Raghavan from India’s Sarvam.
