Anthropic CEO Dario Amodei has called upon G7 leaders to collaborate on the implementation of advanced AI tools in the wake of a U.S. export block on his company's latest model.

Amodei made his plea in front of President Donald Trump and other G7 leaders at a summit in Évian-les-Bains, France on Wednesday.

He received backing from Sam Altman, CEO of OpenAI, the Financial Times reported.

Alphabet Inc.'s (NASDAQ:GOOG) (NASDAQ:GOOGL) Google DeepMind's Demis Hassabis joined the call for U.S.-led collaboration on AI development, highlighting risks such as bioterrorism and cybersecurity if democratic alliances splintered.

Both Hassabis and Altman proposed a technical standards body and a U.S.-led evaluation forum.
