During the final day of the G7 summit in France, world leaders discussed the future of AI with some of the biggest names in the industry, including Anthropic CEO Dario Amodei, and OpenAI chief Sam Altman. Dario reportedly urged world leaders to not splinter over advanced AI tools just days after the US banned his company’s Mythos 5 and Fable 5 models for all non-US citizens. Read Full Story As per a report from the Financial Times, the Anthropic chief told G7 leaders to “resist the temptation to splinter” over AI tools during a working lunch in vian-les-Bains, France, on Wednesday. He reportedly made these comments in front of US President Donald Trump. That is, Dario Amodei wants democratic countries to stick together when it comes to powerful AI tools which can do a lot of damage if they fall into the wrong hands.

Dario Amodei’s remarks come at a time when the US’ move to block access to Mythos and Fable has sparked debate over the future of AI geopolitically. Some believe that countries must reduce dependence on foreign AI tools as a country like the US can easily block access by flipping a switch. Sam Altman, Demis Hassabis support Dario Amodei’s comments OpenAI CEO Sam Altman and Dario Amodei are not known to have the best of relations. During the India AI Impact Summit in February this year, the two infamously refused to hold hands together on stage. However, when it comes to the topic of countries working together in the AI space, it seems that Dario and Sam have similar views. As per the report, Sam Altman agreed with Dario Amodei, and claimed that all countries that were attending the summit, including India, should have access to that cyberdefence tools.

Google DeepMind chief Demis Hassabis also joined the discussion. The three AI leaders insisted that the US must lead a collaborative effort on the development of AI models, while also pointing out potential risks in terms of bioterrorism and cyber security if democratic alliances fractured in the AI race. What are world leaders saying? The report added that French President Emmanuel Macron was quick to point out that if the US “from one day to the next can turn off the switch”, it would hurt the multitrillion-dollar American companies leading the AI race. Macron also called for “stronger regulation of AI” and warned against “non-cooperation among democracies.” He added that what would be built in the coming months would be “a platform for discussion and co-operation among a number of democracies” to define common standards together. Prime Minister Narendra Modi also raised concern over the US decision, as per the report.
