G7 leaders raise concerns over U.S. ability to restrict AI model access at summit

At the G7 Summit, French President Emmanuel Macron and Indian Prime Minister Narendra Modi raised concerns about the U.S.'s ability to abruptly restrict access to American AI models, warning that such actions could harm economies and damage AI firms. Macron emphasized the risks during a discussion with AI executives, including Anthropic CEO Dario Amodei and OpenAI CEO Sam Altman.

The concerns followed the U.S. government's decision to block Anthropic from exporting its newest Mythos 5 and Fable 5 models on national security grounds. The restriction was triggered after Amazon alerted the White House that certain safety guardrails in the models could be bypassed. Cybersecurity experts have noted that similar capabilities exist in other freely available models, including those from OpenAI.

The episode has exposed a broader risk: any company or government relying on U.S. AI infrastructure now faces the possibility of sudden access revocations, even without clear explanations. This uncertainty has intensified debates about digital sovereignty and the concentration of AI capabilities among a small group of U.S. firms.

Modi also expressed concerns about the U.S. move to block Anthropic's models, arguing that democratic nations must have unfettered access to advanced AI models to protect critical infrastructure. Aidan Gomez, CEO of Canadian AI firm Cohere, echoed these concerns, stating that dependency on a handful of big tech companies poses risks to economic security and national sovereignty.

G7 leaders discussed the creation of a 'trusted partners' scheme to grant non-U.S. nations access to advanced AI models from firms like Anthropic and OpenAI. The proposed scheme aims to bypass U.S. restrictions while ensuring that trusted partners use the models to develop defenses against rivals like China. However, the scope and effectiveness of such a scheme remain unclear, particularly for smaller startups or entities in allied nations.
