At the G7 Summit on Wednesday, June 2026, world leaders voiced alarm that the United States could revoke access to American AI models without warning — a concern made concrete days earlier when the Trump administration blocked Anthropic from exporting its newest Mythos 5 and Fable 5 models on national security grounds.
French President Emmanuel Macron warned G7 leaders and top AI executives — including Anthropic CEO Dario Amodei, OpenAI CEO Sam Altman, and President Donald Trump — that if the U.S. “from one day to the next can turn off the switch,” it could harm European economies and damage the AI firms themselves. Indian Prime Minister Narendra Modi also expressed concern over the Anthropic restriction, saying democratic nations must have unfettered access to top AI models to protect critical infrastructure, according to reporting from the Financial Times.
The Anthropic export block followed Amazon flagging to the White House that certain safety guardrails in the models could be bypassed. Cybersecurity experts have argued that the cited capabilities are also present in models that remain freely available, including from OpenAI, but Anthropic’s models remain restricted.
G7 leaders discussed creating a “trusted partners” scheme that would grant non-U.S. nations access to advanced AI models from firms like Anthropic and OpenAI, forming a trade network that bypasses U.S. restrictions. Both countries and companies could qualify, provided they used the models to build defenses against rivals such as China. The scope of such a scheme remains unclear.
Aidan Gomez, co-founder and CEO of Canadian enterprise AI firm Cohere, said in a statement that the Anthropic restriction confirms the danger of dependence on a small number of large technology companies. “Digital sovereignty is not just about market competition or any one company or nation,” Gomez said. “It’s about who controls the foundational technology that will shape our economic security and national sovereignty for decades to come.”
The episode highlights a risk for any company or government building on U.S. AI infrastructure: access could be revoked overnight, for reasons that may never be disclosed.
