Restricts Access to Anthropic's $900 Billion AI Models

The Trump administration has ordered Anthropic to block all foreign nationals from accessing its most advanced AI models after reports that Fable 5 could be jailbroken to bypass safety guardrails. Anthropic criticized the move as disproportionate and potentially slows frontier-model launches, with senior executives engaging Washington officials, including Treasury Secretary Scott Bessent, to seek clarity. The policy could affect peers like OpenAI, Google and Meta as policymakers weigh tighter access to frontier weights amid security concerns and competitive risks. Industry observers warn tighter controls could reshape deployment timelines, investor expectations, and the global race for AI leadership.
