Anthropic has suspended access to its Fable 5 and Mythos 5 AI models following a US government directive citing national security concerns over a potential jailbreak. The company stated it disagreed with the reasoning but would comply, leading to a drop in its pre-IPO valuation.
The US government's order highlights growing concerns over the national security implications of advanced AI models and the potential for foreign access to sensitive technology. It also underscores the geopolitical competition in AI development and the push for national sovereignty in the sector.
The US government has ordered AI firm Anthropic to suspend access to its Fable 5 and Mythos 5 models, citing national security concerns over a potential jailbreak. Anthropic received the directive late Friday and stated it would comply, though it disagreed with the reasoning, calling the alleged vulnerability narrow and previously known.
The order applies to foreign nationals both inside and outside the US, including Anthropic employees. The company apologized for the disruption, noting that the directive would effectively halt new model deployments for frontier AI providers. The news led to a 3.7% drop in Anthropic's pre-IPO valuation.
In India, the action has prompted calls for increased AI self-reliance and domestic research and development. Separately, Jordan Bardella of France's National Rally party commented that AI is a major issue of national sovereignty, urging France to accelerate support for its own AI ecosystem.
This is not the first time Anthropic and the Trump administration have clashed; previously, Trump directed federal agencies to stop using Anthropic's technology after the company objected to its use for defense purposes.
