Anthropic says Trump admin. lifted restrictions on powerful Claude AI models

Artificial intelligence firm Anthropic announced Tuesday that the federal government has lifted a set of restrictions on its powerful Claude Fable 5 and Mythos 5 AI models. This resolution follows a weekslong dispute between the Trump administration and the AI company, allowing Anthropic to begin restoring access to its models.

“

we will begin restoring access Wednesday.

The conflict began earlier this month when the U.S. government imposed export controls, prompting Anthropic to block foreign nationals' access to Fable 5. The company stated these controls were based on concerns over potential "jailbreaks", techniques to bypass the AI's safety guardrails. Anthropic argued that the discovered vulnerabilities were minor and replicable across various AI models, questioning the necessity of recalling a widely deployed commercial model.

Commerce Secretary Howard Lutnick confirmed his team's engagement, stating they "worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America's leadership in AI." The interruption affected both Fable 5, released to the public with safeguards, and Mythos 5, a version with fewer guardrails intended for select companies.

in recent weeks, his team has "worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America's leadership in AI."

Last week, reports indicated a partial easing of controls, with the Commerce Department allowing certain entities to use Mythos 5 again. The full lifting of restrictions signifies a resolution to the standoff, occurring as the Trump administration grapples with the potential risks and benefits of advanced AI technologies. President Trump had previously signed an executive order for a voluntary review process for advanced AI models, expressing a desire not to impede U.S. leadership in the field.

We disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people.
