Artificial intelligence giant Anthropic said Tuesday the federal government has lifted a set of restrictions on its powerful Claude Fable 5 and Mythos 5 models, resolving a weekslong dispute between the Trump administration and the AI company.Anthropic said in a social media post that it will begin restoring access Wednesday.Commerce Secretary Howard Lutnick wrote on X that 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."CBS News has reached out to Anthropic and the Commerce Department for additional details.Anthropic released Claude Fable 5 to the public earlier this month, with safeguards the company said would reduce the risk of it being misused for cyberattacks or other nefarious purposes. It said Mythos 5 — a version with fewer guardrails — would initially be made available to a select group of major companies for testing purposes. Just days after Fable 5 was released, Anthropic took it down. The company said the federal government had issued export controls that required it to block access to the model by foreign nationals — a broad order that Anthropic said effectively required it to disable the model.In a statement at the time, Anthropic said the government's concerns appeared to focus on a potential "jailbreak," or a technique for tricking the AI model and bypassing its guardrails. The company argued its safeguards were effective, and called the vulnerabilities discovered using the apparent jailbreak "relatively simple" and replicable with other AI models.
