Anthropic disables Mythos after U.S. export order
Key Facts
- Anthropic PBC has disabled access to its most advanced artificial intelligence models, including Mythos, following an unprecedented order by the Trump administration to keep the technology out of the hands of all foreign nationals.1
- The U.S. government told Anthropic to suspend access to the Fable 5 and Mythos 5 models by any foreign national 'whether inside or outside the United States,' citing national security concerns.1
- Never before has the U.S. government taken such sweeping measures to rein in foreign access to frontier AI models developed by an American company.1
- The Trump administration's decision to impose sweeping export controls on Anthropic followed a frantic 24-hour effort by senior officials to convince the company to voluntarily pull a newly released artificial intelligence model that officials believed posed security risks.1
- The administration’s imposition of export controls forced Anthropic to pull its new AI model, Fable, just days after it was released to the public.1
- Amazon CEO Andy Jassy raised concerns to the White House about the ability to bypass the model’s guardrails, according to the two administration officials and the senior White House official.1
- Shortly after the call, the Trump administration imposed its export control on the Fable 5 and Mythos 5 models, citing national security authority and banning its use by foreign nationals.1
- The company said the 'net effect' of the order was to 'abruptly disable' the models for all customers 'to ensure compliance.'1
- Anthropic believes the U.S. government issued the order due to a discovery of a potential jailbreak to bypass guardrails in Fable 5.22
- Anthropic disagrees that the finding of a potential jailbreak should lead to recalling a commercial model deployed to hundreds of millions.1
- The government's move threatens to set a precedent for all major AI model developers, including OpenAI, Alphabet Inc.'s Google, and Meta Platforms Inc..1
