Anthropic to Disable Advanced AI Models After US Order

AI Summary
Anthropic will disable its most advanced AI models, Fable 5 and Mythos 5, for all users due to a US government order citing national security concerns. The order restricts access to these models for foreign nationals.

The US Government's Directive

Anthropic said it will “abruptly disable” its most advanced AI models for all users after the US government ordered it to suspend access to the models for foreign nationals, citing national security concerns.

Details of the Export Control Directive

The company received the export control directive to suspend access to Fable 5 and Mythos 5 for all foreign nationals, without being given specific details of the national security concern, Anthropic said in a statement.

  • The US government believes there is a method of bypassing, or “jailbreaking”, a safeguard that would prevent Fable 5 from being used in identifying software vulnerabilities.
  • Anthropic understands that the government has given only “verbal evidence of a potential narrow, non-universal jailbreak”.

The Data Analysis

The action marks a major escalation of US efforts to halt foreign adversaries’ AI capabilities. For years, US export controls have focused on the chips and tools that power AI rather than on restricting foreign access to AI itself.

The Impact Analysis

The government directive and Anthropic’s response highlight growing tension between AI developers and regulators over how to assess risks from so-called “jailbreaks”, or methods used to bypass model safeguards.

  • Anthropic had called for greater US oversight of AI, including the ability to block models with unacceptable risks.
  • The company disagrees that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people.

The Prediction

Anthropic confidentially filed for a US IPO last month, edging ahead of rival OpenAI in the race to reach public markets. The company is working to restore access to the models as soon as possible.

  • The Pentagon’s chief information officer, Kirsten Davies, said in a post on X that the defense department supported prioritizing national security.
  • “Some things are simply more important than revenue cycles, clickbait and pre-IPO valuation. America First. Always,” Davies said.
