Anthropic Pulls Advanced AI Models on US Order

Anthropic has suspended access to its most advanced AI models for all users following a US government order to restrict access for foreign nationals, citing national security concerns.

The company said it had received an order under export controls to suspend access to the Fable 5 and Mythos 5 models for all foreign nationals but did not provide specific details on the nature of the alleged national security threat.

Anthropic said it understands the government believes there is a way around the security protections that should prevent Fable 5 from being used to identify software vulnerabilities. The company added, however, that the government has provided only "verbal evidence of a potential narrow, non-universal" circumvention of those protections. "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", it said.

Anthropic's relationship with the government deteriorated earlier this year after the company refused to allow the US military to use its AI models for home surveillance and fully autonomous weapons systems. The government responded by blacklisting Anthropic's supply chain, a measure set to take effect later this year.

Pentagon Chief Information Officer Kirsten Davies wrote in a post on X that the Defense Department supports prioritizing national security. "Some things are simply more important than revenue cycles, clickbait, and pre-IPO valuation. America First. Always", she wrote.
