The US government issued an export control directive on June 12, 2026 ordering Anthropic to shut off access to its two most powerful AI models – Fable 5 and Mythos 5 – for every user worldwide, including Filipino subscribers and developers who rely on the Claude API.
The order reached Anthropic at 5:21 PM Eastern Time. It targets any foreign national, whether inside or outside the United States, and because that scope effectively makes compliance impossible without cutting off everyone, Anthropic disabled both models for its entire customer base. All other Claude models, including Opus, Sonnet, and Haiku, remain available.
For Filipino users and Philippine-based businesses using Claude’s API or claude.ai, access to Fable 5 and Mythos 5 is suspended until Anthropic resolves this with the US government. Developers building on the Claude platform who upgraded specifically for Fable’s capabilities are affected. Anthropic says the outage is temporary and that it is working to restore access.
The government’s directive cites national security concerns and points to what it describes as a method of bypassing (or “jailbreaking”) Fable 5. Anthropic reviewed what it believes is the basis of the directive and disputes the severity of the finding. The company says the potential jailbreak amounts to asking the model to read a specific codebase and find software flaws – a technique it says produces results already available from other publicly deployed models, including OpenAI’s GPT-5.5.
Anthropic’s statement described the finding as a “narrow, non-universal jailbreak,” meaning it can elicit some specific information under specific conditions rather than broadly unlock the model’s capabilities. The company said it has found no evidence of a universal jailbreak – one that could widely bypass Fable’s safeguards – and noted that no testers across thousands of hours of pre-launch red-teaming were able to produce one.
“We are complying with the government’s legal directive and are removing access to Fable 5 and Mythos 5 for all users,” Anthropic said in its statement. “However, 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. If this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers.”
Anthropic said it plans to share more technical details about the jailbreak in question within the next 24 hours. The company said it is working to restore Fable 5 and Mythos 5 access as quickly as possible and that it believes the shutdown is the result of a misunderstanding.
