forklog.media Anthropic Halts Access to Fable 5 and Mythos 5 Models

Anthropic has suspended access to its Fable 5 and Mythos 5 models, which were introduced on June 9, due to a directive from the US government under export control regulations. The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.The net effect of…— Anthropic (@AnthropicAI) June 13, 2026 The company stated that the directive formally prohibits access by any foreign nationals, including foreign Anthropic employees, leading to a complete service shutdown. Anthropic's statement was published on June 12. According to the company, the directive was received the same day at 5:21 PM Eastern Time. The letter lacked specifics on national security risks. Anthropic linked the authorities' decision to techniques bypassing Fable 5's safeguards. The company claims to have reviewed the demonstration and found only a small number of previously known minor vulnerabilities. According to them, such vulnerabilities are relatively simple, and other publicly available models can also identify them without bypassing safeguards. Before launching Fable 5, its security mechanisms were tested by the US government, the British AISI, several third-party organizations, and internal teams. Thousands of hours were spent on testing. Anthropic stated that a universal jailbreak for the model has not yet been found. The company reminded that Fable 5 has a 30-day data retention policy for clients to investigate and close bypasses. However, according to them, the government only provided verbal information about a possible narrow, non-universal jailbreak. The supposed technique, as described by Anthropic, involved asking the model to read specific code bases and fix software errors. Anthropic stated it reviewed the report believed to be the basis for the directive and concluded that the demonstrated capabilities are also available in other models, including OpenAI's GPT-5.5. The company emphasized that it will comply with the legal requirement but disagrees with the withdrawal of a commercial product due to a narrow potential bypass. In their view, such a standard for the entire industry would effectively halt the launch of new models. Access to other Anthropic products remains unchanged. The company apologized to customers and stated it is working to resolve what it called a "misunderstanding." Earlier in June, Anthropic CEO Dario Amodei urged the US to tighten its approach to AI regulation and move from a disclosure regime to mandatory safety checks for the most powerful AI models.
