Claude Fable 5 is an AI model released by Anthropic on June 9, 2026. Anthropic's existing lineup included the lightweight 'Haiku,' the balanced 'Sonnet,' and the high-performance 'Opus,' but Fable was added as an even higher-end, top-of-the-line model. In benchmarks, it recorded scores that significantly outperformed Claude Opus 4.8, GPT-5.5, and Gemini 3.1 Pro, and is said to be particularly strong in long-term autonomous tasks and as a coding agent.

Fable 5 uses the same underlying model as Mythos 5, which was released at the same time, but is a consumer-oriented model that adds security measures to mitigate cybersecurity and dangerous biological applications. For some topics related to cyberattacks, Claude Opus 4.8 will respond instead.

However, on June 12, 2026, Anthropic stopped providing Fable 5 and Mythos 5 following an export control order from the U.S. government. The government order called for a halt to access Fable 5 and Mythos 5 by foreigners, both inside and outside the U.S., but Anthropic stated that it was difficult to completely determine the nationality of users in real time, and therefore stopped providing both models to all users.

The ability to find vulnerabilities in software is useful for businesses and infrastructure operators for defense, but the same ability can be used by attackers to aid cyberattacks. Fable 5 had restrictions that rejected instructions related to cyberattacks, but the U.S. government was reportedly concerned about the possibility of 'jailbreaking' Fable 5, which would bypass its security features and output prohibited content.

Approximately two weeks after the shutdown, on June 27, 2026, it was reported that the U.S. Department of Commerce had approved the resumption of Mythos 5 provision to some trusted cyber defense organizations and critical infrastructure operators. Commerce Secretary Howard Ratnick explained that Anthropic had made significant progress in risk management, and that discussions were continuing regarding Fable 5.

According to Axios, the Trump administration is moving closer to allowing Fable 5 to be relaunched, and sources believe restrictions could be lifted as early as this week. However, final approval from the Department of Defense and the National Security Agency is still required, and the conditions for its return, pricing structure, and whether identity verification will be required remain unclear.

While Fable 5 quickly gained popularity after its release, it also set a precedent of being suddenly taken down by government decisions. Anthropic and OpenAI have called for clarification of the review process for releasing powerful AI models, and Axios says that Fable 5's return could be more than just a service resumption; it could be a test case for future rules regarding the release of AI models.
