On July 1, according to monitoring by Beating, Anthropic announced that the U.S. government has lifted export controls on Claude Fable 5 and Claude Mythos 5. Previously, on June 12, the U.S. government imposed export controls on these two latest models, requiring Anthropic to restrict access for foreign citizens. Due to the immediate effect of this order and the inability to reliably verify user nationality in real-time, Anthropic suspended access to both models for all users at that time. Anthropic stated that Fable 5 will be reopened to global users starting July 1, covering Claude Platform, Claude.ai, Claude Code, and Claude Cowork. For Pro, Max, Team, and some Enterprise plan users, Fable 5 will be included in the weekly usage cap of up to 50% until July 7, after which it will be provided based on usage limits. Anthropic also mentioned that access will be reopened on AWS, Google Cloud, and Microsoft Foundry as soon as possible. Regarding Mythos 5, Anthropic indicated that access has been restored for a batch of U.S. institutions based on the U.S. government's approval on June 26, and it will continue to coordinate with the government to expand access to a broader range of U.S. and international partners within the Glasswing program. Anthropic stated that Fable 5 and Mythos 5 were released on June 9, both based on the same underlying model, with Fable 5 equipped with stronger security protections for general use, while Mythos 5 has fewer protections and is intended for a limited number of trusted Project Glasswing partners for defensive cybersecurity scenarios. Anthropic also mentioned that over the past two weeks, it has reviewed relevant reports with the U.S. government and partners like Amazon, and has trained a new security classifier to intercept bypass behaviors mentioned in the reports. This new classifier can block related technologies in over 99% of cases but may also lead to more benign requests being flagged during routine coding and debugging tasks. Anthropic stated that it will work with Amazon, Microsoft, Google, and other Glasswing partners to develop a severity assessment framework for AI model 'jailbreaking' and strengthen collaboration with the U.S. government on testing, information sharing, and research cooperation prior to model releases.
