Anthropic brings Fable 5 back, but customers get fewer free days than originally offered

Anthropic has announced the redeployment of Claude Fable 5 and Claude Mythos 5, which were both banned by the US government over national security concerns related to the power of the models and to how researchers were able to jailbreak them into providing responses that enable a user to develop malicious software.

Fable 5 and Mythos 5 were banned on June 12, as the US government implemented export controls requiring Anthropic to restrict access to both bleeding-edge models to only verifiable American citizens. Anthropic explained that, since the export ban took effect immediately and It didn't have a way to verify its customer base in real time, the company shut down Mythos 5 and Fable 5 for all users.

However, according to this recent announcement, Anthropic and the US government have reached an agreement, and Fable 5 will return to all Claude users tomorrow. For Pro, Max, Team, and select Enterprise plans, Fable 5 will be included within usage limits for up to 50% of weekly usage limits through to July 7. After July 7, Fable 5 will be restricted to usage credits, meaning it will only be available via API billing and will no longer be accessible to those on the aforementioned subscriptions.

So, what has changed for the US government to lift the export ban? Anthropic has agreed to work with the US government on several fronts, including government access and evaluation of all AI models before they are made public, rapid information sharing on safeguards for models, and expedited government awareness of any model vulnerabilities.
