Anthropic restores Claude Fable 5 after US restrictions lifted

Anthropic is redeploying Claude Fable 5 globally on July 1 following the lifting of US export controls. The company integrated a new cybersecurity classifier that blocks specific techniques over 99% of the time, routing flagged requests to Opus 4.8. Additionally, Anthropic collaborated with Google, Microsoft, and Amazon to propose a four-criteria jailbreak severity framework. Paid users have been granted temporary access to the model, which now features enhanced cyber safeguards to ensure operational safety.
