US eases export controls on Anthropic's Fable and Mythos AI, enabling resumed access

The US Commerce Department has lifted export controls on Anthropic's Fable and Mythos AI models, removing the export license requirement and allowing Anthropic to begin restoring access after a national-security pause. Anthropic pledged to proactively detect and address security risks and coordinate with the government on protocols for current and future models. Previously, Mythos 5 and Fable 5 were restricted with limited access to trusted US organizations, reflecting heightened oversight of powerful AI releases amid concerns about misuse by state actors.
