Commerce Secretary Lutnick cleared Anthropic to redeploy Mythos 5 to trusted cyber defenders, but Fable 5 remains restricted under government order.

Anthropic disabled access to its Fable 5 and Mythos 5 models to comply with a government export control directive citing "national security authorities."

After weeks of negotiations, the White House permitted Anthropic to restore access to its most advanced AI model for a select group of US companies and government agencies.

Commerce Secretary Howard Lutnick said he "determined that appropriate safeguards are in place" to grant access to Mythos.
