WSJ says Fable 5 and Mythos 5 users lose access after Trump administration security-risk declaration

The report says the administration labeled the models security risks, cutting off access for users of both systems and raising fresh questions about AI controls and national security.

Fact Check
The WSJ article 'Anthropic Halts Access to Top AI Models After U.S. Ban on Foreign Use' directly confirms that Anthropic cut access to Fable 5 and Mythos 5 for all users after the Trump administration, via Commerce Secretary Howard Lutnick, classified the models as security risks and imposed export restrictions. Axios independently corroborates these facts, including the letter to CEO Dario Amodei and Anthropic's response cutting off all access. The X post's summary accurately reflects the WSJ reporting it attributes the claim to.
