Vercel has suspended access to Claude Fable 5 on AI Gateway for all users, citing compliance with a US Government directive. The suspension is indefinite. Anthropic's own notice at anthropic.com/news/fable-mythos-access is the originating policy document worth reading.
No timeline exists for restoration. Vercel has confirmed no knowledge of if or when the model returns to the platform.
Other Anthropic models remain available through AI Gateway. If your stack depends on Fable 5 specifically, read the full Vercel changelog and the linked government directive to understand the scope of the restriction before making migration decisions.
