Fable 5 Model Not Available

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

“We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.”

I check Cursor/Anthropic status and it looks okay. Restarted a few tries. Re-tried a few times. Is this just temporary from crazy demand? Or is this specific to the work I’m doing? (I assume it’s the former but want to double check)

Steps to Reproduce

  1. Change Model to Fable 5
  2. Provide a prompt to work on code.

Operating System

MacOS

Version Information

Version: 3.7.21

For AI issues: which model did you use?

Does this stop you from using Cursor

Yes - Cursor is unusable

Hi! Thanks for the report. We’re digging into this, it seems to be an unexpected error that occurs with how the thinking steps of Fable 5 are formatted. This becomes unrecoverable in the conversation, so any subsequent turns in the same convo won’t work. Please try a new convo, if that doesn’t work, please switch models temporarily. We’ll let you know when we have a clearer resolution.

Thanks :frowning: do I get a refund for the usage.

+1 i am expereinecing this

+1 — same issue on fresh sessions, still failing on simple messages with Fable

Same! This is super disruptive. Wastes time and money. Im not going to finish this project witha any other model. I spend thousand of dollars a month on Cursor. WOuld appereciate a refund and or credits. Heres what I copied from the error. ALso could not login to the forum using my account so I created a new account with the same email for forums i guess..

Hey @Erik_Dahl @J_Kauffman @John_Houston

Fable is currently unavailable as per US government citation.

I just upgraded to the Ultra plan to use Fable for a new project. I need to downgrade and be refunded please.

Mine says it was disabled by anthropic.

Hey all.

Let’s keep any discussion about the new restrictions on Fable over here.
