As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models.
Here’s what this means for you:
Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error.
On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models.
We know this is a disruption to your workflows; we appreciate your patience and support.
I’m thrilled to share that I’ll be joining UT Austin Computer Science (@UTCompSci ) as an Assistant Professor, starting Jan 2027!
I'm recruiting PhD students for Fall 2027, postdocs, and researchers at all levels:

I’ll continue my work (https://t.co/kslxLafmya) in Human-Computer Interaction (HCI) and start the Symbiotic Interfaces Lab, where we’ll explore how computational systems & humans can co-adapt to augment human sensorimotor and cognitive abilities. 🦾🧠
