AI BriefingClaude Fable 5 Access Resumed on AI Gateway
Key point
Following the US government's lifting of export controls, access to the Claude Fable 5 model has resumed on AI Gateway.
Details
Following the US government's decision to lift export controls, access to Claude Fable 5, a Mythos-class model, has resumed on AI Gateway. This version is identical to the model that was available in early June, but with stronger, updated Safety Classifiers applied.
Even in common tasks like coding or debugging, the safety classifiers may trigger and cause requests to be rejected. To prevent this, using the Model Fallbacks feature is recommended. If Anthropic rejects a request, the system can automatically switch to another model in the configured order to maintain service.
Regarding data security, Anthropic does not support Zero Data Retention in order to detect misuse patterns. Prompts and outputs are retained for 30 days, but are not used for model training.
