   This issue might be a duplicate of existing issues. Please check:

   • AI_APICallError: The requested model is not supported. #2740: AI_APICallError: The requested model is not supported. (Similar issue with GitHub Copilot Claude models not being supported)
   • Github copilot Sonnet 4 - AI_APICallError the requested model is not supported #1125: Github copilot Sonnet 4 - AI_APICallError the requested model is not supported (Same error with Claude models through GitHub Copilot)
   • GPT-5 not yet supported? #1691: GPT-5 not yet supported? (Similar 'model not supported' error with GitHub Copilot provider)

   The error message 'The requested model is not supported' with GitHub Copilot provider appears to be a recurring issue across different model versions. These issues suggest the problem might be related to model availability/rollout timing or provider-specific model access restrictions.

   Feel free to ignore if none of these address your specific case with Claude Sonnet 4.5.
