Failing to access "gpt-4o-realtime-preview-2024-12-17" model

Author: seratchCreated Feb 19, 2025Updated Jul 14, 2025

Hello! It seems my account can't access the gpt-4o-realtime-preview-2024-12-17 model, but it can use the gpt-4o-realtime-preview. Should this example app consistently use the gpt-4o-realtime-preview to ensure broader audiences can run it successfully?

Here is the error response with gpt-4o-realtime-preview-2024-12-17 model:

  }
}

Modifying the code this way resolved the issue for me:

I am happy to send a pull request as necessary.
