Python: Bug: Python - Semantic Kernel Realtime isn't supporting the GA versions of Azure OpenAI realtime models
Describe the bug When attempting to use any of the new GA models in Azure OpenAI for Semantic Kernel Realtime, you're faced with an error
To Reproduce Steps to reproduce the behavior:
- Deploy a GA model from Azure OpenAI
- give any name that's not in this list ('gpt-4o-realtime-preview', 'gpt-4o-realtime-preview-2024-10-01', 'gpt-4o-realtime-preview-2024-12-17', 'gpt-4o-realtime-preview-2025-06-03', 'gpt-4o-mini-realtime-preview' or 'gpt-4o-mini-realtime-preview-2024-12-17')
- Run a code sample from https://learn.microsoft.com/en-us/semantic-kernel/concepts/ai-services/realtime?pivots=programming-language-python or https://github.com/Azure-Samples/AI-Gateway/blob/main/labs/realtime-mcp-agents/realtime-mcp-agents.ipynb
- See error
session.model Input should be 'gpt-4o-realtime-preview', 'gpt-4o-realtime-preview-2024-10-01', 'gpt-4o-realtime-preview-2024-12-17', 'gpt-4o-realtime-preview-2025-06-03', 'gpt-4o-mini-realtime-preview' or 'gpt-4o-mini-realtime-preview-2024-12-17' [type=literal_error, input_value='gpt-realtime', input_type=str] For further information visit https://errors.pydantic.dev/2.11/v/literal_error
Expected behavior It should work as expected as it used to whilst we still had preview models
Additional context Workaround, at deployment time, name the GA model as gpt-4o-realtime-preview
Platform
- Language: Python
- Source: semantic-kernelrealtime, semantic-kernel-1.37.0
