When does this happen?
IF When calling Azure GPT-5 (gpt-5-chat-2025-08-07) via LiteLLM with `temperature=0.0`, the request fails because GPT-5 reasoning models only support temperature=1.
How others solved it
THEN Set temperature to 1, or use `drop_params=True` to automatically drop unsupported parameters. Alternatively, add `"allowed_openai_params": ["temperature"]` to the request if you need to pass temperature (though it will be ignored).
litellm_settings: drop_params: true
