THEN Use the 'reasoning' object with 'effort' key instead of the top-level 'reasoning_effort' parameter, or set 'allowed_openai_params' in the request payload to include 'reasoning_effort'. For example: pass reasoning={'effort': 'low'} or set allowed_openai_params=['reasoning_effort'] and then use reasoning_effort='low'.

chat_response = await acompletion(
    model="o4-mini",
    api_key="...",
    messages=messages,
    reasoning={"effort": "low"}
)
# Alternatively:
# chat_response = await acompletion(
#     model="o4-mini",
#     api_key="...",
#     messages=messages,
#     reasoning_effort="low",
#     allowed_openai_params=["reasoning_effort"]
# )
