Does GPT-5 via Azure support reasoning effort and verbosity?

Hi All,

I was having some issues trying to access some of the request parameters for the new gpt-5-chat.

I have the following code snippet

api_version= "2025-04-01-preview"

model_name = "gpt-5-chat"

client = AzureOpenAI(
    api_version=api_version,
    azure_endpoint=endpoint,
    api_key=subscription_key,
)
print('Testing client input type 1 ')
response = client.chat.completions.create(
    messages=[
        {
            "role": "system",
            "content": "You are a helpful assistant.",
        },
        {
            "role": "user",
            "content": "I am going to Paris, what should I see?",
        }
    ],
    max_tokens=16384,
    temperature=1.0,
    top_p=1.0,
    model=deployment,
    reasoning_effort = "medium"
)
print('Testing client input type 2 ')
response = client.responses.create(
    model=deployment,
    input="What is the answer to the ultimate question of life, the universe, and everything?",
    text={ "verbosity": "low"},
    reasoning={ "effort": "medium"}
)

Unfortunately i get a response

openai.BadRequestError: Error code: 400 - {'error': {'message': 'Unrecognized request argument supplied: reasoning_effort', 'type': 'invalid_request_error', 'param': None, 'code': None}}

Are the reasoning and verbosity parameters available at all with gpt-5-chat? It seems that its not accessible neither though responses or completions with the newest api version. Without calling the verbosity and resoning parameters, it works just fine.
