How can I deploy a fine-tuned GPT model in Azure via Python without using a token (e.g., using an endpoint key instead)?

I follow Azure's tutorial on fine-tuning GPT. I follow the deployment phase.

Code:

# Deploy fine-tuned model

import json
import requests

token = '[redacted]'
subscription = '[redacted]'
resource_group = "[redacted]"
resource_name = "[redacted]"
model_deployment_name = "gpt-4o-mini-2024-07-18-ft" # Custom deployment name you chose for your fine-tuning model

deploy_params = {'api-version': "2023-05-01"}
deploy_headers = {'Authorization': 'Bearer {}'.format(token), 'Content-Type': 'application/json'}

deploy_data = {
    "sku": {"name": "standard", "capacity": 1},
    "properties": {
        "model": {
            "format": "OpenAI",
            "name": "gpt-4o-mini-2024-07-18.ft-[redacted]", #retrieve this value from the previous call, it will look like gpt-4o-mini-2024-07-18.ft-[redacted]
            "version": "1"
        }
    }
}
deploy_data = json.dumps(deploy_data)

request_url = f'https://management.azure.com/subscriptions/{subscription}/resourceGroups/{resource_group}/providers/Microsoft.CognitiveServices/accounts/{resource_name}/deployments/{model_deployment_name}'

print('Creating a new deployment...')

r = requests.put(request_url, params=deploy_params, headers=deploy_headers, data=deploy_data)

print(r)
print(r.reason)
print(r.json())

That works fine, but the token expires quickly. This annoys me. How can I deploy a fine-tuned GPT model in Azure via Python without using a token (e.g., using an endpoint key instead)?

how to deploy the finetune model? using key based authentication?.

No, it is not possible to authenticate the Management API using key-based authentication.

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.CognitiveServices/accounts/{resourceName}/deployments/{deploymentName}?api-version=2024-10-01

is a management plane operation (via Azure Resource Manager), and API key authentication is not supported for management APIs.

The above management API will work on this Azure Service principal, Azure CLI and Managed Identity Authentication.
