Migrating to the OpenAI Python API library 1.x

OpenAI released a new version of the OpenAI Python API library. This guide is supplemental to OpenAI's migration guide and will help bring you up to speed on the changes specific to Azure OpenAI.

Updates

• This is a new version of the OpenAI Python API library.
• Starting on November 6, 2023 pip install openai and pip install openai --upgrade will install version 1.x of the OpenAI Python library.
• Upgrading from version 0.28.1 to version 1.x is a breaking change, you'll need to test and update your code.
• Auto-retry with backoff if there's an error
• Proper types (for mypy/pyright/editors)
• You can now instantiate a client, instead of using a global default.
• Switch to explicit client instantiation
• Name changes

Known issues

• DALL-E3 is fully supported with the latest 1.x release. DALL-E2 can be used with 1.x by making the following modifications to your code.
• embeddings_utils.py which was used to provide functionality like cosine similarity for semantic text search is no longer part of the OpenAI Python API library.
• You should also check the active GitHub Issues for the OpenAI Python library.

Test before you migrate

Important

Automatic migration of your code using openai migrate is not supported with Azure OpenAI.

As this is a new version of the library with breaking changes, you should test your code extensively against the new release before migrating any production applications to rely on version 1.x. You should also review your code and internal processes to make sure that you're following best practices and pinning your production code to only versions that you have fully tested.

To make the migration process easier, we're updating existing code examples in our docs for Python to a tabbed experience:

OpenAI Python 1.x

Console

pip install openai --upgrade

OpenAI Python 0.28.1

Console

pip install openai==0.28.1

This provides context for what has changed and allows you to test the new library in parallel while continuing to provide support for version 0.28.1. If you upgrade to 1.x and realize you need to temporarily revert back to the previous version, you can always pip uninstall openai and then reinstall targeted to 0.28.1 with pip install openai==0.28.1.

Chat completions

OpenAI Python 1.x

You need to set the model variable to the deployment name you chose when you deployed the GPT-3.5-Turbo or GPT-4 models. Entering the model name results in an error unless you chose a deployment name that is identical to the underlying model name.

Python

import os
from openai import AzureOpenAI

client = AzureOpenAI(
  azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT"), 
  api_key=os.getenv("AZURE_OPENAI_API_KEY"),  
  api_version="2024-02-01"
)

response = client.chat.completions.create(
    model="gpt-35-turbo", # model = "deployment_name"
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Does Azure OpenAI support customer managed keys?"},
        {"role": "assistant", "content": "Yes, customer managed keys are supported by Azure OpenAI."},
        {"role": "user", "content": "Do other Azure AI services support this too?"}
    ]
)

print(response.choices[0].message.content)

Additional examples can be found in our in-depth Chat Completion article.

OpenAI Python 0.28.1

You need to set the engine variable to the deployment name you chose when you deployed the GPT-3.5-Turbo or GPT-4 models. Entering the model name will result in an error unless you chose a deployment name that is identical to the underlying model name.

Python

import os
import openai
openai.api_type = "azure"
openai.api_base = os.getenv("AZURE_OPENAI_ENDPOINT") 
openai.api_key = os.getenv("AZURE_OPENAI_API_KEY")
openai.api_version = "2024-02-01"

response = openai.ChatCompletion.create(
    engine="gpt-35-turbo", # engine = "deployment_name".
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Does Azure OpenAI support customer managed keys?"},
        {"role": "assistant", "content": "Yes, customer managed keys are supported by Azure OpenAI."},
        {"role": "user", "content": "Do other Azure AI services support this too?"}
    ]
)

print(response)
print(response['choices'][0]['message']['content'])

Completions

OpenAI Python 1.x

Python

import os
from openai import AzureOpenAI
    
client = AzureOpenAI(
    api_key=os.getenv("AZURE_OPENAI_API_KEY"),  
    api_version="2024-02-01",
    azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT")
)
    
deployment_name='REPLACE_WITH_YOUR_DEPLOYMENT_NAME' #This will correspond to the custom name you chose for your deployment when you deployed a model. 
    
# Send a completion call to generate an answer
print('Sending a test completion job')
start_phrase = 'Write a tagline for an ice cream shop. '
response = client.completions.create(model=deployment_name, prompt=start_phrase, max_tokens=10) # model = "deployment_name"
print(response.choices[0].text)

OpenAI Python 0.28.1

Python

import os
import openai

openai.api_key = os.getenv("AZURE_OPENAI_API_KEY")
openai.api_base = os.getenv("AZURE_OPENAI_ENDPOINT") # your endpoint should look like the following https://YOUR_RESOURCE_NAME.openai.azure.com/
openai.api_type = 'azure'
openai.api_version = '2024-02-01' # this might change in the future

deployment_name='REPLACE_WITH_YOUR_DEPLOYMENT_NAME' #This will correspond to the custom name you chose for your deployment when you deployed a model. 

# Send a completion call to generate an answer
print('Sending a test completion job')
start_phrase = 'Write a tagline for an ice cream shop. '
response = openai.Completion.create(engine=deployment_name, prompt=start_phrase, max_tokens=10)
text = response['choices'][0]['text'].replace('\n', '').replace(' .', '.').strip()
print(start_phrase+text)

Embeddings

OpenAI Python 1.x

Python

import os
from openai import AzureOpenAI

client = AzureOpenAI(
  api_key = os.getenv("AZURE_OPENAI_API_KEY"),  
  api_version = "2024-02-01",
  azure_endpoint =os.getenv("AZURE_OPENAI_ENDPOINT") 
)

response = client.embeddings.create(
    input = "Your text string goes here",
    model= "text-embedding-ada-002"  # model = "deployment_name".
)

print(response.model_dump_json(indent=2))

Additional examples including how to handle semantic text search without embeddings_utils.py can be found in our embeddings tutorial.

OpenAI Python 0.28.1

Python

import openai

openai.api_type = "azure"
openai.api_key = YOUR_API_KEY
openai.api_base = "https://YOUR_RESOURCE_NAME.openai.azure.com"
openai.api_version = "2024-02-01"

response = openai.Embedding.create(
    input="Your text string goes here",
    engine="YOUR_DEPLOYMENT_NAME"
)
embeddings = response['data'][0]['embedding']
print(embeddings)

Async

OpenAI doesn't support calling asynchronous methods in the module-level client, instead you should instantiate an async client.

Python

import os
import asyncio
from openai import AsyncAzureOpenAI

async def main():
    client = AsyncAzureOpenAI(  
      api_key = os.getenv("AZURE_OPENAI_API_KEY"),  
      api_version = "2024-02-01",
      azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT")
    )
    response = await client.chat.completions.create(model="gpt-35-turbo", messages=[{"role": "user", "content": "Hello world"}]) # model = model deployment name

    print(response.model_dump_json(indent=2))

asyncio.run(main())

Authentication

Python

from azure.identity import DefaultAzureCredential, get_bearer_token_provider
from openai import AzureOpenAI

token_provider = get_bearer_token_provider(DefaultAzureCredential(), "https://cognitiveservices.azure.com/.default")

api_version = "2024-02-01"
endpoint = "https://my-resource.openai.azure.com"

client = AzureOpenAI(
    api_version=api_version,
    azure_endpoint=endpoint,
    azure_ad_token_provider=token_provider,
)

completion = client.chat.completions.create(
    model="deployment-name",  # model = "deployment_name"
    messages=[
        {
            "role": "user",
            "content": "How do I output all files in a directory using Python?",
        },
    ],
)
print(completion.model_dump_json(indent=2))
