Azure OpenAI Service models
Azure OpenAI Service is powered by a diverse set of models with different capabilities and price points. Model availability varies by region. For GPT-3 and other models retiring in July 2024, see Azure OpenAI Service legacy models.
| Models | Description |
|---|---|
| GPT-4 | A set of models that improve on GPT-3.5 and can understand and generate natural language and code. |
| GPT-3.5 | A set of models that improve on GPT-3 and can understand and generate natural language and code. |
| Embeddings | A set of models that can convert text into numerical vector form to facilitate text similarity. |
| DALL-E (Preview) | A series of models in preview that can generate original images from natural language. |
| Whisper (Preview) | A series of models in preview that can transcribe and translate speech to text. |
GPT-4 and GPT-4 Turbo Preview
GPT-4 can solve difficult problems with greater accuracy than any of OpenAI's previous models. Like GPT-3.5 Turbo, GPT-4 is optimized for chat and works well for traditional completions tasks. Use the Chat Completions API to use GPT-4. To learn more about how to interact with GPT-4 and the Chat Completions API check out our in-depth how-to.

You can see the token context length supported by each model in the model summary table.
GPT-3.5
GPT-3.5 models can understand and generate natural language or code. The most capable and cost effective model in the GPT-3.5 family is GPT-3.5 Turbo, which has been optimized for chat and works well for traditional completions tasks as well. GPT-3.5 Turbo is available for use with the Chat Completions API. GPT-3.5 Turbo Instruct has similar capabilities to text-davinci-003 using the Completions API instead of the Chat Completions API. We recommend using GPT-3.5 Turbo and GPT-3.5 Turbo Instruct over legacy GPT-3.5 and GPT-3 models.

Embeddings
Important
We strongly recommend using text-embedding-ada-002 (Version 2). This model/version provides parity with OpenAI's text-embedding-ada-002. To learn more about the improvements offered by this model, please refer to OpenAI's blog post. Even if you are currently using Version 1 you should migrate to Version 2 to take advantage of the latest weights/updated token limit. Version 1 and Version 2 are not interchangeable, so document embedding and document search must be done using the same version of the model.
The previous embeddings models have been consolidated into the following new replacement model:
text-embedding-ada-002
DALL-E (Preview)
The DALL-E models, currently in preview, generate images from text prompts that the user provides.
Whisper (Preview)
The Whisper models, currently in preview, can be used for speech to text.
You can also use the Whisper model via Azure AI Speech batch transcription API. Check out What is the Whisper model? to learn more about when to use Azure AI Speech vs. Azure OpenAI Service.

GPT-4 and GPT-4 Turbo Preview models
GPT-4 and GPT-4-32k models are now available to all Azure OpenAI Service customers. Availability varies by region. If you don't see GPT-4 in your region, please check back later.
These models can only be used with the Chat Completion API.
GPT-4 version 0314 is the first version of the model released. Version 0613 is the second version of the model and adds function calling support.
See model versions to learn about how Azure OpenAI Service handles model version upgrades, and working with models to learn how to view and configure the model version settings of your GPT-4 deployments.
Note
Version 0314 of gpt-4 and gpt-4-32k will be retired no earlier than July 5, 2024. See model updates for model upgrade behavior.

1 GPT-4 Turbo Preview = gpt-4 (1106-preview). To deploy this model, under Deployments select model gpt-4. For Model version select 1106-preview. We don't recommend using this model in production. We will upgrade all deployments of this model to a future stable version. Models designated preview do not follow the standard Azure OpenAI model lifecycle.
Note
Regions where GPT-4 (0314) & (0613) are listed as available have access to both the 8K and 32K versions of the model
