Azure OpenAI Service is powered by a diverse set of models with different capabilities and price points. Model availability varies by region and cloud. For Azure Government model availability, please refer to Azure Government OpenAI Service.
Models | Description |
---|---|
GPT-4o & GPT-4o mini & GPT-4 Turbo | The latest most capable Azure OpenAI models with multimodal versions, which can accept both text and images as input. |
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 | A series of models that can generate original images from natural language. |
Whisper | A series of models in preview that can transcribe and translate speech to text. |
Text to speech (Preview) | A series of models in preview that can synthesize text to speech. |
GPT-4o integrates text and images in a single model, enabling it to handle multiple data types simultaneously. This multimodal approach enhances accuracy and responsiveness in human-computer interactions. GPT-4o matches GPT-4 Turbo in English text and coding tasks while offering superior performance in non-English languages and vision tasks, setting new benchmarks for AI capabilities.
GPT-4o and GPT-4o mini are available for standard and global-standard model deployment.
You need to create or use an existing resource in a supported standard or global standard region where the model is available.
When your resource is created, you can deploy the GPT-4o models. If you are performing a programmatic deployment, the model names are:
gpt-4o
Version2024-08-06
gpt-4o
, Version2024-05-13
gpt-4o-mini
Version2024-07-18
GPT-4 Turbo is a large multimodal model (accepting text or image inputs and generating text) that can solve difficult problems with greater accuracy than any of OpenAI's previous models. Like GPT-3.5 Turbo, and older GPT-4 models GPT-4 Turbo is optimized for chat and works well for traditional completions tasks.
[!INCLUDE GPT-4 Turbo]
GPT-4 is the predecessor to GPT-4 Turbo. Both the GPT-4 and GPT-4 Turbo models have a base model name of gpt-4
. You can distinguish between the GPT-4 and Turbo models by examining the model version.
gpt-4
Version0314
gpt-4
Version0613
gpt-4-32k
Version0613
You can see the token context length supported by each model in the model summary table.
- These models can only be used with the Chat Completion API.

Caution
We don't recommend using preview models in production. We will upgrade all deployments of preview models to either future preview versions or to the latest stable/GA version. Models designated preview do not follow the standard Azure OpenAI model lifecycle.
- GPT-4 version 0125-preview is an updated version of the GPT-4 Turbo preview previously released as version 1106-preview.
- GPT-4 version 0125-preview completes tasks such as code generation more completely compared to gpt-4-1106-preview. Because of this, depending on the task, customers may find that GPT-4-0125-preview generates more output compared to the gpt-4-1106-preview. We recommend customers compare the outputs of the new model. GPT-4-0125-preview also addresses bugs in gpt-4-1106-preview with UTF-8 handling for non-English languages.

Important
gpt-4
versions 1106-Preview, 0125-Preview, and vision-preview will be upgraded with a stable version ofgpt-4
in the future. Deployments ofgpt-4
versions 1106-Preview, 0125-Preview, and vision-preview set to "Auto-update to default" and "Upgrade when expired" will start to be upgraded after the stable version is released. For each deployment, a model version upgrade takes place with no interruption in service for API calls. Upgrades are staged by region and the full upgrade process is expected to take 2 weeks. Deployments ofgpt-4
versions 1106-Preview, 0125-Preview, and vision-preview set to "No autoupgrade" will not be upgraded and will stop operating when the preview version is upgraded in the region. See Azure OpenAI model retirements and deprecations for more information on the timing of the upgrade.
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.

1 This model will accept requests > 4,096 tokens. It is not recommended to exceed the 4,096 input token limit as the newer version of the model are capped at 4,096 tokens. If you encounter issues when exceeding 4,096 input tokens with this model this configuration is not officially supported.
text-embedding-3-large
is the latest and most capable embedding model. Upgrading between embeddings models is not possible. In order to move from using text-embedding-ada-002
to text-embedding-3-large
you would need to generate new embeddings.
text-embedding-3-large
text-embedding-3-small
text-embedding-ada-002
In testing, OpenAI reports both the large and small third generation embeddings models offer better average multi-language retrieval performance with the MIRACL benchmark while still maintaining performance for English tasks with the MTEB benchmark.
Evaluation Benchmark | text-embedding-ada-002 |
text-embedding-3-small |
text-embedding-3-large |
---|---|---|---|
MIRACL average | 31.4 | 44.0 | 54.9 |
MTEB average | 61.0 | 62.3 | 64.6 |
The third generation embeddings models support reducing the size of the embedding via a new dimensions
parameter. Typically larger embeddings are more expensive from a compute, memory, and storage perspective. Being able to adjust the number of dimensions allows more control over overall cost and performance. The dimensions
parameter is not supported in all versions of the OpenAI 1.x Python library, to take advantage of this parameter we recommend upgrading to the latest version: pip install openai --upgrade
.
OpenAI's MTEB benchmark testing found that even when the third generation model's dimensions are reduced to less than text-embeddings-ada-002
1,536 dimensions performance remains slightly better.
The DALL-E models generate images from text prompts that the user provides. DALL-E 3 is generally available for use with the REST APIs. DALL-E 2 and DALL-E 3 with client SDKs are in preview.
The Whisper models 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.
The OpenAI text to speech models, currently in preview, can be used to synthesize text to speech.
You can also use the OpenAI text to speech voices via Azure AI Speech. To learn more, see OpenAI text to speech voices via Azure OpenAI Service or via Azure AI Speech guide.

Important
The NEW gpt-35-turbo (0125)
model has various improvements, including higher accuracy at responding in requested formats and a fix for a bug which caused a text encoding issue for non-English language function calls.
GPT-3.5 Turbo is used with the Chat Completion API. GPT-3.5 Turbo version 0301 can also be used with the Completions API, though this is not recommended. GPT-3.5 Turbo versions 0613 and 1106 only support the Chat Completions API.
GPT-3.5 Turbo version 0301 is the first version of the model released. Version 0613 is the second version of the model and adds function calling support.
