GPT-4o and GPT-4 Turbo

GPT-4o is the latest model from OpenAI. 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.

How do I access the GPT-4o model?

GPT-4o is 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 model. If you are performing a programmatic deployment, the model name is gpt-4o, and the version is 2024-05-13.

GPT-4 Turbo

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.

The latest GA release of GPT-4 Turbo is:

  • gpt-4 Version: turbo-2024-04-09

This is the replacement for the following preview models:

  • gpt-4 Version: 1106-Preview
  • gpt-4 Version: 0125-Preview
  • gpt-4 Version: vision-preview

Differences between OpenAI and Azure OpenAI GPT-4 Turbo GA Models

  • OpenAI's version of the latest 0409 turbo model supports JSON mode and function calling for all inference requests.
  • Azure OpenAI's version of the latest turbo-2024-04-09 currently doesn't support the use of JSON mode and function calling when making inference requests with image (vision) input. Text based input requests (requests without image_url and inline images) do support JSON mode and function calling.

Differences from gpt-4 vision-preview

  • Azure AI specific Vision enhancements integration with GPT-4 Turbo with Vision aren't supported for gpt-4 Version: turbo-2024-04-09. This includes Optical Character Recognition (OCR), object grounding, video prompts, and improved handling of your data with images.

GPT-4 Turbo provisioned managed availability

  • gpt-4 Version: turbo-2024-04-09 is available for both standard and provisioned deployments. Currently the provisioned version of this model doesn't support image/vision inference requests. Provisioned deployments of this model only accept text input. Standard model deployments accept both text and image/vision inference requests.

Region availability

For information on model regional availability consult the model matrix for standard, and provisioned deployments.

Deploying GPT-4 Turbo with Vision GA

To deploy the GA model from the Studio UI, select GPT-4 and then choose the turbo-2024-04-09 version from the dropdown menu. The default quota for the gpt-4-turbo-2024-04-09 model will be the same as current quota for GPT-4-Turbo. See the regional quota limits.

GPT-4

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 Version 0314
  • gpt-4 Version 0613
  • gpt-4-32k Version 0613

You can see the token context length supported by each model in the model summary table.

GPT-4 and GPT-4 Turbo models

  • 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.
  • GPT-4 version turbo-2024-04-09 is the latest GA release and replaces 0125-Preview, 1106-preview, and vision-preview.

Important

  • gpt-4 versions 1106-Preview, 0125-Preview, and vision-preview will be upgraded with a stable version of gpt-4 in the future. Deployments of gpt-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 of gpt-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

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.

Embeddings

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.

DALL-E

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.

Whisper

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.

Text to speech (Preview)

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.
