Azure OpenAI Service model deprecations and retirements

  • Article

Overview

Azure OpenAI Service models are continually refreshed with newer and more capable models. As part of this process, we deprecate and retire older models. This document provides information about the models that are currently available, deprecated, and retired.

Terminology

  • Deprecation
    • When a model is deprecated, it's no longer available for new customers. It continues to be available for use by customers with existing deployments until the model is retired.
  • Retirement
    • When a model is retired, it's no longer available for use. Azure OpenAI Service deployments of a retired model always return error responses.

Notifications

Azure OpenAI notifies customers of active Azure OpenAI Service deployments for models with upcoming retirements. We notify customers of upcoming retirements as follows for each deployment:

  1. At model launch, we programmatically designate a "not sooner than" retirement date (typically one year out).
  2. At least 60 days notice before model retirement for Generally Available (GA) models.
  3. At least 30 days notice before preview model version upgrades.

Retirements are done on a rolling basis, region by region.

Model availability

  1. At least one year of model availability for GA models after the release date of a model in at least one region worldwide
  2. For global deployments, all future model versions starting with gpt-4o and gpt-4 0409 will be available with their (N) next succeeding model (N+1) for comparison together.
  3. Customers have 60 days to try out a new GA model in at least one global, or standard region, before any upgrades happen to a newer GA model.

Considerations for the Azure public cloud

Be aware of the following:

  1. All model version combinations will not be available in all regions.
  2. Model version N and N+1 might not always be available in the same region.
  3. GA model version N might upgrade to a future model version N+X in some regions based on capacity limitations, and without the new model version N+X separately being available to test in the same region. The new model version will be available to test in other regions before any upgrades are scheduled.
  4. Preview model versions and GA versions of the same model won't always be available to test together in the same region. There will be preview and GA versions available to test in different regions.
  5. We reserve the right to limit future customers using a particular region to balance service quality for existing customers.
  6. As always at Microsoft, security is of the utmost importance. If a model or model version is found to have compliance or security issues, we reserve the right to invoke the need to do emergency retirements. See the terms of service for more information.

Special considerations for Azure Government clouds

  1. Global standard deployments won't be available in government clouds.
  2. Not all models or model versions available in commercial / public cloud will be available in government clouds.
  3. In the Azure Government clouds, we intend to support only one version of a given model at a time.
    1. For example only one version of gpt-35-turbo 0125 and gpt-4o (2024-05-13).
  4. There will however be a 30 day overlap between new model versions, where more than two will be available.
    1. For example if gpt-35-turbo 0125 or gpt-4o (2024-05-13) is updated to a future version, or
    2. for model family changes beyond version updates, such as when moving from gpt-4 1106-preview to gpt-4o (2024-05-13).

Who is notified of upcoming retirements

Azure OpenAI notifies those who are members of the following roles for each subscription with a deployment of a model with an upcoming retirement.

  • Owner
  • Contributor
  • Reader
  • Monitoring contributor
  • Monitoring reader

How to get ready for model retirements and version upgrades

To prepare for model retirements and version upgrades, we recommend that customers test their applications with the new models and versions and evaluate their behavior. We also recommend that customers update their applications to use the new models and versions before the retirement date.

For more information on the model evaluation process, see the Getting started with model evaluation guide.

For information on the model upgrade process, see How to upgrade to a new model or version.

For more information on how to manage model upgrades and migrations for provisioned deployments, see Managing models on provisioned deployment types

Current models

Note

Not all models go through a deprecation period prior to retirement. Some models/versions only have a retirement date.

Fine-tuned models are subject to the same deprecation and retirement schedule as their equivalent base model.

These models are currently available for use in Azure OpenAI Service.

1 We'll notify all customers with these preview deployments at least 30 days before the start of the upgrades. We'll publish an upgrade schedule detailing the order of regions and model versions that we'll follow during the upgrades, and link to that schedule from here.

Important

Vision enhancements preview features including Optical Character Recognition (OCR), object grounding, video prompts will be retired and no longer available once gpt-4 Version: vision-preview is upgraded to turbo-2024-04-09. If you're currently relying on any of these preview features, this automatic model upgrade will be a breaking change.
