Overview #
As we launch safer and more capable models, we regularly retire older models. Software relying on OpenAI models may need occasional updates to keep working. Impacted customers will always be notified by email and in our documentation along with blog posts for larger changes.
This page lists all API deprecations, along with recommended replacements.
Model deprecation notice periods #
We provide advance notice before retiring models so customers have time to plan and migrate. When we announce a model deprecation, we notify customers who are actively using the model by email and document the deprecation on this page.
Unless safety or compliance concerns require a faster timeline, we provide the following minimum notice periods before model retirement:
Generally available models: At least 6 months.Specialized variants of generally available models: At least 3 months. Examples include chat variants such asgpt-5.1-chat-latest
, Codex variants such asgpt-5.3-codex
, and deep research variants such aso3-deep-research
.Preview models: Preview models, identified bypreview
in the model name, may be retired with much shorter notice, such as 2 weeks. Examples includecomputer-use-preview
andgpt-4o-audio-preview
. We don’t recommend using preview models for business-critical production workloads unless you can migrate on short notice.
If safety or compliance concerns require us to retire a model sooner, we will provide as much notice as reasonably possible. These notice periods give customers time to evaluate recommended replacement models, test application behavior, and complete migrations before a model is no longer available. In some cases, developers may be able to provision dedicated capacity for continued access after a model’s shutdown date. To explore this option, contact our sales team.
Deprecation vs. legacy #
We use the term “deprecation” to refer to the process of retiring a model or endpoint. When we announce that a model or endpoint is being deprecated, it immediately becomes deprecated. All deprecated models and endpoints will also have a shut down date. At the time of the shut down, the model or endpoint will no longer be accessible.
We use the terms “sunset” and “shut down” interchangeably to mean a model or endpoint is no longer accessible.
We use the term “legacy” to refer to models and endpoints that no longer receive updates. We tag endpoints and models as legacy to signal to developers where we’re moving as a platform and that they should likely migrate to newer models or endpoints. You can expect that a legacy model or endpoint will be deprecated at some point in the future.
