Find deprecated features and recommended replacements. 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. 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. All deprecations are listed below, with the most recent announcements at the top. On November 18th, 2025, we notified developers using On November 17th, 2025, we notified developers using On November 14th, 2025, we notified developers using DALL·E model snapshots of their deprecation and removal from the API on May 12, 2026. To improve reliability and make it easier for developers to choose the right models, we are deprecating a set of older OpenAI models with declining usage over the next six to twelve months. Access to these models will be shut down on the dates below. *For tasks that are especially latency sensitive and don't require reasoning The Realtime API Beta will be deprecated and removed from the API on February 27, 2026. There are a few key differences between the interfaces in the Realtime beta API and the recently released GA API. See the migration guide to learn more about how to migrate your current beta integration. On August 26th, 2025, we notified developers using the Assistants API of its deprecation and removal from the API one year later, on August 26, 2026. When we released the Responses API in March 2025, we announced plans to bring all Assistants API features to the easier to use Responses API, with a sunset date in 2026. See the Assistants to Conversations migration guide to learn more about how to migrate your current integration to the Responses API and Conversations API. In September, 2025, we notified developers using gpt-4o-realtime-preview models of their deprecation and removal from the API in six months. On June 10th, 2025, we notified developers using gpt-4o-realtime-preview-2024-10-01 of its deprecation and removal from the API in three months. On June 10th, 2025, we notified developers using On April 28th, 2025, we notified developers using On April 28th, 2025, we notified developers using On April 14th, 2025, we notified developers that the In April 2024 when we released the v2 beta version of the Assistants API, we announced that access to the v1 beta would be shut off by the end of 2024. Access to the v1 beta will be discontinued on December 18, 2024. See the Assistants API v2 beta migration guide to learn more about how to migrate your tool usage to the latest version of the Assistants API. On August 29th, 2024, we notified developers fine-tuning Fine-tuned models created from these base models are not affected by this deprecation, but you will no longer be able to create new fine-tuned versions with these models. On June 6th, 2024, we notified developers using On November 6th, 2023, we announced the release of an updated GPT-3.5-Turbo model (which now comes by default with 16k context) along with deprecation of Fine-tuned models created from these base models are not affected by this deprecation, but you will no longer be able to create new fine-tuned versions with these models. On August 22nd, 2023, we announced the new fine-tuning API ( On July 06, 2023, we announced the upcoming retirements of older GPT-3 and GPT-3.5 models served via the completions endpoint. We also announced the upcoming retirement of our first-generation text embedding models. They will be shut down on January 04, 2024. Pricing for the replacement Pricing for the replacement On June 13, 2023, we announced new chat model versions in the Function calling and other API updates blog post. The three original versions will be retired in June 2024 at the earliest. As of January 10, 2024, only existing users of these models will be able to continue using them.Overview
