GPT-4 API general availability and deprecation of older models in the Completions API

Deprecation of older models in the Completions API
As part of our increased investment in the Chat Completions API and our efforts to optimize our compute capacity, in 6 months we will be retiring some of our older models using the Completions API. While this API will remain accessible, we will label it as “legacy” in our developer documentation starting today. We plan for future model and product improvements to focus on the Chat Completions API, and do not have plans to publicly release new models using the Completions API.

Starting January 4, 2024, older completion models will no longer be available, and will be replaced with the following models:

Older model New model
ada ada-002
babbage babbage-002
curie curie-002
davinci davinci-002
davinci-instruct-beta gpt-3.5-turbo-instruct
curie-instruct-beta
text-ada-001
text-babbage-001
text-curie-001
text-davinci-001
text-davinci-002
text-davinci-003
Applications using the stable model names for base GPT-3 models (ada, babbage, curie, davinci) will automatically be upgraded to the new models listed above on January 4, 2024. The new models will also be accessible in the coming weeks for early testing by specifying the following model names in API calls: ada-002, babbage-002, curie-002, davinci-002.

Developers using other older completion models (such as text-davinci-003) will need to manually upgrade their integration by January 4, 2024 by specifying gpt-3.5-turbo-instruct in the “model” parameter of their API requests. gpt-3.5-turbo-instruct is an InstructGPT-style model, trained similarly to text-davinci-003. This new model is a drop-in replacement in the Completions API and will be available in the coming weeks for early testing.

Developers wishing to continue using their fine-tuned models beyond January 4, 2024 will need to fine-tune replacements atop the new base GPT-3 models (ada-002, babbage-002, curie-002, davinci-002), or newer models (gpt-3.5-turbo, gpt-4). Once this feature is available later this year, we will give priority access to GPT-3.5 Turbo and GPT-4 fine-tuning to users who previously fine-tuned older models. We acknowledge that migrating off of models that are fine-tuned on your own data is challenging. We will be providing support to users who previously fine-tuned models to make this transition as smooth as possible.

In the coming weeks, we will reach out to developers who have recently used these older models, and will provide more information once the new completion models are ready for early testing.

Deprecation of older embeddings models
Users of older embeddings models (e.g., text-search-davinci-doc-001) will need to migrate to text-embedding-ada-002 by January 4, 2024. We released text-embedding-ada-002 in December 2022, and have found it more capable and cost effective than previous models. Today text-embedding-ada-002 accounts for 99.9% of all embedding API usage.

We recognize this is a significant change for developers using those older models. Winding down these models is not a decision we are making lightly. We will cover the financial cost of users re-embedding content with these new models. We will be in touch with impacted users over the coming days.
