Azure OpenAI Service legacy models

  • Article

Azure OpenAI Service offers a variety of models for different use cases. The following models are not available for new deployments beginning July 6, 2023. Deployments created prior to July 6, 2023 remain available to customers until July 5, 2024. We recommend customers migrate to the replacement models prior to the July 5, 2024 retirement.

GPT-3.5

The impacted GPT-3.5 models are the following. The replacement for the GPT-3.5 models is GPT-3.5 Turbo Instruct when that model becomes available.

  • text-davinci-002
  • text-davinci-003
  • code-davinci-002

GPT-3

The impacted GPT-3 models are the following. The replacement for the GPT-3 models is GPT-3.5 Turbo Instruct when that model becomes available.

  • text-ada-001
  • text-babbage-001
  • text-curie-001
  • text-davinci-001
  • code-cushman-001

Embedding models

The embedding models below will be retired effective July 5, 2024. Customers should migrate to text-embedding-ada-002 (version 2).

Each family includes models across a range of capability. The following list indicates the length of the numerical vector returned by the service, based on model capability:

Base Model Model(s) Dimensions
Ada 1024
Babbage 2048
Curie 4096
Davinci 12288

Similarity embedding

These models are good at capturing semantic similarity between two or more pieces of text.

Use cases Models
Clustering, regression, anomaly detection, visualization text-similarity-ada-001
text-similarity-babbage-001
text-similarity-curie-001
text-similarity-davinci-001

Text search embedding

These models help measure whether long documents are relevant to a short search query. There are two input types supported by this family: doc, for embedding the documents to be retrieved, and query, for embedding the search query.

Use cases Models
Search, context relevance, information retrieval text-search-ada-doc-001
text-search-ada-query-001
text-search-babbage-doc-001
text-search-babbage-query-001
text-search-curie-doc-001
text-search-curie-query-001
text-search-davinci-doc-001
text-search-davinci-query-001

Code search embedding

Similar to text search embedding models, there are two input types supported by this family: code, for embedding code snippets to be retrieved, and text, for embedding natural language search queries.

Use cases Models
Code search and relevance code-search-ada-code-001
code-search-ada-text-001
code-search-babbage-code-001
code-search-babbage-text-001

Model summary table and region availability

Region availability is for customers with deployments of the models prior to July 6, 2023.
