Embeddings

Create an embedding

POST /openai/v1/embeddings

Creates an embedding from the supplied request.

Request Body

The request body.

Content-Type: application/json

input string | string[] | OpenAI.integer[] | OpenAI.integer[][] required

Input text to embed, encoded as a string or array of tokens. To embed multiple inputs in a single request, pass an array of strings or array of token arrays. The input must not exceed the max input tokens for the model (8192 tokens for all embedding models), cannot be an empty string, and any array must be 2048 dimensions or less. Example Python code for counting tokens. In addition to the per-input token limit, all embedding models enforce a maximum of 300,000 tokens summed across all inputs in a single request.

One of the following:

string

string[]

OpenAI.integer[]

OpenAI.integer[][]

model string | enum required

ID of the model to use. You can use the List models API to see all of your available models, or see our Model overview for descriptions of them.

Any of the following:

string

enum

text-embedding-ada-002text-embedding-3-smalltext-embedding-3-large

encoding_format enum

The format to return the embeddings in. Can be either float or base64.

floatbase64

dimensions integer

user string

A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. Learn more.

Responses

The request has succeeded.
