Endpointsv2/embed

Embed API (v2)

This endpoint returns text embeddings. An embedding is a list of floating point numbers that captures semantic information about the text that it represents. Embeddings can be used to create text classifiers as well as empower semantic search. To learn more about embeddings, see the embedding page. If you want to learn more how to use the embedding model, have a look at the [Semantic Search Guide](https://docs.cohere.com/docs/semantic-search).

Authentication

AuthorizationBearer

Bearer authentication of the form Bearer <token>, where token is your auth token.

Headers

X-Client-NamestringOptional
The name of the project that is making the request.

Request

modelstringRequired

ID of one of the available Embedding models.

input_typeenumRequired
Specifies the type of input passed to the model. Required for embedding models v3 and higher. - `"search_document"`: Used for embeddings stored in a vector database for search use-cases. - `"search_query"`: Used for embeddings of search queries run against a vector DB to find relevant documents. - `"classification"`: Used for embeddings passed through a text classifier. - `"clustering"`: Used for the embeddings run through a clustering algorithm. - `"image"`: Used for embeddings with image input.
Allowed values:
textslist of stringsOptional

An array of strings for the model to embed. Maximum number of texts per call is 96.

imageslist of stringsOptional
An array of image data URIs for the model to embed. Maximum number of images per call is `1`. The image must be a valid [data URI](https://developer.mozilla.org/en-US/docs/Web/URI/Schemes/data). The image must be in either `image/jpeg`, `image/png`, `image/webp`, or `image/gif` format and has a maximum size of 5MB. Image embeddings are supported with Embed v3.0 and newer models.
inputslist of objectsOptional

An array of inputs for the model to embed. Maximum number of inputs per call is 96. An input can contain a mix of text and image components.

max_tokensintegerOptional

The maximum number of tokens to embed per input. If the input text is longer than this, it will be truncated according to the truncate parameter.

output_dimensionintegerOptional

The number of dimensions of the output embedding. This is only available for embed-v4 and newer models. Possible values are 256, 512, 1024, and 1536. The default is 1536.

embedding_typeslist of enumsOptional
Specifies the types of embeddings you want to get back. Can be one or more of the following types. * `"float"`: Use this when you want to get back the default float embeddings. Supported with all Embed models. * `"int8"`: Use this when you want to get back signed int8 embeddings. Supported with Embed v3.0 and newer Embed models. * `"uint8"`: Use this when you want to get back unsigned int8 embeddings. Supported with Embed v3.0 and newer Embed models. * `"binary"`: Use this when you want to get back signed binary embeddings. Supported with Embed v3.0 and newer Embed models. * `"ubinary"`: Use this when you want to get back unsigned binary embeddings. Supported with Embed v3.0 and newer Embed models. * `"base64"`: Use this when you want to get back base64 embeddings. Supported with Embed v3.0 and newer Embed models.
truncateenumOptionalDefaults to END
One of `NONE|START|END` to specify how the API will handle inputs longer than the maximum token length. Passing `START` will discard the start of the input. `END` will discard the end of the input. In both cases, input is discarded until the remaining input is exactly the maximum input token length for the model. If `NONE` is selected, when the input exceeds the maximum input token length an error will be returned.
Allowed values:

Response

OK
idstring
embeddingsobject

An object with different embedding types. The length of each embedding type array will be the same as the length of the original texts array.

response_typeenum or null
Allowed values:
textslist of strings or null
The text entries for which embeddings were returned.
imageslist of objects or null
The image entries for which embeddings were returned.
metaobject or null
