Cohere Vectorizer

RedisVL.Vectorizers.Cohere provides CohereTextVectorizer, a batch-capable IBatchTextVectorizer backed by the Cohere v2 embed API.

Package contents

  • CohereTextVectorizer for single-input and batch embedding requests

  • CohereVectorizerOptions for request shaping

  • CohereInputType for selecting the task prefix Cohere applies to inputs

  • CohereTruncate for overflow handling

  • CohereVectorizerPackage as the package marker type

Request options

CohereVectorizerOptions currently supports:

  • InputType to select the Cohere task prefix (SearchDocument, SearchQuery, Classification, Clustering); defaults to SearchDocument

  • OutputDimension to request a specific embedding dimensionality from models that support it (for example, embed-v4.0)

  • Truncate to control overflow handling (None, Start, End)

  • ClientName to send the X-Client-Name header

  • EndpointOverride when the application needs a non-default embed endpoint

The vectorizer requests float embeddings and the default provider endpoint is https://api.cohere.com/v2/embed.

Required environment variables

The smoke test reads:

  • COHERE_API_KEY as the required provider credential

  • COHERE_EMBEDDING_MODEL as an optional model override (defaults to embed-english-v3.0)
