batchSize

batchSize: number = 48

The maximum number of documents to embed in a single request. This is limited by the Cohere API to a maximum of 96.

caller

caller: AsyncCaller

The async caller should be used by subclasses to make any async calls, which will thus benefit from the concurrency and retry logic.

modelName

modelName: string = "small"

Methods

embedDocuments

  • embedDocuments(texts): Promise<number[][]>

  • Generates embeddings for an array of texts.

    Parameters

    • texts: string[]

      An array of strings to generate embeddings for.

    Returns Promise<number[][]>

    A Promise that resolves to an array of embeddings.

embedQuery

  • embedQuery(text): Promise<number[]>

  • Generates an embedding for a single text.

    Parameters

    • text: string

      A string to generate an embedding for.

    Returns Promise<number[]>

    A Promise that resolves to an array of numbers representing the embedding.
