Chroma provides a convenient wrapper around Chroma Cloud’s Splade sparse embedding API. This embedding function runs remotely on Chroma Cloud’s servers, and requires a Chroma API key. You can get an API key by signing up for an account at Chroma Cloud.

Sparse embeddings are useful for retrieval tasks where you want to match on specific keywords or terms, rather than semantic similarity.

This embedding function relies on the httpx python package, which you can install with pip install httpx.

    from chromadb.utils.embedding_functions import ChromaCloudSpladeEmbeddingFunction, ChromaCloudSpladeEmbeddingModel
    import os

    os.environ["CHROMA_API_KEY"] = "YOUR_API_KEY"
    splade_ef = ChromaCloudSpladeEmbeddingFunction(
        model=ChromaCloudSpladeEmbeddingModel.SPLADE_PP_EN_V1
    )

    texts = ["Hello, world!", "How are you?"]
    sparse_embeddings = splade_ef(texts)
    ```

You can optionally pass in a `model` argument. By default, Chroma uses `prithivida/Splade_PP_en_v1`.
