Chroma provides a convenient wrapper around JinaAI's embedding API. This embedding function runs remotely on JinaAI's servers, and requires an API key. You can get an API key by signing up for an account at JinaAI.
You can pass in an optional model_name argument, which lets you choose which Jina model to use. By default, Chroma uses jina-embedding-v2-base-en.
