JinaRerankFunction

JinaRerankFunction is a class in milvus_model that takes a query and document as input and directly returns a similarity score instead of embeddings. This functionality uses the underlying Jina AI reranking model.

pymilvus.model.reranker.JinaRerankFunction

Constructor

Constructs a JinaRerankFunction for common use cases.

JinaRerankFunction(
    model_name: str = "jina-reranker-v2-base-multilingual",
    api_key: Optional[str] = None
)

Parameters:

• model_name (string)

  The name of the Jina AI reranker model to use for encoding. If you leave this parameter unspecified, jina-reranker-v2-base-multilingual will be used. For a list of available models, refer to Jina AI Rerankers.

• api_key (string)

  The API key for accessing the Jina AI API.

Examples

from pymilvus.model.reranker import JinaRerankFunction

jina_rf = JinaRerankFunction(
    model_name="jina-reranker-v2-base-multilingual", # Defaults to `jina-reranker-v2-base-multilingual`
    api_key="YOUR_JINAAI_API_KEY"
)
