All Implemented Interfaces:

EmbeddingModel, TokenCountEstimator

public class BgeSmallEnV15EmbeddingModel
extends AbstractInProcessEmbeddingModel

BAAI bge-small-en-v1.5 embedding model that runs within your Java application's process.

Maximum length of text (in tokens) that can be embedded at once: unlimited. However, while you can embed very long texts, the quality of the embedding degrades as the text lengthens. It is recommended to embed segments of no more than 512 tokens long.

Embedding dimensions: 384

It is recommended to add "Represent this sentence for searching relevant passages:" prefix to a query.
