All Implemented Interfaces:
dev.langchain4j.model.embedding.EmbeddingModel
public class BgeSmallEnQuantizedEmbeddingModel extends dev.langchain4j.model.embedding.onnx.AbstractInProcessEmbeddingModel
Quantized BAAI bge-small-en 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.

Uses an Executor to parallelize the embedding process. By default, uses a cached thread pool with the number of threads equal to the number of available processors. Threads are cached for 1 second.
