Class OracleEmbeddingModel

java.lang.Object

dev.langchain4j.model.embedding.DimensionAwareEmbeddingModel

dev.langchain4j.model.oracle.OracleEmbeddingModel

All Implemented Interfaces:

EmbeddingModel

public class OracleEmbeddingModel
extends DimensionAwareEmbeddingModel

Embed documents Use dbms_vector_chain.utl_to_embeddings to get embeddings. You can specify which provider to use such as an ONNX model or a third-party provider via a REST call. Some example preferences To use an ONNX model: { "provider": "database", "model": "database" } To use a third-party provider: { "provider": "ocigenai", "credential_name": "OCI_CRED", "url": "https://inference.generativeai.us-chicago-1.oci.oraclecloud.com/20231130/actions/embedText", "model": "cohere.embed-english-light-v3.0" }
