Embedding

The embedding model in LlamaIndex is responsible for creating numerical representations of text. By default, LlamaIndex will use the text-embedding-ada-002 model from OpenAI.

This can be explicitly set in the ServiceContext object.

import { OpenAIEmbedding, serviceContextFromDefaults } from "llamaindex";

const openaiEmbeds = new OpenAIEmbedding();

const serviceContext = serviceContextFromDefaults({ embedModel: openaiEmbeds });

Local Embedding

For local embeddings, you can use the HuggingFace embedding model.
