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 });
