OpenAI
import { OpenAI, Settings } from "llamaindex";
Settings.llm = new OpenAI({ model: "gpt-3.5-turbo", temperature: 0, apiKey: <YOUR_API_KEY> });
You can setup the apiKey on the environment variables, like:
export OPENAI_API_KEY="<YOUR_API_KEY>"
Load and index documents
For this example, we will use a single document. In a real-world scenario, you would have multiple documents to index.
const document = new Document({ text: essay, id_: "essay" });
const index = await VectorStoreIndex.fromDocuments([document]);
