Groq

Usage

First, create an API key at the Groq Console. Then save it in your environment:

export GROQ_API_KEY=<your-api-key>

The initialize the Groq module.

import { Groq, serviceContextFromDefaults } from "llamaindex";

const groq = new Groq({
  // If you do not wish to set your API key in the environment, you may
  // configure your API key when you initialize the Groq class.
  // apiKey: "<your-api-key>",
});

const serviceContext = serviceContextFromDefaults({ llm: groq });

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], {
  serviceContext,
});

Query

const queryEngine = index.asQueryEngine();

const query = "What is the meaning of life?";

const results = await queryEngine.query({
  query,
});

Full Example

import fs from "node:fs/promises";

import {
  Document,
  Groq,
  VectorStoreIndex,
  serviceContextFromDefaults,
} from "llamaindex";

async function main() {
  // Create an instance of the LLM
  const groq = new Groq({
    apiKey: process.env.GROQ_API_KEY,
  });

  // Create a service context
  const serviceContext = serviceContextFromDefaults({ llm: groq });

  // Load essay from abramov.txt in Node
  const path = "node_modules/llamaindex/examples/abramov.txt";
  const essay = await fs.readFile(path, "utf-8");
  const document = new Document({ text: essay, id_: "essay" });

  // Load and index documents
  const index = await VectorStoreIndex.fromDocuments([document], {
    serviceContext,
  });

  // get retriever
  const retriever = index.asRetriever();

  // Create a query engine
  const queryEngine = index.asQueryEngine({
    retriever,
  });

  const query = "What is the meaning of life?";

  // Query
  const response = await queryEngine.query({
    query,
  });

  // Log the response
  console.log(response.response);
}

await main();
