Genkit

Genkit is a framework for building AI-powered applications. It provides open source libraries for Node.js and Go, along with tools to help you debug and iterate quickly.

Prerequisites

This guide assumes that you're familiar with building applications with Node.js.

To complete this quickstart, make sure that your development environment meets the following requirements:

• Node.js v20+
• npm

Install Genkit dependencies

Install the following Genkit dependencies to use Genkit in your project:

• genkit provides Genkit core capabilities.
• @genkit-ai/googleai provides access to the Google AI Gemini models. Check out other plugins: https://www.npmjs.com/search?q=keywords:genkit-plugin

npm install genkit @genkit-ai/googleai

Make your first request

Get started with Genkit in just a few lines of simple code.

// import the Genkit and Google AI plugin libraries
import { gemini15Flash, googleAI } from '@genkit-ai/googleai';
import { genkit } from 'genkit';

// configure a Genkit instance
const ai = genkit({
  plugins: [googleAI()],
  model: gemini15Flash, // set default model
});

(async () => {
  // make a generation request
  const { text } = await ai.generate('Hello, Gemini!');
  console.log(text);
})();

Next steps

Now that you’re set up to make model requests with Genkit, learn how to use more Genkit capabilities to build your AI-powered apps and workflows. To get started with additional Genkit capabilities, see the following guides:

• Developer tools: Learn how to set up and use Genkit’s CLI and developer UI to help you locally test and debug your app.
• Generating content: Learn how to use Genkit’s unified generation API to generate text and structured data from any supported model.
• Creating flows: Learn how to use special Genkit functions, called flows, that provide end-to-end observability for workflows and rich debugging from Genkit tooling.
• Managing prompts: Learn how Genkit helps you manage your prompts and configuration together as code.
