Get started with the Gemini API

The Gemini API and Google AI Studio help you start working with Google's latest models and turn your ideas into applications that scale.

Python

import google.generativeai as genai

genai.configure(api_key="YOUR_API_KEY")
model = genai.GenerativeModel("gemini-1.5-flash")
response = model.generate_content("Explain how AI works")
print(response.text)

Node.js

const { GoogleGenerativeAI } = require("@google/generative-ai");

const genAI = new GoogleGenerativeAI("YOUR_API_KEY");
const model = genAI.getGenerativeModel({ model: "gemini-1.5-flash" });

const prompt = "Explain how AI works";

const result = await model.generateContent(prompt);
console.log(result.response.text());

REST

curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-1.5-flash:generateContent?key=$YOUR_API_KEY" \
-H 'Content-Type: application/json' \
-X POST \
-d '{
