The Interactions API is now generally available. We recommend using this API for access to all the latest features and models.

Gemini API

The Gemini API is the fastest path from prompt to production with Gemini, Veo, Nano Banana, and more. It lets you integrate these generative models into your applications to generate text and images, analyze multimodal inputs, and build conversational agents.

The Interactions API is the best way to build with Gemini API and Gemini models and agents. Learn more in the Interactions API Overview.

Python

from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3.6-flash",
    input="Explain how AI works in a few words"
)

print(interaction.output_text)

JavaScript

import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({});

const interaction = await ai.interactions.create({
  model: "gemini-3.6-flash",
  input: "Explain how AI works in a few words",
});

console.log(interaction.output_text);
