AI image generator API

One text-to-image API for 12 production image models, newest first. Same authentication, same request shape, same response format — swap the model id and nothing else changes.

Most recent addition: Nano Banana 2 Lite, added Jun 2026. We add the best image models available, each behind the request shape you already use.

Pay per request. Powering 1M+ generations daily.

import GetimgAI from "getimg-ai";

const client = new GetimgAI();

const result = await client.images.generate({
    model: "gemini-3-1-flash-lite-image",
    prompt: "Woman running across surreal green hill, bouquet of red tulips hiding her face, deep blue sky, motion blur, cinematic fashion editorial",
    aspect_ratio: "1:1",
    resolution: "1K",
    output_format: "jpeg"
  });
console.log(result.data[0].url);

Which image model should you call?

Most teams start on the current flagship and add a second model for the jobs it handles badly. Here is the short version.

Start here — newest model

Nano Banana 2 Lite, added Jun 2026. Prompt adherence and text rendering improve with almost every generation of these models, so the newest release is usually the strongest default.

Final assets

Nano Banana 2 renders at 4K, so output survives print, retina displays and aggressive cropping without an upscaling pass.

Character and brand consistency

GPT Image 2 accepts up to 10 reference images, which is what you need to hold a face, product or style steady across a whole set.

Start in 60 seconds

Install the official SDK for Node.js or Python, drop in your API key, and generate your first image. Image generation is synchronous — there is nothing to poll.

npm install getimg-ai
import GetimgAI from "getimg-ai";

const client = new GetimgAI();

const result = await client.images.generate({
    model: "gemini-3-1-flash-lite-image",
    prompt: "Woman running across surreal green hill, bouquet of red tulips hiding her face, deep blue sky, motion blur, cinematic fashion editorial",
    aspect_ratio: "1:1",
    resolution: "1K",
    output_format: "jpeg"
  });
console.log(result.data[0].url);

Image generation API FAQ

What is an AI image generator API?

It is an HTTP endpoint that turns a text prompt into an image. You POST a model id and a prompt, and the response contains the generated image plus a usage object with the exact cost of that request.

The alternative is running diffusion models on your own GPUs, which means provisioning hardware, managing model weights, handling cold starts and paying for idle capacity between requests.

Which image models are available through the API?

12 image models are live right now. The most recent additions are Nano Banana 2 Lite, Grok Imagine Image, Qwen Image 2.0. Each has its own page with parameters, code samples and pricing.

Generating video instead? See the AI video generation API.

How do you decide which image models to add?

We add the best image models available. Each one is assessed on output quality, reliability and cost before it goes into the catalog, so the list stays short enough to actually choose from.

Once a model is in, it is callable immediately — same endpoint, same request format, no SDK upgrade. Only the model id changes.

The most recent addition is Nano Banana 2 Lite, added Jun 2026.

How much does an image generation API cost?

Pricing is per image and varies by model and resolution. Current image rates run from $0.015 to $0.18 per image. There is no subscription and no minimum spend — you pay for the images you generate.

The comparison table above lists the current rate for every image model.

Can I switch between image models without rewriting my integration?

Yes. Every image model on getimg.ai uses the same endpoint, authentication and request shape. Changing model means changing one string, so moving onto a newer release does not mean reworking your integration.
