Krea 2 is our first foundation image model, trained completely from scratch to give you full control over the look, feel, and creative direction of every image you generate. What sets it apart:
  • Aesthetic diversity — Krea 2 can generate a wide range of styles, with particular strength in artistic and expressive directions other models tend to flatten.
  • Style transfer — the most advanced style transfer system available. Extract the style of one or many reference images and apply it to your outputs with precision.
  • Tunable creativity — creativity is an actual parameter you can adjust. At high values, the model adds aesthetic depth, interpretation, and visual richness to whatever you give it.
  • Moodboards — pass in an entire moodboard of dozens of images and Krea 2 will understand the overall creative direction, producing outputs that align with it.

Choose a variant

The Krea 2 API ships in two variants. Both support the same public request shape — the differences come down to speed, model size, training stage, and the character of the outputs they produce.

Krea 2 Medium

Smaller, faster, more cost-efficient. Extensive post-training makes outputs especially stable and consistent across generations.Strongest on: illustration, anime, painting, and other expressive or artistic styles.

Krea 2 Large

More than 2× the size of Medium, with softer post-training. Outputs are rawer, more textured, and more flexible — at its best, Large produces results Medium can’t match.Strongest on: photorealism, raw looks (motion blur, grain, low dynamic range), expressive and artistic styles.
Not sure which to start with? Use Medium for stable general-purpose output, and Large when you want the richest texture or photorealism.

Medium$0.030$0.035$0.040
Large$0.060$0.065$0.070
Combining moodboards with style references does not increase the price per generation — you pay the moodboard rate ($0.040 Medium / $0.070 Large).

Quickstart

Submit a generation request and poll for the result. All requests require a Bearer token — see API Keys & Billing if you don’t have one yet. 
// npm install @krea-ai/sdk
import { Krea } from "@krea-ai/sdk";

const krea = new Krea({ apiKey: process.env.KREA_API_KEY });

const result = await krea.subscribe("image/krea/krea-2/medium", {
  input: {
    prompt: "a cinematic glass cabin beside a frozen lake at sunrise",
    aspect_ratio: "16:9",
    resolution: "1K",
  },
});

// https://gen.krea.ai/images/80ead844-02a6-467d-ba9e-fcd401bcb9a6.png
console.log(result.data?.urls[0]);
Krea 2 Large generations can take longer to complete, so for production workloads prefer the X-Webhook-URL header over polling.

​
Creativity

creativity controls how far the model expands on what you wrote. When your prompt is short or vague, the model fills in missing pieces — style, composition, camera angle, color palette — and creativity decides how much liberty it takes.
The model renders only what you’ve explicitly described. Best for tightly art-directed prompts where every detail is already specified.
Minimal expansion. The model stays close to the literal prompt but fills in obvious gaps.
Default behavior. The model adds reasonable interpretation without straying far from the prompt’s intent.
Strong expansion. The model takes meaningful creative liberty with style, mood, and aesthetics — best for short or open-ended prompts where you want the model to surprise you.

Feature deep-dives

Style transfer

Extract the style of one or many reference images and apply it to your outputs with tunable strength.

Moodboards

Reference a Krea moodboard to set the overall visual direction — palette, texture, mood, and composition.

Generative sliders

Steer intensity, complexity, and movement of every generation without rewriting your prompt.

​
Open source

Krea 2 is also available as an open-source release if you’d rather self-host or fine-tune the model instead of (or alongside) calling the hosted API. Two checkpoints are published on Hugging Face:
  • Krea 2 RAW — the undistilled base checkpoint. Diverse and malleable, intended for fine-tuning, post-training, and LoRA training.
  • Krea 2 Turbo — an 8-step distilled checkpoint built for fast text-to-image inference. LoRAs trained on RAW are designed to apply cleanly on Turbo.

Licensing

The open-source release ships under two license tracks:
  • Community License — free, non-exclusive use for research, personal, and non-commercial projects, plus commercial use under a revenue threshold. Subject to the Acceptable Use Policy.
  • Commercial License — enterprise terms for commercial use that exceeds the Community License revenue threshold. Contact opensource@krea.ai.
The hosted Krea 2 API documented on this page is governed by the standard API terms — you don’t need to accept the open-source license to call krea-2/medium or krea-2/large.
