Krea 2 Large

Text-to-Image • krea

krea/krea-2-large

• Third-party

More than 2x 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), and expressive and artistic styles.

Usage

const response = await env.AI.run(
  'krea/krea-2-large',
  {
    prompt: 'a cinematic glass cabin beside a frozen lake at sunrise',
    aspect_ratio: '16:9',
    resolution: '1K',
  },
)
console.log(response)
