Krea2｜Two-stage HD Retouching

This is an AI text-to-image application based on Krea2 Turbo two-stage latent upscaling high-definition refinement.

Users only need to input a text prompt, and the system will first generate a base image, then automatically perform latent upscaling and a second round of redrawing and refinement, ultimately outputting a clearer, more stable, and more complete high-definition image.

Unlike the standard single-pass text-to-image generation of Krea2, this process does not end after a single sampling but adopts a two-stage structure. The first stage is responsible for establishing the main subject, scene, composition, and light-shadow relationships of the image; the second stage continues refining on the upscaled latent with a lower denoise to retain the original structure while enhancing details, textures, edge clarity, and overall completeness.

The entire process is completed automatically: Krea2 Turbo model loading, Qwen3VL text encoding, Krea2 Rebalance quality enhancement, creation of a 9:16 base aspect ratio, first-stage 8-step generation, latent 1.5x upscaling, second-stage 8-step high-definition refinement, Qwen Image VAE decoding, image preview, and final saving.

The current default parameters are suitable for creating vertical cinematic posters, character covers, fantasy scene illustrations, short video covers, mobile wallpapers, concept visuals, and Krea2 image generation requiring higher-definition details.
