Krea 2 Turbo needs about eight passes to produce a clean image. Cut that to four and it gets blurry: fine texture goes soft and edges lose definition. This adapter, a LoRA that loads on top of the unchanged base model, was trained to put that detail back at four passes. The author reports an end-to-end render at 1024 by 1024 dropping from about 89 seconds to about 55 on the test machine, with fine-texture energy at 1.03 times the eight-step original and saturation and skin texture within a few percent of it. A vision-language judge shown the eight-step and four-step renders side by side preferred the original on only 6 of 45 pairs.
There is one dial. Strength 1.0 is the trained setting; if a stylised or high-contrast prompt comes back looking too crunchy, 0.75 softens the correction without changing the picture itself. It was trained at twelve resolutions and aspect ratios from 512 square up to 1440 square, so portrait and landscape framings are covered.
The repo is unusually honest about how it was made: which training stretches made things worse, why the shipped weights are a running average rather than the last checkpoint, and every comparison sheet at a fixed seed. Nothing here is Krea's official work; it is one person's project, and the numbers are the author's own.
