What is comfyui-krea2control?

This project adds a set of extra control tools for ComfyUI, a visual workflow builder for AI image generation, aimed specifically at people using the Krea 2 image model. Normally, changing how an AI image looks means rewriting your text prompt and generating again to see if it worked. This project instead gives you slider style dials that adjust an already generated image along specific visual qualities, such as how warm or cool the colors look, how much fine detail appears, and whether the image leans more literal and photographic or more painterly and stylized, without needing a full new prompt each time. Beyond the built-in dials, you can create your own custom control axis in about a second by giving the tool two short descriptions, or two images, that represent the opposite ends of a quality you want to control. The tool measures the difference between them internally and turns that into a new dial you can apply and reuse. It also reports a consistency score so you can tell whether the axis you created behaves in a clean, predictable way. Axes you create can be saved to disk and reloaded later. The pack also ships eighteen ready-made dials covering things like composition, color, lighting, rendering style, and mood, which were validated by the team that originally studied the model's internals. Setup involves dropping the folder into ComfyUI's custom nodes directory and loading Krea 2 through the standard ComfyUI loaders. The README notes that loading model files directly from Krea's own repositories, rather than pre-packaged versions, requires a couple of manual file adjustments to work correctly with ComfyUI. It is best used with the faster Krea 2 Turbo variant, where a full image re-render is quick enough that adjusting a dial feels closer to a live preview.
