I'm thrilled to introduce the Stable Diffusion XL QR Code Art Generator, a creative tool that leverages cutting-edge Stable Diffusion techniques like SDXL and FreeU. This generator is built on the SDXL QR Pattern Controlnet model by Nacholmo, but it's versatile and compatible with SD 1.5 models and the QR_Monster ControlNet as well. However, I've achieved the best results with SDXL.

Here's how it works:

1. Enter your QR code text in the QR_Text field.

2. If the QR code isn't centered, you can align it using X and Y offsets.

3. If, for example, you want to create a business card, you can adjust the canvas resolution with width and height and position the code using X and Y offsets.

Next, enter your prompt or choose a pre-saved style from the Styler, or combine your prompt with a style.

Now, you're ready to generate your QR code. The workflow includes an automatic QR code validation feature. Optionally, you can set it to save only scannable QR codes.

If your code isn't scannable, try slightly increasing the control net weight. Be cautious, though, and find the right balance, as a too high control net weight can significantly limit the AI's creativity.

The workflow requires various custom nodes, which you can easily install via the Comfyui manager.

You can download the Styler here.
