If you checked out the Photoshop extension inpainting that also used Stable Diffusion. I figured this Krita extension was just using a lower quality setting or something, since the Stable Diffusion Photoshop results looked much better. Maybe it could come down to the amount of VRAM in the machine the demos were recorded on, or something.

I'm not sure but by the looks of it, it appears to be doing only 3 iterations. On https://replicate.com/stability-ai/stable-diffusion I can only get good results with hundreds of iterations
