Krita AI Diffusion at a glance
Checked 15 Oct 2026A plugin that brings image generation into the Krita painting app: inpainting/generative fill and expand, live painting, upscaling to 4k-8k, ControlNet, IP-Adapter style and composition transfer, and regions. It uses ComfyUI as its backend, installed automatically or your own. Models include Flux 2, Z-Image, SD 1.5, SDXL and Illustrious; licence depends on the model. Code is GPL-3.0. 6GB NVIDIA VRAM is recommended locally; an optional paid cloud uses tokens.
