THIS IS A PIXART SIGMA MODEL. IT WILL ONLY WORK IN UIs THAT SUPPORT PIXART SIGMA!

Comfy workflow: Simple PixArt Workflow in ComfyUI - v1.0 | Stable Diffusion Workflows | Civitai

This is 900M parameter model, so you will need to have the latest ComyUI_ExtraModels code to autodetect it OR you need to set the number of layers to 42 in Diffusers. Other UIs you will be on your own.

This model takes pixart to photorealism and hyperrealism. Trained on 50/50 curated synthetic data and real data.

Ideal settings are: DPM++ SDE GPU, CFG 2.5 - 3.0, AutoCfg node, Aligned Scheduler set to SDXL.
