I dont understand how this article is presenting this new model as a competitor of SD. SD already has LCM support, there is StreamDiffusion which you can run on your computer to see near live img2img. There is Control Net, Turbo and lots of other things community has been doing on SD to improve performance. This article is very thin on details of PixArt and it only made me think this is just a fork/variation of SD instead of a new thing like SD.

Yes, it's mostly a new training technique (that is impressive: "PIXART-α only takes 10.8% of Stable Diffusion v1.5's training time"). I'm not really sure if it really improves the image quality over SDXL, but it may a bit: https://pixart-alpha.github.io https://pixart-alpha.github.io
