This model is a running acceleration version of HelloWorld SDXL original version combined with SDXL-Lightning technology. Paired with UniPC/Eular a sampler, it can generate images in 6-8 steps, which is three times faster than the original sdxl version. After comparison, the imaging results of the Lightning version are better than the LCM or Turbo versions, with the same VRAM usage as the original HelloWorld version.

This model recommends the following image generation parameters:

Sampler: UniPC/Eular a (Important! This model is specifically adapted for UniPC/Eular a, and other samplers may not obtain the same good results)

Sampling steps: 8 steps (6~8 steps are all acceptable)

CFG scale: 1.5 (1~1.5 are all acceptable)

【Note】When performing high-resolution zooming with the Lightning version, some images may have slight pseudoshadows, and the severity of the pseudoshadows varies depending on the zooming algorithm. It has been tested that the effect is better under Eular a + BSRGAN algorithm. Below are the recommended parameters for high-resolution zooming:

Sampler and zooming algorithm: Eular a + BSRGAN

Zooming factor: 1.5x

Zooming steps: 8 steps

Zooming denoising coefficient: 0.3
