TLDRBip Dance has introduced SDXL Lightning, a tool exclusive to Comfy UI that accelerates image generation. It can produce 10 24x1024 images rapidly, utilizing an SDXL model with only two sampling steps, making it faster than turbo models and adept at creating detailed close-ups. To begin, download various Luras (two-step, four-step, and eight-step files) and place them in the Comfy UI's Lora folder. Open the web UI, load a default workflow, select an SDXL model, and add a Lora loader node, choosing the two-step Lora for this demonstration. Configure the K sampler to two steps and use the ULER sampler with the SGM uniform scheduler. For enhancement, use Ultimate SD for quick upscaling with the same case sampler settings, or try Cre.ia for a free, significant boost in image detail. The video concludes with a teaser for the next tutorial on monetizing AI to create e-commerce product images.
