SDXL Lightning: Achieve Flash Speed Image Rendering in Just 2 Steps (ComfyUI)
TLDRBip dance has introduced SDXL Lightning, a tool exclusive to Comfy UI that significantly accelerates image generation. This innovative tool can produce up to 10 24x1024 images, utilizing an SDXL model with only two sampling steps, making it faster than turbo models and adept at rendering detailed close-ups. To use SDXL Lightning, download the Lora files (two-step, four-step, and eight-step) and place them into the Comfy UI's Lora folder. Select an SDXL model and a two-step Lora for your project, then configure the K sampler settings to two steps and the ULER sampler with the SGM uniform scheduler. The tool delivers near-instant image rendering, as demonstrated on an RTX 360. For enhanced quality, use Ultimate SD to upscale the image with the same sampler settings. Alternatively, for further detail improvement, try using Cre.ia, a free service that can significantly boost image detail. The tutorial concludes with a teaser for the next video, which will focus on monetizing AI for e-commerce product image creation.

Q & A
What is SDXL Lightning and how does it benefit users?
-SDXL Lightning is a tool released by bip dance that significantly speeds up the image generation process. It is exclusive to Comfy UI and can create detailed close-up shots using an SDXL model with just two sampling steps, making it faster than turbo models.
What are the steps to get started with SDXL Lightning in Comfy UI?
-To get started, download different versions of Luras (two-step, four-step, and eight-step files) and place them into your Lora folder for Comfy UI. Then, open your web UI, load up a default workflow, pick an SDXL model, and add a Lora loader node with the two-step Lora for now.
How does the K sampler settings and CFG influence the rendering process?
-In the K sampler settings, you should stick with two steps. For CFG, use the ULER sampler and select the SGM uniform scheduler. These settings help in achieving faster and detailed image rendering.
What is the prompt used in the demo and how quickly does the image come to life?
-The prompt used in the demo is 'photograph of a beautiful Moroccan woman wearing a robe'. When you hit 'Q', the image comes to life almost instantly, especially when running on an RTX 360.
How can the final image be further improved?
-The final image can be further improved by using Ultimate SD, which upscales the image quickly using the same case sampler settings, making the result even more stunning.
What is the role of a refiner in the future of image rendering?
-A refiner in the future could be used to enhance image quality even further, providing additional improvements to the already detailed images produced by the SDXL Lightning tool.
How can one use an alternative enhancement service like Cre.ia?
-To use Cre.ia, create an account, select the enhancer, upload your image, adjust the settings, and use a positive prompt. This service can significantly boost the detail of your images.
What is the next topic that will be covered in the upcoming video?
-The next video will show how to make money using AI by creating product images for e-commerce businesses.
What kind of images can SDXL Lightning create?
-SDXL Lightning can create detailed close-up shots and is particularly good at producing high-quality images with a focus on intricate details.
What is the recommended hardware for running SDXL Lightning?
-The script mentions that the demonstration was run on an RTX 360, implying that a high-performance graphics card like the RTX series is recommended for optimal performance.
How many versions of Luras are mentioned in the script?
-Three versions of Luras are mentioned: two-step, four-step, and eight-step.
What is the ULER sampler and how is it used in the process?
-The ULER sampler is a component used in the CFG settings of the rendering process. It is selected along with the SGM uniform scheduler to help in achieving faster and more detailed image rendering.
What does the acronym 'RTX' stand for and what is its relevance in this context?
-RTX stands for 'Real-Time Raytracing', a technology developed by NVIDIA for their high-end graphics cards. It is relevant as it indicates the level of hardware used to achieve fast rendering speeds with SDXL Lightning.
