ComfyUI: Fast image generation with Flux Schnell

Demo summary

The user switches to the Flux Schnell model and reduces the sampling steps to four to demonstrate high-speed image generation.

Step-by-step

  1. Remove any existing batching or denoising nodes
  2. Add an Empty Latent Image node
  3. Load the Flux Schnell model
  4. Set the sampling steps to 4
  5. Leave the weighting types at default
  6. Click Queue Prompt to generate the images

Options

  • Adjust weighting types
  • Increase batch size to generate multiple images simultaneously

Watch out for

  • The Schnell model is approximately 18GB and takes time to load initially
  • Image quality is slightly lower than the Flux Dev model

Tips

  • Use the Schnell model for rapid idea exploration or video-like generation
  • Expect faster performance after the model is cached following the first run
  • Be careful not to double-click the prompt button as it may restart the generation process

Highlights

this model works pretty well it's pretty cool
