ComfyUI: Generating a medieval warrior with batch processing

Demo summary
Demonstrates generating multiple images of a medieval warrior by increasing the batch size in the Empty Latent Image node.
Step-by-step
- Load the checkpoint node
- Configure the prompt for a medieval warrior
- Go to the Empty Latent Image node
- Increase the batch size to 2
- Click Queue Prompt
- Right-click the generated image in the Preview Image node
- Select Save Image
Watch out for
- The Preview Image node does not automatically save images to your storage.
Tips
- Note that ComfyUI is efficient because it only re-runs nodes where parameters have changed, keeping the rest in memory.
