Common Node Types

Loaders:

• Load Checkpoint — base model (SD1.5/SDXL/SD3)
• Load LoRA — fine-tuned styles/characters
• Load VAE — decoder/encoder
• Load ControlNet — pose/edge/depth control
• Load IPAdapter — image-prompt conditioning

Latent:

• Empty Latent Image — resolution, batch size
• VAE Encode — image → latent space
• VAE Decode — latent → image
• KSampler — the core sampling node

Image:

• Save Image — outputs to ComfyUI/output/
• Preview Image — show in UI
• Load Image — input image
• Image Scale — resize

KSampler Quick Settings

Steps:      20-30 (fast), 40-50 (quality)
CFG:        7.0 (default), 3.0-5.0 (creative), 10+ (strict)
Sampler:    DPM++ 2M Karras (best balance)
             Euler (fast), DDIM (reproducible)
Scheduler:  Karras (default), exponential, simple
Denoise:    1.0 (txt2img), 0.4-0.7 (img2img)

Workflow Tips

VRAM optimization: Use --lowvram or --novram flags. Set batch size to 1. Enable --fast mode.

Workflow as JSON: Save workflows via the Save button (floppy disk icon). Share the JSON — it embeds all node positions and settings.

Custom nodes: Drop into ComfyUI/custom_nodes/. Popular packs: ComfyUI-Manager, Efficiency Nodes, WAS Node Suite.

Model folders:
