description	ComfyUI node-based Stable Diffusion. Use for image generation.

ComfyUI

ComfyUI is a node-based GUI for Stable Diffusion. It gives you infinite control over the generation pipeline. 2025 update (UI Overhaul) makes it more accessible.

When to Use

• Complex Workflows: Hires.fix, Inpainting, ControlNet, and Upscaling in one pipeline.
• Video: AnimateDiff and video-to-video workflows.
• Optimization: Runs on lower VRAM than WebUI (A1111).

Core Concepts

Nodes & Noodles

Connect "Load Checkpoint" -> "CLIP Text Encode" -> "KSampler" -> "VAE Decode" -> "Save Image".

Workflow Format

Workflows are saved as PNG metadata. Drag a PNG into ComfyUI to load its workflow.

Custom Nodes

Community plugins (thousands available via ComfyUI Manager).

Best Practices (2025)

Do:

• Use ComfyUI Manager: Essential for installing missing custom nodes.
• Use XY Plot: To test different parameters (CFG vs Steps) grid.
• Save Workflows: Organize your JSON/PNG workflows.

Don't:

• Don't fear the spaghetti: It looks complex, but logic is linear.
