## How ComfyUI Deep-Dive Topics works on Windows

Focused technical notes on low-VRAM flags, Hunyuan Video and Wan 2.1 pipelines, API automation, and batch rendering. Exploring specialized ComfyUI workflows, hardware scaling, and local production pipelines on Windows.

Every page in this directory focuses on practical local execution on Windows 10 and Windows 11, keeping your checkpoints, LoRAs, and generated outputs entirely on your own SSD.

Start by grabbing the current Windows build from [/download](https://comfy.ink/download), or browse the guides and node blueprints linked below.

## Key workflow principles

- Keep large `.safetensors` and `.gguf` weights inside organized `models/` subfolders or map shared directories through [extra_model_paths.yaml](https://comfy.ink/install/extra-model-paths-yaml-setup).
- Match your model precision (FP16, FP8 e4m3fn, or GGUF Q4/Q8) to your card's VRAM tier so sampling stays in GPU memory without paging to disk.
- Drag any generated PNG directly onto the [ComfyUI Studio](https://comfy.ink/studio) canvas to reload its exact node wiring, seed, and sampler values.
