Model Downloader

The single most annoying part of ComfyUI is getting model files into the right directory - drop a GGUF in the wrong subfolder and your dropdown is empty, and there's no error message to help. ModelDownloader exists to kill that whole class of problem: you give it a folder name and URLs, and it downloads straight into the correct spot under ComfyUI/models/. It's the node version of "download this, save it here," except the "here" is guaranteed to be right.

How it works

You type a list with a simple format - a folder name line, then the URLs that go in it:

diffusion_models
https://huggingface.co/unsloth/Qwen-Image-2512-GGUF/resolve/main/qwen-image-2512-Q8_0.gguf
clip
https://huggingface.co/unsloth/Qwen2.5-VL-7B-Instruct-GGUF/resolve/main/Qwen2.5-VL-7B-Instruct-Q8_0.gguf

Each block maps to a subfolder under models/, and the node downloads in parallel with a configurable number of worker threads. It also checks what's already there, skipping complete files and picking up interrupted ones. Two download paths, toggled by checkboxes:

• use_hf_download - off by default, which uses plain HTTP chunked downloads (maximum compatibility, per the author's tooltip). On, it uses huggingface_hub - files stage in the HF cache first, then move into your models folder automatically.
• use_s3c - pairs with HF mode and uses the s3impleclient accelerator for faster pulls. Only works when use_hf_download is on, and only if you've installed s3impleclient.

You can also skip typing entirely: model_template has ready-made download lists for the pack's recommended models - Qwen-Edit bundles, Z-Image Turbo in GGUF/FP8/FP16 variants with VRAM tiers in the names, and an Ultraflux VAE. Selecting one overrides your manual list, which the tooltip warns you about.

Inputs and output

• download_list - the folder/URL blocks above.
• chunk_size_mb (default 10) and max_workers (default 8) - tune for your connection.
• model_template - the one-click presets.
• The rest are the two download toggles.

Output is a single status_message string telling you what got downloaded, skipped, or failed - useful for glancing at in a Show Text node.

Installing it

cd ComfyUI/custom_nodes
git clone https://github.com/dseditor/ComfyUI-ListHelper

Restart ComfyUI; find it under ListHelper/Tools. The huggingface_hub and s3impleclient packages aren't in the pack's requirements, so they install on demand only if you enable those modes - plain HTTP mode needs nothing extra. ComfyUI Manager: search "ComfyUI-ListHelper".

Where people get burned

The URL format matters. These need direct resolve/main/… file URLs from HuggingFace, not repo pages - copy the "download" link, not the model page URL. And a word of caution from the wider ecosystem's habit of downloading workflow JSONs: only run this with URLs you actually trust. A malicious node pack is how a lot of people got burned in this ecosystem, and a "model downloader" is a great place for bad actors to hide. For the legit Qwen-Edit / Z-Image templates it ships with, it's genuinely convenient - just keep your own list to repos you recognize.
