I've been bugging them about this for a while. There are repos that contain multiple model weights in a single repo which means adding up the file sizes won't work universally, but I'd still find it useful to have a "repo size" indicator somewhere.

I ended up building my own tool for that: https://tools.simonwillison.net/huggingface-storage

HF does this for ggufs, and it’ll show you what quantizations will work on the GPU(s) you’ve selected. Hopefully that feature gets expanded to support more model types.

I've been wondering this for literally years now...

Huggingface is just a git hosting service, like github. You can add up the sizes of all the files in the directory yourself
