Please help me understand something.

I've been out of the loop with HuggingFace models.

What can you do with these models?

1. Can you download them and run them on your Laptop via JupyterLab?

2. What benefits does that get you?

3. Can you update them regularly (with new data on the internet, e.g.)?

4. Can you finetune them for a specific use case (e.g. GeoSpatial data)?

5. How difficult and time-consuming (person-hours) is it to finetune a model?

(If HuggingFace has answers to these questions, please point me to the URL. HuggingFace, to me, seems like the early days of GitHub. A small number were heavy users, but the rest were left scratching their heads and wondering how to use it.)

Granted it's a newbie question, but answers will be beneficial to a lot of us out there.
