You don't seem to offer viable GPU options - or maybe the pricing page is not up to date?

The GPU add-on cost is about 7.50$ per hour for a 12 GB K80 (which has 24GB, so you share it? Also, it's from 8? years ago?). As an add-on, other vendors would give you V100s (possibly multiple ones).

I am pretty sure that's not actually what you are offering, because that would be ridiculous. So you probably want to update your pricing page ;-)

The S3 integration looks interesting. Do you have GPUs though? I think that's the main appeal of colab and I didn't see it immediately on your site
