Basically, a cloud compute service for AI development. You run your code on their hardware.
**Why Paperspace?**
Paperspace makes it easy to run resource-intensive, long-running AI calculations. Paperspace is convenient, free, and you probably don't have a computer good enough to run the AI.
You'll run your code on their powerful GPUs which is much faster and easier than locally on your computer.
**Do I have to pay?**
Only if you feel limited by their free tier. You should have everything you need to generate ~~porn~~ really neat images.
**Why not Google Colab?**
Google Colab is an alternative, but their free tier is more restrictive than Paperspace's and has less powerful hardware.
