> As an aside, if you do get a V100, Colab Pro is by-far the cheapest way to train an AI model.

But others should be aware that you get what you pay for. Google still rate limited me when I used Colab Pro, and I ran into a myriad of other small problems. If that's all one is willing to spend to play with AI, 100% go for it. It's a great place to start. But if you're at all serious and can afford it, I think a local machine with a modest GPU is worth every penny.
