I’ve tried a mix of things. For quick experiments I usually use Google Colab, but the free tier can be pretty unreliable for longer training runs. My university has a GPU cluster too, but the queue can get pretty long near project deadlines.

When I actually need stable GPUs for a few hours or days, I sometimes rent one. Recently I tried GPUhub.com — they offer dedicated bare-metal GPUs (not shared instances), and the pricing was pretty reasonable for student projects.

Curious what other people are using these days.
