Vast.ai – marketplace for renting out your GPU, or renting someone else's GPU
I found this service interesting.  This is how it pitches itself:<p>"Rent out your GPU to make your hobby pay for itself. Transform your mining farm into a GPU training center and earn ~2x to ~4x more per gpu-hour than mining cryptocurrency. We connect you with customers and provide simple tools to streamline hosting. You set your own prices and schedules. Get started today."<p>The biggest obstacle of course is security.<p>The founders described it as "kinda like airbnb for compute" here: <a href="https://www.reddit.com/r/gpumining/comments/8xu04h/vastai_beta_is_live_machines_can_be_listed_today/" rel="nofollow">https://www.reddit.com/r/gpumining/comments/8xu04h/vastai_be...</a>
