There are several 'web3' projects in this space, vast.ai, already mentioned, is focused on renting out GPU's from servers hosted pretty much anywhere. For low cost server hosting and egress bandwidth, Threefold (https://www.threefold.io/build/ https://www.threefold.io/build/) and Akash are two new startup web3 ecosystems looking to radically bring down the costs of cloud compute, storage, and bandwidth with GPU support on both of their roadmaps. Still very early, but at 80-95% raw cloud cost savings even beating out Hetzner/DO, its an interesting niche of token incentivized physical infrastructure networks (called TIPIN for short).
