io.net (operated by IO Research) builds the 'Internet of GPUs,' a decentralized compute network on Solana that pools hundreds of thousands of GPUs from independent suppliers into a single, on-demand cloud. Engineers can spin up GPU clusters for model training, fine-tuning, and inference at a fraction of the cost of centralized hyperscalers. Suppliers stake and earn the native IO token for contributing hardware, while workloads are orchestrated across the network using a Ray-based clustering layer. The platform targets the AI compute shortage by making distributed, geographically dispersed GPUs usable as a coherent cluster, and has connected over 100,000 GPUs since launch. io.net positions itself at the intersection of crypto incentives and AI infrastructure, with token-based settlement and a marketplace for compute.
