Nous Psyche is a decentralized, cooperative training network for generative AI, developed by Nous Research and built on the Solana blockchain. It leverages a novel networking stack called Nous DisTrO, which significantly reduces inter-GPU communication during pretraining, enabling efficient coordination of heterogeneous hardware for model training. By utilizing idle GPUs globally, Psyche democratizes the development of superintelligence, making AI training more accessible and transparent. Psyche addresses the centralization of AI development by providing an open infrastructure that empowers individuals and organizations to participate in the creation of superintelligent systems. By harnessing underutilized computational resources, it offers a cost-effective and scalable solution for AI training, fostering innovation and reducing dependency on large tech entities. This approach not only accelerates AI advancements but also ensures that the benefits of superintelligence are accessible to a broader community.
