Lumino is a machine learning model training platform that can reduce costs by 50-70%. Users can train machine learning models on its extensive network of computing resources, and they can also supply their own computing resources. The platform significantly lowers costs by cutting out middlemen (such as AWS, GCP, and Azure) and connecting directly with computing resource providers. All models and training datasets are traceable to cryptographically verified evidence, ensuring complete accountability. Additionally, Lumino's decentralized and permissionless network structure prevents the abuse of power by centralized cloud platforms and authoritarian states.
