0G (Zero Gravity) is the first decentralized AI operating system built to power on-chain AI apps and chains. It manages compute, storage, data, and models with high efficiency, offering the fastest and most scalable data availability layer, low-cost decentralized storage, and flexible tools for AI inference and fine-tuning. 0G solves the cost and performance issues that once kept AI apps off-chain, finally making powerful on-chain AI possible.
