Ever thought about running ML models straight from your browser? No servers, no latency headaches—just pure computational power at your fingertips. The shift toward on-device model training and deployment is reshaping how we think about decentralized applications. Why wait for backend responses when your browser can handle it? This approach cuts infrastructure costs, enhances privacy, and opens new possibilities for Web3 applications that demand real-time intelligence without central authority. The tech stack is getting there—WebAssembly, Web GPU, and optimized frameworks are making this less sci-fi and more reality.
