In the fast-changing world of AI and computers, there's a big problem - there aren't enough powerful GPUs (like graphics cards) available for all the cool AI projects. But here comes something called DePINs, which stands for Decentralised Physical Infrastructure Networks. These networks use regular people's GPUs and some datacenter GPUs that aren't used by the big companies like Amazon or Google. DePINs encourage people to share their GPU power and create groups of GPUs that AI developers can use. This helps solve the shortage of computing power, and it's cheaper than using big cloud services. It could change the way AI work is done and speed up the AI revolution.
