Lightning AI

Lightning AI is a cloud workspace from the creators of PyTorch Lightning. You get browser-based studios backed by CPUs or GPUs, where you can code, train models, run notebooks and deploy endpoints without managing servers.

Studios behave like a persistent cloud computer that you can stop and start, so environments and files survive between sessions. Switching from a cheap CPU to a big GPU takes a few clicks.

It appeals to researchers and small teams who want a smoother experience than a raw cloud VM. Costs follow GPU hours, so remember to stop machines you are not using.
