About Lightning AI

Lightning AI is a unified platform for AI development that enables teams to prototype, train, deploy, and serve models with minimal setup. It integrates the PyTorch Lightning ecosystem (Fabric, TorchMetrics, LitServe, LitModels, Lightning Thunder) to provide browser-based collaboration, autoscaling cloud deployment, and production-grade serving for models, agents, and retrieval-augmented pipelines. The platform emphasizes developer productivity (zero local setup, reusable templates), scalable inference (multi-GPU batching, streaming, multi-model support), and flexible hosting (self-host or deploy to Lightning AI cloud with built-in autoscaling and access controls).
