PyTorch Lightning: Simplifying Deep Learning for Developers and Researchers

PyTorch Lightning is a powerful, user-friendly framework designed to streamline the development and training of machine learning models using PyTorch. Built for both beginners and advanced practitioners, it enables efficient training with support for complex architectures like diffusion models, recurrent neural networks, object detection, and text classification. With features such as multi-GPU and mixed-precision training, model checkpointing, learning rate finders, schedulers, and hyperparameter sweeps, it accelerates deep learning workflows while minimizing boilerplate code. The platform seamlessly integrates with LitServe for API deployment and supports RAG pipelines, agentic workflows, and secure data processing. Trusted by over 300,000 developers and leading AI companies, PyTorch Lightning offers a cloud workspace with zero setup and frictionless deployment on cloud GPUs—ideal for academic use, startups, and enterprise teams. Part of the broader Lightning AI ecosystem, which includes tools like LitGPT, TorchMetrics, Fabric, and Thunder, it empowers users to focus on innovation, not infrastructure.
