Lightning AI is a powerful platform designed to streamline AI development for teams, eliminating cloud-related challenges. With the ability to build foundation models using your own data on your preferred cloud, Lightning AI simplifies the AI development process. Train large language models (LLMs) with fault-tolerance and diffusion models at scale, ensuring efficient and accurate training. The deployment process is equally seamless, enabling high availability and scalable models. The platform leverages PyTorch Lightning, a fast and minimal library for training and deploying PyTorch models, including LLMs and transformers. Lightning Fabric allows teams to scale foundation models with expert-level control, while TorchMetrics provides easy-to-use PyTorch metrics optimized for scale. Lightning Apps facilitate the deployment and shipment of full-stack AI products, enabling the deployment of auto-scaling stable diffusion servers and more.
