Overview
Research summary
PyTorch Lightning separates model and training logic from repetitive execution infrastructure. Developers implement their model behavior in structured components while Lightning handles tasks such as accelerator placement, mixed precision and distributed training. The same repository includes Fabric for users who need more direct control over an existing PyTorch loop. These abstractions support experimentation and scaling without requiring every project to recreate the surrounding training engine. Lightning’s commercial cloud service is a separate offering from this Apache-licensed framework.
