PyTorch
In plain terms
A popular, flexible deep-learning framework from Meta.
Going deeper
PyTorch offers dynamic computation graphs and a Pythonic feel that made it the favorite for research and increasingly production. It's intuitive and widely adopted.
Under the hood
Eager execution eases debugging; dominant in research, with strong deployment via TorchScript/ONNX.
Examples
Research, LLM training, computer vision, Hugging Face, prototyping.
