Framework & Tool
PyTorch
Meta's dynamic deep-learning framework, dominant in research and increasingly in production.
Definition
PyTorch's eager execution model, Pythonic API and rich ecosystem (Lightning, Hugging Face, vLLM) made it the default deep-learning framework. PyTorch 2.x added torch.compile for AOT compilation, closing the historic performance gap with TensorFlow/JAX.
