Deep Learning Framework Trends: PyTorch vs. JAX

Prompt

Discuss current high-level trends in deep learning frameworks. Then compare PyTorch and JAX across at least three dimensions, such as:

Programming model and NumPy affinity
Compilation and execution strategy
Accelerator portability and distributed training

Conclude with concrete scenarios where you would prefer one framework over the other.

Minimal Context

Assume the reader knows Python and array-based ML, but not the internals of each framework. Focus on how design choices affect performance, portability, and developer productivity.
