Learn JAX with Real Code Examples
Updated Nov 24, 2025
Performance Notes
JIT-compiled functions are orders of magnitude faster than pure Python
Vectorization with `vmap` eliminates explicit Python loops
Parallelization with `pmap` scales efficiently across devices
Avoid frequent device-host memory transfers for efficiency
Profiling with `jax.profiler` helps identify bottlenecks
Security Notes
Ensure data privacy before sending to GPU/TPU
Avoid using untrusted code in JIT-compiled functions
Validate inputs for scientific simulations to prevent invalid states
Follow secure ML pipeline best practices
Encrypt sensitive datasets if using cloud TPUs
Monitoring Analytics
Log training and simulation metrics
Monitor computation performance with profiling tools
Track device utilization for GPU/TPU
Visualize loss and accuracy curves
Audit function outputs for correctness
Code Quality
Use functional, side-effect-free functions
Document all transformation pipelines
Test gradients and compiled functions
Version scripts and parameters
Ensure reproducibility with PRNG keys
