- What happened
- Google released Ray AI libraries optimized for TPU: Ray Serve for multi-host model serving, Ray Data with iter_jax_batches for efficient batching, and JaxTrainer for distributed JAX training.
- Why it matters
- Engineers deploying large language models or training jobs on Google Cloud TPUs who want production-grade serving, data pipelines, and training with automatic slice placement handling.
- Watch out
- Multi-host models must declare topology field in config; omitting it causes workers to scatter across slices, hanging jobs silently. JAX imports must occur inside worker functions, not at module scope.
