Google Open-Sources TPU Sync Library

Google Cloud open-sources TPU Sync, a C++ library for moving KV cache and model weights on TPUs. The project targets long-context and reinforcement learning workloads, reporting 60% TTFT reduction for Qwen3 235B and 90% for a 480B model. Developers receive Python wheels for JAX and PyTorch, with APIs for KV cache management and weight synchronization.
