Kind: release · Impact: medium

## In brief

- Google announced TPU Sync, an open-source system for moving KV cache and model weights on TPU, alongside its eighth-generation TPU announcement.
- The system targets data movement between memory types, which becomes a bottleneck as context windows grow.
- The New Stack reports Google claims inference latency cut by over 90%, with a caveat it does not detail in the available text.

## Why it matters

Teams running disaggregated serving, long-context agents, or continuous RL on TPUs could see lower inference latency if the claimed gains hold up.
