## The brief

Google made its reinforcement-learning version of GKE Agent Sandbox and orchestration SDK generally available. It combines prewarmed environments, image streaming and reusable pods to reduce time that training accelerators spend waiting for execution sandboxes. In Google’s tests on a fixed ten-node pool, average startup improved roughly tenfold and worst-case waits improved up to 45-fold; those figures describe the published benchmark configuration.
