Google Cloud says GKE Agent Sandbox lifts agent density from 61 to 274 per node

Google Cloud says its GKE Agent Sandbox can pack far more AI agents onto the same node by freezing idle workloads and freeing resources.
- On a fixed n2-standard-48 machine, the baseline setup ran 61 agents.
- With GKE Agent Sandbox, that rose to 88 agents.
- A latency-sensitive configuration reached 141 agents.
- A cost-optimized configuration reached 274 agents, or 5.7 agents per CPU.
The blog frames agent workloads as bursty and wasteful when treated like static compute. Its recommendation is to build orchestration in from the start, so idle agents can be suspended and resumed instead of occupying CPU and memory continuously.
