Google open-sources AX, an agent runtime built to run billions of agent jobs on one cluster

Google open-sourced AX, an agent infrastructure designed to run billions of agent jobs on a single server cluster, per its README.
Key design points:
- Hard resource isolation: every agent runs in a sealed sandbox with strict limits on memory and compute, preventing runaway loops from piling up bills from paid model calls.
- Pre-loading: each agent's code folders and tools are loaded before startup, so nothing boots cold.
- Network lockdown: internet access is cut off except for explicitly approved domains.
- Pause/resume: agents can be frozen and restored later at the exact same execution step.
- Jobs are described declaratively in a single short text file.
The framework targets the operational reality that agents remember state, execute unreviewed code, and autonomously make repeated paid API calls — AX is Google's answer to running that safely at massive scale.
