What happened
AX is Google's open-source agentic orchestrator that runs AI agent tasks as declarative Kubernetes-style YAML manifests. It provides four primitives—Task (sandboxed execution with CPU/memory limits), Workspace (auto-wiring Git repos, MCP servers, and skills), Gateway (network allowlist policies), and Model (centralized model/key config)—built on a custom 'Agent Substrate' runtime that claims billions of concurrent actor sessions per cluster with sub-second checkpoint/resume.
Why it matters
If you're building agent infrastructure, AX gives you a concrete declarative pattern to steal: sandbox per task, explicit network fencing, workspace-as-code, and centralized model config rotation. The sub-second suspend/resume of idle agents waiting on model/tool responses is the detail worth evaluating—most current agent runners either hold resources or pay cold-start costs. Check the GitHub repo to see if the 'Agent Substrate' runtime is actually open or just the CLI layer.
Discussion angle
Compare AX's declarative YAML approach to existing agent runners (LangGraph, CrewAI, AutoGen)—is Kubernetes-for-agents the right abstraction, or is it over-engineered for teams running dozens rather than billions of agents?
