Declare an agentic task. AX runs it at scale. AX sandboxes your task, wires up its workspace, fences its network, and helps you run billions of them per cluster. Either use a single task per agent, or compose as many as your agent needs. Get started View on GitHub Pause $ cat task.yaml apiVersion: ax.io/v1alpha1 kind: Workspace metadata: name: golang spec: git: - repo: https://github.com/golang/go.git branch: "my-fix" --- apiVersion: ax.io/v1alpha1 kind: Task metadata: name: test spec: workspaces: - name: golang goal: "Ensure that Go tool chain is available and is built from source" debug: true $ ax apply -f task.yaml workspace.ax.io/golang created task.ax.io/test created $ ax watch task test Watching task default/test...

They are neither microservices nor batch jobs. They accumulate state, need strict isolation, call out to model APIs and tool servers, and can burn money in a loop if nobody is watching. AX gives you four small primitives that handle all of that declaratively. Task Isolated execution Run untrusted agent code in a sandbox with CPU and memory limits. Cheap to create, suspend, and throw away. Workspace Easy workspace setup List the Git repos, MCP servers, and skills an agent needs, or just describe the goal. AX sets it all up in every sandbox before the task starts. Gateway Network policies Define and quickly manage network policies. Lock traffic down to an explicit allowlist of hosts and ports, inject credentials to the incoming requests. Model One place for config Configure models, model parameters, and secrets in one place. Rotate a key or pin a new model version with one apply. How it works Scales up to billions of tasks. AX runs on top of Agent Substrate , a compute runtime designed from the ground up for massive density and fast stateful actor lifecycles. Billions of tasks Every task runs as a lightweight actor, allowing you to scale to billions of concurrent agent sessions per cluster without orchestrator limits. Sub-second resumption Idle agents waiting on model responses, external tool calls, or human responses are checkpointed, suspended, and brought back in under a second with zero cold-start delay. Dense multiplexing Dozens of tasks share worker resources, turning idle waiting time into spare compute capacity so you only pay when agents are actively thinking and running code. Generative platform Generative features built into the platform. AX integrates generative AI directly into the platform. For example, if you want to set up a workspace just by explaining it in plain English, the environment is prepared automatically before your task starts. task.yaml apiVersion : ax.io/v1alpha1 kind : Task metadata : name : data-analysis spec : workspaces : - name : python-env goal : "Set up a Python 3 development environment" Generative workspaces Describe what a ready environment looks like in plain English. AX hands that goal to an agent on first boot to install toolchains and verify dependencies. Run anything and everything Interactive coding agents, long-running agent servers, Jupyter notebooks, headless browser testing, and custom tool runtimes—you name it. Perfect for research Spin up massive number of reproducible sandboxes to collect trajectories, run reinforcement learning loops, and evaluate agents at scale. For builders & researchers Built to be the most friendly runtime for developers and researchers. We want to make dealing with agentic infrastructure easier so you can focus on your work. AX is designed with an uncompromising focus on ergonomics, rapid iteration, and joyful workflows for both application developers and AI researchers. We aim to keep the runtime minimal and lightweight, while tastefully adding the essential features everyone needs to build, evaluate, and scale agents. About Born from research, built for production. AX was born at Google when agentic runtime systems research met frontier compute. Over years of building and operating agentic execution engines, teams across Google recognized that agentic workloads represent an entirely new computing paradigm: stateful, bursty, long-running actors that compute intensely for a minute and then wait for model responses, tool responses, or human approval. Traditional orchestrators built for stateless microservices or predictable batch jobs become cost-prohibitive when keeping idle sandboxes running, yet lack native support for sub-second suspend and resume. Drawing on agentic runtime research from Google DeepMind alongside deep experience in large-scale isolation, resumption, and scheduling, AX is being built as an open, declarative control plane purpose-built for agent execution. It abstracts tasks, workspaces, network policies, and models into core primitives so developers and researchers can run massive fleets of agents without reinventing the underlying infrastructure. This project heavily relies on Agent Substrate but provides agentic abstractions and generative runtime components. (626 points, 285 comments on Hacker News)
