AX

We are still actively refining our core concepts, protocols, and specifications. We will likely to introduce major breaking changes prior to a stable release.

Declare an agentic task with workspaces and gateway specifications. AX sandboxes it, wires up its workspace, fences its network, and helps running it at scale.

AX is a high-throughput, declarative orchestrator to run billions of autonomous agent workloads in a cluster. It runs on top of Agent Substrate for sandboxed execution and is built to run billions of tasks per cluster. If you have used Kubernetes, ax will feel similar.

# 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   # lets you `ax ssh` into the sandbox

Then apply it, watch it come up, and look over the agent’s shoulder:

ax apply -f task.yaml
ax watch task test
ax ssh test -- ls -al /workspace

Why?

Agents are a new kind of workload. They are neither stateless microservices nor run-to-completion 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:

Everything is expressed as ax.io/v1alpha1 manifests and applied with a single command.

Quick start

1. Install the CLI

go install github.com/google/ax/cmd/ax@latest

This puts the ax binary in $(go env GOPATH)/bin. Make sure that directory is on your PATH.

2. Deploy the control plane

You need a Kubernetes cluster, ko (brew install ko), a container registry your cluster can pull from, and a reachable Agent Substrate Control API (in-cluster default: api.ate-system.svc.cluster.local:443).

make deploy AX_IMAGE_REPO=<your-registry>

This deploys Redis, then builds and deploys the control plane images with ko. Everything lands in the ax-system namespace.

3. Run your first task

ax apply -f examples/task.yaml       # Task + Workspace + Gateway + Model in one file
ax get tasks
# NAME      ATESPACE   PHASE     ACTOR           WORKER-IP    AGE
# task123   default    Running   task123         10.20.3.67   1m

ax watch task task123                # stream phase and condition changes live
ax ssh task123 -- ls -la /workspace  # poke around inside the sandbox
ax suspend task task123              # checkpoint and pause
ax resume task task123               # pick up where it left off

Want to see the whole lifecycle end to end? Run ./demo.sh. It applies a custom workspace, waits for readiness, runs commands over ax ssh, and suspends the task.

CLI usage

ax talks to the control plane over gRPC. It is deliberately kubectl-shaped: apply, get, describe, watch, delete, plus a few agent-specific verbs.

Everyday commands

# Apply anything (multi-document YAML, file or stdin)
ax apply -f examples/task.yaml

# Tasks
ax get tasks                          # list
ax get tasks -a my-atespace           # list in another atespace
ax get task task123                   # full spec + live status as YAML
ax describe task task123              # human-readable detail
ax watch task task123                 # stream status and condition transitions
ax suspend task task123               # checkpoint actor state and pause
ax resume task task123                # resume a suspended task
ax delete task task123

# Shell into the running sandbox
ax ssh task123                        # interactive shell (task needs spec.debug: true)
ax ssh task123 -- ls -la /workspace   # one-off command
ax ssh task123 -- python3 main.py

# Gateways, workspaces, models follow the same pattern
ax get gateways
# NAME              ATESPACE   LISTENERS             EGRESS-HOSTS
# default-gateway   default    8494/gRPC,8080/HTTP   *
ax describe gateway default-gateway
ax delete gateway default-gateway

ax get workspaces
# NAME                ATESPACE   GIT-REPOS   MCP-SERVERS
# default-workspace   default    1           1
ax describe workspace default-workspace
ax delete workspace default-workspace

ax get models
# NAME            ATESPACE   PROVIDER   MODEL
# default-model   default    google     gemini-3.8-flash
ax describe model default-model
ax delete model default-model

# Connection plumbing
ax ctx                                # active kube context and how ax is reaching the control plane
ax tunnel list                        # background tunnels (state lives in ~/.ax/tunnels)
ax tunnel stop
ax version

Works with kubectx

ax follows your active Kubernetes context. Switch clusters and ax resolves and tunnels to that cluster’s control plane in the background.

kubectx staging-cluster
ax get tasks

kubectx prod-cluster
ax get tasks

# Or target a context without switching
ax --context=dev-cluster get tasks
