Where Agents WorkA real machine for every agent.

Sandboxes that boot in under a second, fork mid-task, and keep their state when the machine goes away — built for teams of humans and agents working together.

// 01 · How agents run

Boot. Fork. Connect.

Agents don't run once — they loop, branch, and retry. AGX makes each of those moves a primitive of the machine itself.

01Boot

Every agent gets a real microVM with kernel-level isolation — provisioned over plain SSH, ready before the model finishes its first thought.ready in 0.74s

02Fork

Sub-agents branch from a running sandbox in milliseconds — parallel attempts, instant retries, resume from any snapshot.fork in 7ms

03Connect

Critical state lives outside the sandbox and outlives it. Agents discover each other on the mesh and reach the resources they need.stateful · mesh-discoverable

One SSH command away

No SDK required, no custom client — if it can ssh, it can work on AGX. Humans and agents use the same door.

// 03 · Performance

Agentic performance at scale

Agents loop, branch, and retry — often spinning up a sub-agent and a fresh sandbox at every step. Substrate boots and forks sandboxes up to 10× faster than Firecracker, so a fleet never waits on cold starts.
