## What it is
Agent Substrate is a Kubernetes-based control plane for running large fleets of stateful agent sandboxes at high density. It multiplexes many idle actors onto a small pool of workers with sub-second suspend/resume, supporting microVM and gVisor sandbox technologies.

## Use cases
- run thousands of AI agent sandboxes on a small Kubernetes cluster
- suspend and resume stateful agents in under a second
- oversubscribe idle agents onto shared worker pods
- manage microVM and gVisor sandboxes with one lifecycle API
- build infrastructure for RL loops spanning agents, inference, and training
- route incoming traffic to live agent instances

## When to choose
- you need to deploy stateful agents at scale with high density
- you want sub-second agent resume/suspend on Kubernetes
- you need consistent sandbox lifecycle across microVMs and gVisor
- you run RL workloads mixing agentic, inference, and training cycles

## When to avoid
- you want an SDK or framework for building agent logic
- you have a small number of always-active workloads with no need for multiplexing
- you are not running on Kubernetes
