### TL;DR
Sprites are persistent, hardware-isolated Linux environments designed for running arbitrary code with stateful checkpoint and restore capabilities. They function as dedicated microVMs that hibernate when idle and wake automatically, making them ideal for AI agents, development environments, and secure code execution.
