Perplexity AI

TL;DR

SPACE is a new sandbox platform designed for advanced AI agentic systems, developed by Perplexity.
It aims to provide high security, functionality, and efficiency, overcoming previous tradeoffs.
SPACE uses ephemeral sandboxes that are destroyed after task completion and session management for long-horizon work.
The platform separates concerns across dedicated services (Network Gateway, Space Daemon, File Service) for enhanced security.
SPACE features three security layers: Control Plane, Node-level Services, and In-sandbox Firecracker microVMs.
Credentials are not exposed within the sandbox; they are provided only when needed.
SPACE offers features like pause/resume, session forking, per-session credential isolation, and multi-backend orchestration.
It supports rolling snapshots that capture live memory and files, allowing for task resumption even after a week.
Enterprise customers can use their own encryption keys, and the system can operate on-prem and offline.
SPACE has been used internally by Perplexity for two months, supporting millions of sandbox creations.
Early tests show performance improvements on NVIDIA Vera CPU for Computer-style workflows.
