Perplexity Launches SPACE: Secure Sandbox Runtime for Long-Running AI Agents

What's new

• SPACE runtime: Sandboxed Platform for Agentic Code Execution — isolated VM environment for each agent session, built on AWS Firecracker microVM
• 60ms median latency: vs. 185ms before (89ms P90 vs. 447ms before — ~5x speedup)
• Pause, resume, and branch: sessions can be paused, resumed, and branched; credentials managed separately
• Long-running task support: agents can work for hours, days, or months in the same sandbox
• Brain — self-improving memory: new feature learning from every task, building a private context graph — improved answer correctness by 25% in tests

Why it's worth attention

SPACE solves a key problem in production AI agent deployment: security and isolation without performance loss. It powers 100% of Computer sessions and has handled millions of sandbox creations.

How to try it

Perplexity Computer (available to Pro subscribers) runs automatically on SPACE.
