Perplexity Develops SPACE for AI Agent Sandbox Management

@AravSrinivas· July 15, 2026 View original

Summary

Perplexity has developed SPACE, its own sandbox lifecycle management platform, to handle all production traffic for Perplexity Computer. This internal solution has resulted in 5x faster tail latency and significant cost savings compared to external providers, while also enhancing security for agent runtimes.

Perplexity has announced the creation of SPACE, an in-house platform designed for sandbox lifecycle management. This platform is now exclusively responsible for serving all production traffic for their AI agent product, Perplexity Computer. The transition to SPACE, from previously relying on external sandbox providers, has yielded substantial operational improvements. Notably, Perplexity reports a five-fold reduction in tail latency, leading to a much faster user experience. Furthermore, SPACE offers considerable cost advantages, being five times cheaper than previous solutions like Vercel, translating into millions of dollars in annual savings. Beyond performance and cost, the platform also enhances security by isolating long-running agent sessions and ensuring that sensitive credentials are never directly stored within the runtime environments.

Why it matters

For companies operating AI agents at scale, managing infrastructure efficiently and securely is paramount. Perplexity's success with an in-house solution demonstrates the potential for significant cost savings, performance improvements, and enhanced security by taking control of critical infrastructure components.

How to implement this in your domain

  1. 1Evaluate the cost-effectiveness and performance of current external sandbox or compute providers for AI agent workloads.
  2. 2Assess the security implications of running AI agents on third-party infrastructure, especially regarding credential management.
  3. 3Consider developing custom infrastructure solutions for critical AI agent deployments if scale and specific requirements warrant it.
  4. 4Benchmark internal solutions against external providers to quantify potential gains in latency, cost, and security.
