Key Info

Perplexity described how it built the filesystem behind Perplexity Projects as a Git forge for agents, where each agent works in its own sandbox and commits to a shared repository that people and other agents can build on across sessions.

Highlights

  • Each agent runs in its own ephemeral sandbox rather than a single long-lived sandbox per project, avoiding provisioning for peak load and months of uptime.
  • Repositories live on S3-backed storage, so a crash loses only unsubmitted work.
  • Because each sandbox holds a real checkout, agents search with grep and standard file tools instead of broad semantic searches.
  • On an internal benchmark of 150 financial-document questions, this approach reached 0.627 answer accuracy versus about 0.37 for semantic search.
