Perplexity Details SPACE Session Mechanism
perplexity_ai · x · 2026-07-16
Perplexity further explained how SPACE works: each task receives a disposable Firecracker microVM, which is destroyed once the task finishes.
To support long-running tasks, the system uses rolling snapshots to save live memory and file states, allowing a single session to be paused, resumed, or even branched across different sandboxes.
