Perplexity open-sources SPACE, its agent code execution platform
The interesting part is the state machine: Pause keeps memory resident for fast recovery, Suspend snapshots VM memory plus filesystem for true persistence, with idle sandboxes auto-suspending after 6 hours. Engineers building agent sandboxes or code-interpreter features can study how warm pools and btrfs snapshots attack cold-start latency, a problem most teams still solve ad hoc. Management and attachment tokens being non-interchangeable is a useful security boundary pattern to copy.
