Long-running agents become more usable when their code execution is isolated, disposable, and resumable instead of quietly accumulating access and state in one persistent environment

Perplexity has introduced SPACE, a sandboxed execution platform for agents that run over extended periods, using disposable Firecracker microVMs, snapshots, and paused-session restoration. TLDR IT surfaced the release; the durable pattern is that autonomous work needs a designed runtime boundary rather than an unrestricted machine with an ever-growing task history.
Why this matters: Useful agent autonomy depends on operational controls as much as model capability. Teams should define isolation, credential scope, network reach, retention, review points, and recovery before approving agents that can act for hours or days.
