> Truly intelligent AI agents need to run arbitrary code, but you won't get there with standard infra_

Traditional sandboxes expire in hours to days, forcing you to build complex orchestration around to maintain state, or accept a slow, cold start every session.

Plus, when agent logic runs separately from your sandbox provider, network latency gets compounded: chained executions are even slower, and teams trade performance for operational overhead.
