How Much Does Running 500 Agent Sandboxes a Day Actually Cost
Hidden billing variables like session duration and idle time matter far more than headline rates.

Hidden billing variables like session duration and idle time matter far more than headline rates.
Sandbox lock-in compounds invisibly through isolation, state formats, and orchestration layers.
Persistence means three separate things, and few platforms deliver all three.
Compares how sandbox providers handle snapshot, fork, and pause.
Filesystem scoping and quotas matter more than compute isolation for bulk-file agents.
Models improve faster than sandboxes can adapt to contain them.
Network egress controls are the lock that actually stops stolen data from escaping.
AI agents need isolation criteria tailored to untrusted, autonomous code execution.
Models now sustain fourteen-hour tasks, but single-shot sandboxes weren't built for that.
What Modal Sandboxes are, how they isolate AI-generated code, what they keep between runs, how egress is locked down and how they bill.
