Offload the work of an LLM agent to a box in the cloud, so it doesn’t run on your laptop. This has security benefits (no access to your laptop’s files) and you can scale it up (run a lot of agents at the same time).
Then put a “sandbox” around these agents, that word has many meanings. In this case they fence the network traffic, so likely some kind of allowlist for network requests so that the agent doesn’t exfil crap to random websites. They also limit the resource limits of the sandbox, so that is beneficial to the cost of running these agents.
