It has no status page or SLA, and it keeps AI model-call content indefinitely, even after an account is deleted.\n\n**Modal Sandboxes.** GPU sandboxes at the same per-second rates as the rest of Modal. No REST API, and the JavaScript and Go SDKs are beta.\n\n## Before you call either\n\n### Maritime\n\n1. Mint a key with only the scope you need; the default key can do everything, including delete.\n2. Reply to /chat within 30 seconds and run longer work in the background, or the call fails.\n3. Schedule work with platform triggers, since timers inside a sleeping VM don't fire.\n4. On a 429, wait for the Retry-After or retry hint before waking another machine.\n5. Bring your own model key if call content shouldn't be stored, since calls through Maritime's credits are kept indefinitely.\n\n### Modal Sandboxes\n\n1. Pass `timeout=` when you create a sandbox. The default lifetime is 5 minutes\n2. Set `block_network=True` or an `outbound_cidr_allowlist` for untrusted code\n3. Give a sandbox a `name` so a retried create raises `AlreadyExistsError` instead of starting a second one\n4. Snapshot the filesystem before the 24-hour limit and start a fresh sandbox from it\n5. Catch `ResourceExhaustedError` from `Sandbox.create()` on SDK 1.6.0 and later, since create now waits until scheduled\n\n## Questions\n\n### Which is better for AI agents, Maritime or Modal Sandboxes?\n\nMaritime and Modal Sandboxes score within a point of each other on agent readiness, 66.5 (B) and 65.9 (B). Modal Sandboxes leads on reliability, security \u0026 auth, maintenance \u0026 community and transparency \u0026 trust.\n\n### Can an agent call Maritime and Modal Sandboxes without installing anything?\n\nMaritime has a hosted endpoint at https://mcp.maritime.sh/mcp.
