simonguozirui · x · 2026-07-15
Sail Research has launched Sailboxes, claiming it to be the first cloud environment specifically designed for long-horizon AI agents.
- Provides full machine environments with persistent state, supporting automatic hibernation, tailored for agents built to "exist long-term."
- Pricing starts at $0.015 / active vCPU-hour. The team claims it is 70%+ cheaper than alternatives, charging only for actual active usage.
- Built on a new architecture that enables live migration of virtual machines based on real-time resource utilization.
- The team demonstrated the capability using a Minecraft server, forcing a migration every 2 minutes without players noticing.
