Introducing Sailboxes: Persistent Sandboxes for Long-Horizon Cloud Agents — from the Sail Research blog on efficient AI inference.
Building long-horizon agents that do meaningful work has never been easier. Or more visible.
Sail Research raised $80M in seed and Series A funding — seed led by Sequoia Capital, Series A led by Kleiner Perkins — to build the most efficient inference and long-running sandbox infrastructure for long-horizon AI agents.
