What is Sail Research?
Sail Research operates at the intersection of high-performance computing and artificial intelligence, providing the foundational infrastructure required for autonomous, long-horizon AI agents. The company's platform is bifurcated into two primary technological pillars: a re-engineered inference stack that achieves significant cost reductions per token, and Sailboxes, a proprietary stateful sandbox environment designed for extended, multi-day execution. This architecture addresses the primary bottlenecks currently hindering the deployment of ambitious, long-running AI agents in enterprise settings. By optimizing for both efficiency and duration, Sail Research enables developers to move beyond short-lived tasks toward more complex, goal-oriented agentic systems.
