We are well-suited for all flavors of AI work, but our comparative advantages shine most for:
  • Long-running or long-horizon agents
  • Background agents running autonomously for minutes, hours, or days… or longer!
  • Any token-hungry workload that does not require an ASAP response
  • Any task where thoroughness is more important than speed

The Sail Stack

Inference

Tokens at extreme scale and efficiency. We have OpenAI and Anthropic-compatible APIs for the best open source models.

Sail inference enables your agents to tackle bigger tasks by eliminating typical cost and throughput-related constraints.

Sailbox

The only sandbox in the world that’s purpose-built for long-horizon agents. Sailboxes are persistent, can run indefinitely, and are only billed for actual CPU, memory, and disk usage while running. You never pay for idle time.

This makes the Sailbox the most ergonomic and cost-efficient computer for agents.

Unleash the tokens

More agents thinking longer and harder, with space to act and explore, can do incredible things.
  • Detailuses Sail inference to deeply scan codebases for their most consequential yet hard-to-catch bugs
  • Jack & Jillruns large scale deep research with Sail inference, matching job seekers’ resumes with job descriptions from thousands of employers
  • We won Browsecomp-Plus, the AI deep research benchmark, with Sail inference
  • We built Redis in Rustwith a swarm of 4 long-horizon coding agents running on Sailboxes with Sail inference over a 27-hour, uninterrupted period
