## The use case: how Trajectory deploys Daytona

Trajectory uses Daytona's sandbox infrastructure in its reinforcement learning post-training pipelines, provisioning large numbers of isolated, stateful sandboxes in parallel where AI agents train on replicas of customers' tools and systems. Snapshots and a warm pool are used to pre-configure environments, and lifecycle controls tear sandboxes down automatically.

Summary written by usedby from the source page, in English. The figures are those of Daytona and Trajectory, not ours.

> Combined with Daytona’s warm pool of snapshot-based sandboxes, startup times have dropped from 30 minutes to seconds. That speed enables Trajectory to run RL training loops at the pace their pipeline demands, accelerating model iteration and increasing training throughput.

- **700k**: “700k sandboxes provisioned with Daytona”
- **15+ hours**: “15+ hours of engineering time saved monthly”

> Daytona lets us spin up environments that used to take up to 30 minutes in under five seconds. And we can do that for thousands of sandboxes at once, which is what makes efficient RL post-training possible.
