​
Usage

Saves your workspace to cloud, then stops the instance and releases the GPU.

Arguments

​
Confirmation polling

By default, cassian down waits up to 30 seconds to confirm the instance actually stopped before returning. This makes it reliable in scripts. Use --force to skip waiting:
Useful in CI pipelines or cleanup scripts where you don’t need to block on confirmation.

​
What gets saved

  • Everything in /workspace (code, scripts, outputs)
  • Folders listed under workspace.no_sync
Not saved: pip packages, installed system packages, anything in workspace.exclude.

​
Data safety

Your workspace is saved before the container stops. If the save fails, the instance stays running and you get an error rather than losing data.

​
Billing

Billing stops as soon as the instance stops. You are not charged while the instance is off.
