One objective
A Run Group holds the main execution and any delegated or parallel work for one request.
Runs
Agent execution
Runs
Follow agent work from request to result, including progress, outputs, approvals, traces, and usage.
How work is organized
Swarm separates the overall objective from each execution attempt, making parallel work and retries easier to follow.
Each attempt
A Run records one execution attempt with its own status, timeline, model usage, and outputs.
Delegated work
A subrun handles a focused piece of work when an agent delegates or works in parallel.
What you can inspect
The result is not a black box. Swarm keeps progress, evidence, and available controls attached to the work that produced them.
Progress
See which steps are complete, active, waiting, or unsuccessful.
Evidence
Open artifacts, action receipts, evaluations, token usage, and traces linked to the Run.
Control
Pause, resume, cancel, approve, or retry when those actions are available.
