No. They can run sequentially when one step depends on another, or in parallel when work items are independent.
**Can I control how many subagents run simultaneously?**
Yes. In v1.0.66+, usage-based billing users can configure **subagent concurrency and depth limits** directly from `/settings`. The concurrency limit controls how many subagents run in parallel; the depth limit controls how many levels deep delegation can chain (preventing runaway recursive subagent trees). These settings give you predictable control over resource consumption during complex orchestrated tasks.
## Next steps
- Read [Building Custom Agents](../building-custom-agents/) to design coordinator and worker agents.
