Run Claude Agent Swarms Without Burning Your Limit
Dynamic workflows run many Claude agents at once, and every one draws on your plan's limit. Three controls that keep the swarm cheap, the one new setting to test first, and what a smaller model is worse at
A dynamic workflow runs dozens of Claude agents from one script. Anthropic's docs say those runs count toward your plan's usage and rate limits, and an agent with no other model assigned runs on your session's model.
Here are the three controls, the one new setting to test before you trust it, and the catches.
What a swarm costs you
- Every workflow agent draws on the same plan limit as your normal chat.
- With nothing else set, each agent runs on your session's model, so an Opus session means an Opus swarm.
- Claude Code warns you ('Large workflow') when a run schedules more than 25 agents or projects over 1.5 million tokens. It is a warning only; it doesn't stop the run.
