When to Choose Each Option
Clear guidance based on your specific situation and needs.
Our Recommendation
There's no universal winner — the axis is capability ceiling versus operational control. Recursive sub-agents are the stronger choice for the hardest, most open-ended work, where a worker genuinely needs to spawn its own helpers and depth-of-reasoning beats breadth. But they inherit context at every level, compound the ~15x token multiplier that multi-agent systems already carry, and turn execution into an opaque chain that is hard to debug and prone to runaway loops without strict boundaries. Flat sub-agent teams remain the production default for good reason: predictable cost, clear observability, easy human intervention, and a hierarchy that is hard to break. The pragmatic pattern Context Studios favors is to keep flat teams as the default, route each node to the cheapest capable model, and reach for recursion only on the few tasks whose quality ceiling — Anthropic measured 90.2% better results from multi-agent over single-agent — justifies the cost and the loss of visibility.
- Choose Recursive Sub-Agents when...
- Your problems are deep and open-ended, where a worker genuinely needs to spin up its own helpers mid-task
- You are tackling the hardest multi-stage refactors or research where depth-of-reasoning beats breadth
- Answer quality dominates the decision and you can afford the 15x-style token multiplier
- You have hard depth limits, token budgets and termination boundaries in place to contain runaway recursion
- Choose Flat Sub-Agent Teams when...
- You run production workflows where predictable cost and latency matter most
- You need clear observability and easy human intervention points at every step
- Your tasks parallelize naturally into independent, well-scoped subtasks
- You want the battle-tested default that is hard to break and easy to debug
