Single-agent advantage
Fewer calls, simpler state, clearer accountability and easier debugging.

Single Agent vs Multi-Agent Cost: When Coordination Pays
Compare a single agent with a multi-agent system using model calls, repeated context, handoffs, retries, review and coordination tax.
Direct answer
Use one agent by default. Add specialist agents only when the measured increase in accepted outcomes, quality or cycle time exceeds the coordination tax created by extra model calls, repeated context, handoffs, tracing and failure recovery.

Verified facts
Multi-agent advantage
Useful specialisation, parallel work and independent checking when the task genuinely benefits.
Coordination tax
The additional landed cost of the multi-agent design compared with an equivalent single-agent design.
Break-even test
The multi-agent design must improve acceptance enough to match or beat the single-agent cost per accepted task.
Costs to include
- •Model calls per role
- •Repeated context and memory
- •Handoffs and supervisor cycles
- •Parallel branches and retries
- •Tracing, infrastructure and human escalation
Choose this way
- •Choose one agent for bounded workflows with a clear tool set.
- •Choose multi-agent only for demonstrated specialist or independent-review value.
- •Use the calculator to measure the break-even acceptance-rate improvement.
Avoid these mistakes
- •Do not create one agent per organisational job title by default.
- •Do not use an LLM agent where deterministic code is enough.
- •Do not accept extra orchestration without measurable output improvement.
