Multi-agent LLM orchestration incurs significant cost and latency, study finds

By PulseAugur Editorial · [1 sources] ·

A study comparing two approaches to LLM agent execution found that orchestrating multiple agents, while maintaining identical accuracy, significantly increased costs and latency. The research evaluated an "Inline Arm" where a single agent handled all tasks versus an "Orchestrated Arm" that delegated work to multiple child agents. Across 20 programming tasks, the orchestrated approach resulted in 3.47x to 4.38x more billed tokens and was 2.41x to 7.76x slower, demonstrating a substantial "fork tax" associated with multi-agent coordination. AI

IMPACT Highlights the significant overhead of multi-agent coordination, suggesting single-agent architectures may be more cost-effective for certain tasks.
