Agent Orchestrators Are Bad (12gramsofcarbon.com)

A recent critique of agent orchestrators in the AI/ML community challenges the growing hype surrounding these systems, arguing that they often yield subpar outcomes despite higher costs. The article posits that while agent orchestrators can theoretically manage multiple AI agents simultaneously, they sacrifice efficiency and accuracy due to inevitable information loss during inter-agent communication. This is particularly concerning for tasks that require high contextual awareness, where the degradation of input across iterations—evidenced by a loss of critical information—can result in significant failures during sequential workflows such as software development. Technical insights highlight that agent orchestrators operate within the confines of an LLM's fixed context window, which limits the data they can process at one time. As these models lose focus and begin to hallucinate during extended tasks, the effectiveness of using multiple subagents diminishes further. Studies cited in the article indicate that multi-agent systems can amplify errors and degrade performance in sequential reasoning tasks by a staggering 39-70%. The author contends that while agent orchestrators may excel in tasks suited for parallel processing, their practical utility in complex workflows, such as programming, remains questionable.
