The author argues that the common multi-agent system architecture, which relies on a router-orchestrator to delegate tasks to specialized agents, is becoming outdated. This approach was effective when language models struggled with long contexts and complex decision-making. However, recent advancements in models from companies like OpenAI and Microsoft have improved their ability to handle long instructions and select from numerous tools. The author suggests that starting with a single agent and adding tools before multiple agents is now the recommended approach, as multi-agent handoffs can lead to information loss, conflicting decisions, and debugging difficulties.
