Researchers outline agent orchestration patterns

Agent orchestration decides which agent or model handles each step of a task, with two dominant patterns: workflow orchestration and autonomous orchestration. Workflow orchestration uses a deterministic graph of agents, while autonomous orchestration uses a supervisor LLM to delegate to sub-agents. The choice between the two patterns depends on the task space, with workflow orchestration suitable for enumerable task spaces and autonomous orchestration suitable for open task spaces. Researchers also discuss common issues with agent orchestration, such as compounding errors and context fragmentation. The article provides guidance on how to implement agent orchestration, including the use of supervisor agents and sub-agent descriptions.
