UnverifiedAgent code typically contains just one line, agent.run(query); which tools to call, what internal analysis to perform, or whether to keep thinking is left to the model itself, resulting in non-deterministic execution paths.77% similarUnverifiedA Workflow's control flow is predetermined by code with a fixed execution path, whereas an Agent's every step is autonomously decided by an LLM, giving it dynamic planning capability77% similarVerifiedIn workflow-type agents, the execution path is pre-designed by humans, whereas an Agent Loop lets the model autonomously plan what to do next.76% similarVerified工作流（Workflow）是确定性的，预先定义节点顺序；Agent模式是自主性的，由大模型自主决定调用工具和步骤76% similarUnverifiedEvery task should start with the workflow pattern, and only migrate to the agent pattern when the steps truly cannot be fixed.76% similar
