UnverifiedOrchestration-Based Agents combine LLM reasoning capabilities with deterministic workflow logic, allowing developers to define when an Agent should make decisions versus follow a fixed process.80% similarUnverifiedAgent具备规划、工具调用、记忆与自主迭代的能力，区别于传统大语言模型的单次问答模式76% similarUnverified纯智能体（Autonomous Agent）将决策权交给大模型，工作流编排（Workflow）保留决策权在开发者手中76% similarUnverifiedAgent系统的可观测性需要处理语义层面的信息，不仅要知道调用了什么API和耗时，还需理解Agent决策原因和推理质量，因此评估引擎必须与追踪系统深度耦合75% similarUnverifiedAgent框架背后的大语言模型能力比框架本身更能决定编程任务的完成质量74% similar
