Pros
- +Durable execution ensures agents automatically resume from exactly where they left off after failures or interruptions
- +Comprehensive memory system with both short-term working memory for ongoing reasoning and long-term persistent memory across sessions
- +Seamless human-in-the-loop capabilities allow for inspection and modification of agent state at any point during execution
- +跨模型兼容性强，支持 OpenAI、Ollama、vLLM 等主流 LLM 平台，代码无需修改即可切换模型
- +在生成过程中直接保证结构正确性，彻底避免了传统解析方法的错误和异常
- +集成简单，仅需一行代码即可实现结构化输出，大幅降低开发复杂度
Cons
- -Low-level framework requires more technical expertise and setup compared to high-level agent builders
- -Graph-based agent design paradigm may have a steeper learning curve for developers new to agent orchestration
- -Production deployment complexity may be overkill for simple chatbot or single-turn use cases
- -可能会限制模型的创造性输出，严格的结构约束可能影响某些开放性任务的表现
- -对于复杂嵌套结构的性能影响尚不明确，可能需要额外的计算开销
- -文档中提到的高级功能(如自定义语法、FHIR 等)似乎需要企业合作才能获得
Use Cases
- •Long-running autonomous agents that need to persist through system failures and operate over days or weeks
- •Complex multi-step workflows requiring human oversight, approval, or intervention at specific decision points
- •Stateful agents that must maintain context and memory across multiple sessions and interactions
- •电商产品分类系统，确保所有产品信息都符合预定义的类别结构和字段要求
- •客户服务工单分类，将用户反馈自动归类到准确的问题类型和优先级别
- •文档解析和数据提取，从非结构化文本中提取特定格式的结构化数据用于后续处理
