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
- +显著降低微调成本：只需训练0.1-1%的参数，大幅减少计算和存储需求
- +与主流库深度集成：无缝支持Transformers、Diffusers、Accelerate等生态
- +性能卓越：在多个基准测试中达到与全量微调相当的效果
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
- -学习曲线较陡：需要理解不同PEFT方法的原理和适用场景
- -方法选择复杂：面对多种PEFT技术（LoRA、AdaLoRA、IA3等）需要根据任务特点选择
- -依赖特定框架：主要针对HuggingFace生态优化，其他框架支持有限
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
- •大模型个性化定制：在资源受限环境下为特定领域或任务微调LLM
- •多任务适应：为同一基础模型快速适配多个下游任务而不重复全量训练
- •实验研究：在学术研究中快速测试不同微调策略的效果对比
