Pros
- +Hybrid approach combining visual workflow building with full JavaScript/Python coding capabilities when needed
- +AI-native platform with LangChain integration for building sophisticated AI agent workflows using custom data and models
- +Fair-code license ensures source code transparency with self-hosting options, providing data control and deployment flexibility
- +显著的成本节约效益 - 10% token 减少可为大企业节省大量 API 费用，投资回报率极高
- +即插即用设计 - 无需模型权重访问，支持多种优化算法，与现有 NLU 系统无缝集成
- +智能保护机制 - 提供保护标签功能确保关键信息不被误删，支持顺序优化和详细指标分析
Cons
- -Requires technical knowledge to fully leverage coding capabilities and advanced features
- -Self-hosting demands infrastructure management and maintenance overhead
- -Fair-code license restricts commercial usage at scale without enterprise licensing
- -存在压缩与性能权衡 - 压缩率提升会导致模型性能下降，需要仔细权衡
- -没有通用优化器 - 不同任务需要选择不同的优化策略，需要一定的调试和优化经验
