VerifiedLangChain4J provides annotation-driven Function Calling encapsulation, allowing Java programmers to directly expose ordinary methods to large models using the @Tool annotation.75% similarUnverifiedLangChain框架在Function Calling基础上提供了统一的Tool接口层，使同一套Agent代码可以无缝切换不同的底层模型74% similarUnverifiedLangChain 1.3's create_tool_calling_agent natively supports the parallel tool calling feature.73% similarVerifiedLangChain provides the FewShotPromptTemplate (few-shot prompt template) tool, which guides large models to understand task intent by embedding a small number of examples into the prompt.72% similarUnverifiedLangChain is currently the most widely adopted Agent framework; its Tool abstraction allows any Python function to be wrapped as a callable tool.71% similar
