UnverifiedgenerateText is used to obtain a complete response at once, streamText achieves real-time token-by-token output via a streaming protocol, and generateObject combines structured output and JSON Schema validation to return JSON objects conforming to predefined types.72% similarUnverifiedIn the tool-calling mechanism, developers attach a tool description list in JSON Schema format when calling the LLM API, and the model outputs call parameters in structured JSON format72% similarUnverifiedThe underlying implementation of tool calling typically relies on the Function Calling protocol, where developers describe a tool's name, parameter types, and semantics in JSON Schema format, and the model outputs structured invocation instructions conforming to the protocol format.67% similarUnverifiedWhen defining tools with the @tool decorator, LangChain automatically generates a JSON schema from type annotations and docstrings to send to the model; the clearer the docstring, the higher the tool-calling accuracy.66% similarUnverifiedVercel AI SDK、LangChain.js等主流AI框架选择TypeScript作为首要语言64% similar
