Partially VerifiedStructured output imposes constraints on token generation during the decoding phase through JSON Schema or function-calling mechanisms, which is fundamentally different from requesting JSON-format output in the prompt.77% similarUnverified工具调用（Function Calling）要求模型稳定输出符合预定义Schema的结构化JSON，OpenAI、Anthropic等主流模型提供商引入了Constrained Decoding（约束解码）技术在生成时实时过滤不合法token72% similarUnverifiedThe core mechanism of Function Calling is that developers describe external function signatures in JSON Schema format, and the model outputs structured JSON invocation instructions that conform to the schema specification.71% similarUnverifiedJSON Mode only guarantees that the output is valid JSON without constraining the field structure; Structured Outputs enforces output conforming to a predefined JSON Schema at the syntactic level by applying a finite state machine (FSM) to constrain the token sampling path during the decoding phase.70% similar
