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.81% similarUnverified通过JSON Schema约束模型输出，可使tags字段永远存在、永远是数组，整体结构保持绝对稳定，供下游代码直接消费78% similarVerifiedJSON Schema is a specification for describing and validating JSON data structures, capable of defining field requirements, data types, and value ranges.77% 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.76% similarUnverifiedJSONL格式支持追加写入，中断前的消息可安全落盘，相比JSON数组存储更适合AI代理会话记录场景75% similar
