Unverified提示词工程通过角色定义、输出格式约束（如JSON Schema）、少样本示例等手段约束模型概率性输出76% similarUnverifiedConstrained output refers to restricting the model to produce only results that conform to predefined rules, common forms of which include fixed-option selection, structured data conforming to a JSON schema, and specific enumeration values.75% similarUnverifiedLarge language models' understanding of JSON structure is probabilistic, and when processing longer structured outputs, type degradation occurs due to attention mechanism weight decay on earlier context, such as serializing arrays as strings or writing numbers as strings.73% similarVerifiedFunction Calling uses task-specific fine-tuning to enable models to output structured content conforming to a predefined JSON Schema under specific conditions.69% similarUnverifiedThe practice of restricting model output to observable facts is referred to in machine learning engineering as 'Output Constraining' or 'Structured Prompting'.68% similar
