Unverified50% confidenceDecision RuleExact time
Fields generated as required in the schema are commitments the model must fulfill, so the model-side type should contain only fields the model can genuinely determine, and any metadata filled in by the application (such as source tags) must be stripped from that type.

UnverifiedWhen handing the schema to the model, if the model is responsible for producing the raw input, `io: "input"` should be used.72% similarUnverifiedIn tool calling, the model may generate parameters that do not conform to the Schema, omit required fields, or confuse tools across multiple rounds of calls, so production environments usually need a validation and fault-tolerance layer between the model and the tools.69% 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.68% similarUnverifiedA context constructor is the code layer responsible for assembling, formatting, and filtering inputs before data is fed into the model; changes to it do not affect model weights or prompt templates but can alter the premises of model reasoning.68% similarUnverifiedWhen using structured output, it is recommended that the Schema design align with real business fields and avoid excessive nesting that leads to unstable model performance.68% similar
