Structured output
Structured output asks for a response that matches a Pydantic model, TypedDict, dataclass, or JSON Schema. Your code receives fields instead of scraping sentences.
Tiny example
Section titled “Tiny example”from pydantic import BaseModel, Field
class Triage(BaseModel): priority: str = Field(description="low, medium, or high") reason: str
triage_model = model.with_structured_output(Triage)result = triage_model.invoke("Payment failed for every customer.")print(result.priority)For an agent, pass the schema as response_format=Triage; the validated value appears under result["structured_response"].
Failure note
Section titled “Failure note”A valid object can still be wrong. Schema validation proves shape and types, not factual correctness. Provider support also differs; check whether the integration uses native structured output, tool calling, or another method.
