Structured output
What is Structured output?
A feature of LLMs that constrains the model to produce outputs in a defined format — such as JSON, XML, or a custom schema. Critical for integrating AI into software systems where outputs must be reliably parsed by downstream code.
Example in practice
A developer building an AI invoice processor would use structured output to guarantee the model returns a consistent JSON object with amount, vendor, and date fields — making the output directly parseable by accounting software.
