Structured Output Reference

Use this page when you need exact structured-output terminology and types rather than the task-first usage guide.

​

Core types

• OutputSchema
• MeerkatSchema
• SchemaCompat
• SchemaFormat
• SchemaWarning
• CompiledSchema

​

Request-side controls

• output_schema
• structured_output_retries
• provider-specific lowering / strictness

​

Result-side fields

• structured_output
• schema_warnings
• extraction-turn retry behavior

​

Validation note

Schema validation depends on the jsonschema feature. Without it, Meerkat still parses JSON but skips schema validation.
