language_models/structured_output

Pipes an LLM through an output parser, optionally wrapping the result to include the raw LLM response alongside the parsed output.

When includeRaw is true, returns { raw: BaseMessage, parsed: RunOutput }. If parsing fails, parsed falls back to null.

Creates the appropriate content-based output parser for a schema. Use this for jsonMode/jsonSchema methods where the LLM returns JSON text.

• Zod schema -> StructuredOutputParser (Zod validation)
• Standard schema -> StandardSchemaOutputParser (standard schema validation)
• Plain JSON schema -> JsonOutputParser (no validation)

Creates the appropriate tool-calling output parser for a schema. Use this for function calling / tool use methods where the LLM returns structured tool calls.

• Zod schema -> parser with Zod validation
• Standard schema -> parser with standard schema validation
• Plain JSON schema -> parser with no validation
