  • synthesize_schema (Optional[bool], optional): Whether to enable the use of a schema assistant model to automatically synthesize the schema if validation fails or no valid schema is provided. (default: :obj:False)
  • synthesize_schema_model (Optional[BaseModelBackend], optional): An assistant model (e.g., an LLM model) used to synthesize the schema if synthesize_schema is enabled and no valid schema is provided. (default: :obj:None)
  • synthesize_schema_max_retries (int, optional): The maximum number of attempts to retry schema synthesis using the schema assistant model if the previous attempts fail. (default: 2)
  • synthesize_output (Optional[bool], optional): Flag for enabling synthesis output mode, where output is synthesized based on the function’s execution. (default: :obj:False)
  • synthesize_output_model (Optional[BaseModelBackend], optional): Model used for output synthesis in synthesis mode. (default: :obj:None)
  • synthesize_output_format (Optional[Type[BaseModel]], optional): Format for the response when synthesizing output. (default: :obj:None)
