Structured vs Unstructured Outputs

Mem0 supports two types of OpenAI LLM formats, each with its own strengths and use cases:

​
Structured Outputs

Structured outputs are LLMs that align with OpenAI’s structured outputs model:
  • Optimized for: Returning structured responses (e.g., JSON objects)
  • Benefits: Precise, easily parseable data
  • Ideal for: Data extraction, form filling, API responses
  • Learn more: OpenAI Structured Outputs Guide

​
Unstructured Outputs

Unstructured outputs correspond to OpenAI’s standard, free-form text model:
  • Flexibility: Returns open-ended, natural language responses
  • Customization: Use the response_format parameter to guide output
  • Trade-off: Less efficient than structured outputs for specific data needs
  • Best for: Creative writing, explanations, general conversation
Choose the format that best suits your application’s requirements for optimal performance and usability.
