What Is JSON Output in LLMs?

DEFINITION

JSON (JavaScript Object Notation) outputs from Large Language Models (LLMs) are outputs that are in a structured format. This will mean the LLM will return key-value pairs with arrays and nested objects. This means we can provide data to applications. Depending on the model and platform being used there may be features available to make sure the output is structured, for example schemas or tools. The JSON will not necessarily be factually correct though.

Importance of JSON outputs from LLMs

  • Structured Data – Information returned by the AI will be structured with expected fields.
  • Integration – Makes it easier to process outputs in applications.
  • Automation – Can be used for automation.
  • Consistent – Makes it more consistent.
  • Validation – Applications can validate the response against a schema.

Use Cases of JSON outputs from LLMs

  • Extracting invoice numbers, dates and amounts from documents.
  • Creating structured product attributes for e-commerce catalogs.
  • Returning categorized customer support requests.
  • Turning unstructured business information into structured data.
  • Providing structured arguments for tools and enterprise APIs that are supported.
