What is Output format?

Also called: structured output · response format

The output format is the shape you ask for — table, numbered steps, JSON, three variants, 120 words — and the cheapest instruction that most improves usability.

Left alone, a model writes prose with bold headings. Telling it the format changes how the answer is organised and how you can use it: a table you can scan, steps you can follow, JSON your code can parse, a length that fits the slide.

For software, structured formats (JSON with a schema, or a fixed markdown template) make the output reliable enough to automate. For humans, "table with these columns" or "five bullets, one sentence each" is usually enough.

Example
Output as a markdown table with columns: option · cost · risk · my next step. Then one line: the option you'd choose and why.
How to use it well
  1. Name the structure, the length, and what to leave out.
  2. For JSON, give the exact keys and one filled example.
  3. Ask for the final answer separately from any reasoning.
