Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the temperature.
Why it's wrong here
Temperature increases unpredictability, making JSON structure less likely.
- ✗
Add 'output must be JSON' to the prompt.
Why it's wrong here
While helpful, it is less reliable than the native JSON mode feature.
- ✗
Post-process the output with a regex script.
Why it's wrong here
Regex is brittle and does not guarantee the model will produce valid structure.
- ✓
Enable JSON mode/Response Format in the API configuration.
Why this is correct
This feature forces the model to output valid JSON.
