AI0-001 Few-shot prompting Practice Question
A team is deploying a fine-tuned LLM for code generation. They need to ensure the model output is always valid JSON. Which prompt engineering technique should they use?
⚠ Common exam trap
Candidates might mistakenly think that setting temperature to 0 will guarantee valid JSON output, but temperature controls randomness, not format. The only way to enforce a specific format with standard prompting is through explicit instructions and examples.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Few-shot examples of valid JSON outputs
Few-shot prompting provides the model with examples of valid JSON outputs, conditioning it to mimic the format in its response. This is an effective technique for constraining output structure without requiring model retraining or special modes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Chain-of-thought prompting
Why it's wrong here
Chain-of-thought prompting guides reasoning but does not constrain the output to valid JSON. It is not designed for format enforcement.
- ✓
Few-shot examples of valid JSON outputs
Why this is correct
Correct. Providing few-shot examples of valid JSON outputs conditions the model to mimic that structure, making it the most direct technique listed.
- ✗
Temperature setting to 0
Why it's wrong here
Setting temperature to 0 reduces randomness but does not guarantee valid JSON. The model may still produce malformed JSON.
- ✗
Using a larger model variant
Why it's wrong here
Using a larger model variant may improve overall quality but does not specifically ensure valid JSON output without additional prompting techniques.
