- A
Increase temperature to 0.9 to encourage more creative outputs.
Why wrong: Higher temperature may cause the model to stray from the required facts.
- B
Provide three few-shot examples in the prompt that highlight the desired metrics.
Few-shot examples condition the model to replicate the structure and content of the examples.
- C
Set stop sequences to [' '] to ensure the model finishes each paragraph.
Why wrong: Stop sequences affect output length but not content completeness.
- D
Lower top_p to 0.5 to reduce the sampling pool.
Why wrong: Lower top_p may reduce diversity but does not ensure inclusion of specific metrics.

Generative AI Leader Practice Question: Techniques to Improve Generative AI Model Output
This Generative AI Leader practice question tests your understanding of techniques to improve generative ai model output. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A financial services firm is using a foundation model on Vertex AI to generate investment summaries from quarterly reports. The summaries are accurate but often miss key financial metrics and trends. The team cannot afford to fine-tune the model frequently. Which technique should they use to improve the completeness and relevance of the summaries without modifying the model?
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
✓
Provide three few-shot examples in the prompt that highlight the desired metrics.
Option B is correct because few-shot prompting provides the model with concrete examples of desired output structure and content, guiding it to include key financial metrics and trends without retraining. This technique leverages in-context learning, where the model generalizes from the examples in the prompt to produce more complete and relevant summaries, while avoiding the cost and latency of fine-tuning.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 temperature to 0.9 to encourage more creative outputs.
Why it's wrong here
Higher temperature may cause the model to stray from the required facts.
- ✓
Provide three few-shot examples in the prompt that highlight the desired metrics.
Why this is correct
Few-shot examples condition the model to replicate the structure and content of the examples.

- ✗
Set stop sequences to [' '] to ensure the model finishes each paragraph.
Why it's wrong here
Stop sequences affect output length but not content completeness.
- ✗
Lower top_p to 0.5 to reduce the sampling pool.
Why it's wrong here
Lower top_p may reduce diversity but does not ensure inclusion of specific metrics.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse hyperparameter tuning (temperature, top_p) with prompt engineering, assuming that increasing randomness or restricting token selection will improve output quality, when in fact few-shot examples directly teach the model the desired output structure without modifying the model.
Trap categories for this question
Command / output trap
Stop sequences affect output length but not content completeness.
Detailed technical explanation
How to think about this question
Few-shot prompting works by placing examples in the model's context window, which for models like PaLM 2 or Gemini on Vertex AI can be up to 32k tokens. The model uses the pattern in these examples to condition its generation, effectively performing in-context learning without weight updates. In practice, selecting examples that explicitly include missing metrics (e.g., 'Revenue grew 12% YoY') teaches the model to extract and surface similar data points from new reports, addressing the completeness gap.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
