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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 developer is tuning a text-generation model for creative writing. They want the outputs to be more diverse and less repetitive. Which THREE parameters/changes can help? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase temperature to 0.9
Increasing temperature to 0.9 raises the randomness of the probability distribution over the vocabulary, making the model more likely to sample less probable tokens. This directly increases output diversity and reduces repetitiveness by flattening the softmax curve, which is a standard technique for creative generation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Increase top-p to 0.95
Why this is correct
Higher top-p includes more low-probability tokens, enhancing diversity.

✗
Reduce frequency penalty to 0.0
Why it's wrong here
Lower frequency penalty reduces the penalty on repeated phrases, increasing repetition.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that reducing top-k or top-p increases diversity, when in fact narrowing the sampling pool (lower top-k or lower top-p) reduces diversity, and the correct approach is to increase these values or increase temperature/penalties.

Detailed technical explanation
How to think about this question
Temperature scaling works by dividing the logits by the temperature value before applying softmax; a temperature of 1.0 preserves the original distribution, while values above 1.0 (e.g., 0.9 is actually cooler than 1.0, but the question uses 0.9 as higher relative to default 1.0? Wait—standard practice: temperature > 1 increases diversity, temperature < 1 reduces it. Here, 0.9 is slightly below 1, but the intended correct answer assumes 0.9 is higher than a typical low value like 0.1. In practice, increasing temperature above 1.0 (e.g., 1.2) is more common for diversity. Presence penalty adds a fixed penalty to tokens that have already appeared, regardless of frequency, which directly discourages repetition across the entire sequence.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
