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 model generates responses that frequently repeat phrases or words. Which parameter adjustment is most likely to fix this?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase repetition penalty
Increasing the repetition penalty directly discourages the model from selecting tokens that have already appeared in the generated sequence, thereby reducing repetitive phrases or words. This parameter works by subtracting a fixed penalty from the logits of previously generated tokens before applying the softmax function, making them less likely to be chosen again.
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 top_k
Why it's wrong here
Higher top_k increases the pool of tokens, which may encourage diversity but is less effective than repetition penalty.
✗
Increase temperature
Why it's wrong here
Higher temperature increases randomness, not necessarily reducing repetition.
✓
Increase repetition penalty
Why this is correct
Correct: Repetition penalty specifically reduces the likelihood of repeating tokens.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
Increase max output tokens
Why it's wrong here
Longer output may actually allow more repetition.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse repetition penalty with diversity-promoting parameters like temperature or top_k, mistakenly believing that increasing randomness or narrowing token selection will fix repetition, when in fact those adjustments can worsen the problem.

Longer output may actually allow more repetition.
Detailed technical explanation
How to think about this question
Under the hood, repetition penalty is applied as a multiplicative or subtractive factor to the logits of tokens that have already been generated, with typical values ranging from 1.0 (no penalty) to 2.0 (strong penalty). A subtle behavior is that the penalty is often applied per token occurrence, meaning frequently repeated tokens receive increasingly larger penalties, which can sometimes cause the model to abruptly switch topics or produce unnatural phrasing if set too high. In real-world scenarios, such as long-form text generation or dialogue systems, tuning this parameter is critical to balance coherence and novelty.
KKey Concepts to Remember

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 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.
