- A
Decrease temperature to 0.2
Lower temperature makes the model more deterministic, leading to more consistent outputs.
- B
Increase top-p to 0.9
Why wrong: Higher top-p allows more token choices, increasing variability.
- C
Increase presence penalty to 0.5
Why wrong: Presence penalty discourages repeating topics, making outputs less consistent.
- D
Decrease frequency penalty to 0.0
Why wrong: Frequency penalty reduces repetition of phrases; setting to zero doesn't improve consistency across questions.

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 data scientist is using Vertex AI generative AI studio to create a chatbot. The chatbot gives inconsistent answers to similar questions. Which parameter should they adjust to make responses more consistent?
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
✓
Decrease temperature to 0.2
Decreasing the temperature to 0.2 reduces the randomness of the model's token sampling, making the output more deterministic and consistent. Temperature controls the probability distribution over tokens; lower values make the model more likely to choose the highest-probability token, reducing variability in responses to similar questions.
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.
- ✓
Decrease temperature to 0.2
Why this is correct
Lower temperature makes the model more deterministic, leading to more consistent outputs.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Increase top-p to 0.9
Why it's wrong here
Higher top-p allows more token choices, increasing variability.
- ✗
Increase presence penalty to 0.5
Why it's wrong here
Presence penalty discourages repeating topics, making outputs less consistent.
- ✗
Decrease frequency penalty to 0.0
Why it's wrong here
Frequency penalty reduces repetition of phrases; setting to zero doesn't improve consistency across questions.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that increasing top-p or adjusting penalties improves consistency, when in fact temperature is the primary parameter for controlling output determinism.
Trap categories for this question
Keyword trap
Frequency penalty reduces repetition of phrases; setting to zero doesn't improve consistency across questions.
Command / output trap
Presence penalty discourages repeating topics, making outputs less consistent.
Detailed technical explanation
How to think about this question
Temperature works by scaling the logits (raw scores) before applying the softmax function; a temperature of 0.2 divides logits by 0.2, sharpening the distribution so that high-probability tokens dominate. In practice, for a customer support chatbot, setting temperature too high (e.g., 1.0) can cause the model to generate creative but inconsistent answers to the same query, while a low temperature ensures the model sticks to the most likely, factual response.
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 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.
