- A
Add more examples of toxic content to training
Why wrong: This could inadvertently teach the model to generate toxic content.
- B
Increase the filter threshold
Why wrong: Higher threshold means more lenient filtering, worsening toxicity.
- C
Use RLHF with human feedback to reduce toxicity
Correct: RLHF explicitly trains the model away from toxic outputs.
- D
Decrease the model's temperature
Why wrong: Lower temperature may reduce randomness but not specifically address toxicity.

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.
Despite applying safety filters, a generative AI model still produces toxic outputs in some cases. Which additional technique should be applied?

Correct answer & explanation
✓
Use RLHF with human feedback to reduce toxicity
RLHF (Reinforcement Learning from Human Feedback) directly addresses toxicity by using human evaluators to rank model outputs, then fine-tuning the model to prefer less toxic responses. This technique teaches the model to avoid harmful patterns that safety filters might miss, as filters are static and can be bypassed by adversarial prompts or nuanced toxicity.
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.
- ✗

Why it's wrong here
This could inadvertently teach the model to generate toxic content.
- ✗
Increase the filter threshold
Why it's wrong here
Higher threshold means more lenient filtering, worsening toxicity.
- ✓
Use RLHF with human feedback to reduce toxicity
Why this is correct
Correct: RLHF explicitly trains the model away from toxic outputs.

- ✗
Decrease the model's temperature
Why it's wrong here
Lower temperature may reduce randomness but not specifically address toxicity.
Common exam traps
Common exam trap: answer the scenario, not the keyword
A common misconception is that adjusting static parameters (like temperature or filter thresholds) can solve alignment problems, when in fact dynamic human-in-the-loop methods like RLHF are required for nuanced safety issues.
Detailed technical explanation
How to think about this question
RLHF works by first collecting a dataset of human preferences comparing model outputs, then training a reward model to predict human preferences, and finally fine-tuning the base model using Proximal Policy Optimization (PPO) to maximize the reward signal. This approach is particularly effective for nuanced safety issues like subtle hate speech or context-dependent toxicity that simple keyword filters cannot catch. In production systems, RLHF is often combined with adversarial testing and red-teaming to iteratively improve robustness.
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.
