AIF-C01 Practice Question: A data scientist is using Amazon Bedrock to…
A data scientist is using Amazon Bedrock to generate product descriptions. They notice the output is often repetitive and lacks creativity. Which combination of parameter adjustments is MOST likely to produce more diverse and less repetitive output?
⚠ Common exam trap
AWS often tests the misconception that increasing temperature alone is sufficient for diversity, but candidates forget that top-p must also be increased to avoid the model repeatedly sampling from a narrow set of high-probability tokens.

Correct answer & explanation
✓
Increase temperature and increase top-p
Increasing temperature raises the probability of sampling lower-probability tokens, which increases randomness and diversity. Increasing top-p (nucleus sampling) expands the set of tokens considered for sampling, further reducing repetitiveness. Together, these adjustments encourage the model to explore a wider range of possible continuations, producing more creative and less repetitive output.
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 and decrease top-p
Why it's wrong here
This makes output more deterministic and repetitive, worsening the problem.
- ✗
Decrease temperature and increase top-p
Why it's wrong here
Lower temperature reduces randomness; higher top-p may not compensate enough for repetitive output.
- ✗
Increase temperature and decrease top-p
Why it's wrong here
Increasing temperature helps diversity, but decreasing top-p may counteract that effect by narrowing token selection.
- ✓
Increase temperature and increase top-p
Why this is correct
Higher temperature flattens probability distribution; higher top-p expands the set of candidate tokens, both promoting diversity.
