AIF-C01 Fundamentals of Generative AI Practice Question
A company is building a customer service chatbot using Amazon Bedrock. Which component of a foundation model determines the creativity and randomness of the generated responses?
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
✓
Temperature
The temperature parameter controls randomness. Higher values (e.g., >1) produce more creative but less focused outputs, while lower values (e.g., near 0) produce more deterministic responses.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Prompt template
Why it's wrong here
Prompt template structures the input but does not affect the generation randomness.
- ✓
Temperature
Why this is correct
Temperature scales the logits before softmax, controlling randomness. Lower values make outputs more deterministic.
- ✗
Max tokens
Why it's wrong here
Max tokens limits the length of the response but does not control randomness.
- ✗
Top-p
Why it's wrong here
Top-p (nucleus sampling) controls the cumulative probability threshold for token selection, affecting diversity but not directly randomness.
