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
✓
Increase the frequency penalty
Frequency penalty reduces the chance of repeating tokens that have already appeared, directly mitigating repetition. Presence penalty also helps but is broader; frequency penalty is more targeted.
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 max tokens
Why it's wrong here
Max tokens limits length, not repetition.
- ✗
Decrease top-p to 0.5
Why it's wrong here
Lower top-p reduces vocabulary diversity, which might increase repetition.
- ✓
Increase the frequency penalty
Why this is correct
Frequency penalty penalizes tokens based on how often they have appeared, reducing repetition.
- ✗
Increase temperature to 0.9
Why it's wrong here
Higher temperature increases randomness but may not specifically reduce repetition; could make output less coherent.
