AIF-C01 Fundamentals of Generative AI Practice Question
A company uses Amazon Bedrock to generate marketing content. They want to reduce costs while maintaining response quality. Which action is most effective?
⚠ Common exam trap
Test-takers frequently confuse cost-reduction strategies with performance-enhancing strategies, assuming that fine-tuning or caching always saves money, when in fact the most direct lever is selecting the smallest capable model for the job.

Correct answer & explanation
✓
Select a smaller foundation model that still meets accuracy requirements.
The most effective cost-reduction strategy because smaller foundation models (FMs) have fewer parameters, resulting in lower compute and inference costs per request. If the smaller model still meets the required accuracy benchmarks for the marketing content task, it directly reduces operational expenditure without sacrificing quality. Amazon Bedrock offers a range of FMs (e.g., from large models like Claude 3 Opus to smaller ones like Claude 3 Haiku), allowing you to match model size to task complexity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Fine-tune a larger model to improve accuracy and reduce retries.
Why it's wrong here
Fine-tuning is expensive; a smaller model is cheaper.
- ✗
Increase the temperature parameter to get shorter responses.
Why it's wrong here
Temperature affects randomness, not length or cost directly.
- ✓
Select a smaller foundation model that still meets accuracy requirements.
Why this is correct
Smaller models have lower per-token costs and are faster.
- ✗
Cache previous responses to reuse for similar prompts.
Why it's wrong here
Caching can reduce repeated calls but is not the most effective for variable prompts.
