AIF-C01 Practice Question: Reduce the cost of running a large number of…
A company wants to reduce the cost of running a large number of inference requests for a text classification task. The responses can tolerate a slight delay. Which cost optimization strategy should they implement?
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
✓
Use batch inference to process multiple requests asynchronously
Batch inference processes multiple requests together, reducing cost per request at the expense of higher latency. Model caching can help if there are many repeated requests, but batch inference is more general. Switching to a larger model increases cost. Using a vector store is unrelated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Store the training data in a vector store for faster retrieval
Why it's wrong here
Vector stores are for RAG, not for reducing inference costs on classification tasks.
- ✓
Use batch inference to process multiple requests asynchronously
Why this is correct
Batch inference groups requests, lowering per-request cost, and is suitable when real-time responses are not required.
- ✗
Use a larger, more accurate model to reduce the number of retries
Why it's wrong here
Larger models are more expensive per request and may increase costs, not reduce them.
- ✗
Implement model caching to reuse results for identical prompts
Why it's wrong here
Caching helps if prompts repeat, but batch inference addresses volume more directly.
