Study AIF-C01 GenAI Business Value, Limits and Model Selection: key concepts, common traps, and exam decision cues.
AWS wants candidates to understand that GenAI is powerful, but not magic. Strong answers match it to summarization, drafting, transformation, search assistance, or conversational use cases while still accounting for hallucinations, latency, cost, and business risk.
| Situation | Better instinct |
|---|---|
| the answer must be deterministic and explainable with clear rules | a rule-based system may be stronger |
| the problem is really prediction from labeled tabular data | classic ML may be the better lane |
| the question highlights cost and latency over creativity | a smaller model or narrower pattern may fit better |
| the model lacks fresh private knowledge | retrieval and grounding matter more than simply choosing a bigger model |
| Risk or limit | Why it matters |
|---|---|
| Hallucination | model may generate plausible but wrong output |
| Nondeterminism | outputs can vary across runs |
| Latency and cost | larger models or longer contexts can cost more and respond slower |
| Freshness limits | pretrained model knowledge may not reflect the newest business data |
The best model is not always the largest. AIF-C01 usually rewards the choice that balances:
