AIF-C01 Applications of Foundation Models Practice Question
A marketing team is using a foundation model to generate marketing copy. Which THREE of the following should they consider to ensure responsible and cost-effective use?
⚠ Common exam trap
AWS often tests the misconception that model size (parameters) is a key cost driver, but in practice, cost is tied to token consumption and inference infrastructure, not just parameter count, and latency is a performance metric, not a cost or responsibility factor.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Bias mitigation to avoid unfair stereotypes
Option A (Bias mitigation to avoid unfair stereotypes) is correct because foundation models can reproduce or amplify biases present in their training data, and marketing copy that relies on unfair stereotypes creates reputational, legal, and ethical risk, so teams should apply bias detection and mitigation techniques. Option B (Cost per token for the model) is correct because foundation models are typically billed by input and output tokens, so tracking cost per token directly supports cost-effective use and lets the team choose the most economical model or prompt design for the workload. Option D (Toxicity detection in generated content) is correct because generative models can produce offensive, harmful, or brand-damaging text, so toxicity detection and filtering are needed to keep marketing content responsible and safe to publish. Option C (Model size, number of parameters) is not one of the required answers here because parameter count is only an indirect proxy for capability and cost, and by itself it does not ensure responsible or cost-effective use. Option E (Latency of model inference) is not one of the required answers because inference latency affects user experience and responsiveness, not the responsible-use or token-cost concerns the scenario asks about.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Bias mitigation to avoid unfair stereotypes
Why this is correct
Bias mitigation directly addresses fairness, a core responsible-AI dimension for generative marketing copy that could otherwise propagate stereotypes. It satisfies the stem's responsible-use constraint by reducing discriminatory outputs, complementing cost controls. Unlike accuracy or latency tuning, bias mitigation targets the ethical risk inherent in open-ended text generation.
- ✓
Cost per token for the model
Why this is correct
Token pricing determines the charge for each generated and input token, so selecting a model with a lower cost per token directly controls spend. This satisfies the cost-effective use requirement for high-volume marketing copy generation.
- ✗
Model size (number of parameters)
Why it's wrong here
Parameter count affects capability and inference cost, but the stem asks which factors ensure responsible and cost-effective use; model size alone neither governs data privacy, bias mitigation nor token-based pricing decisions. It is tempting because larger models often improve output quality, so parameter count matters when accuracy outweighs budget.
- ✓
Toxicity detection in generated content
Why this is correct
Toxicity detection screens generated copy for harmful, offensive or abusive language before publication, directly satisfying the responsible-use requirement in the stem. Foundation models can reproduce biased or toxic patterns from training data, so filtering output protects brand reputation and audiences. It addresses safety, not cost, but the stem asks for both dimensions across three selections.
- ✗
Latency of model inference
Why it's wrong here
Inference latency affects user experience, not responsible or cost-effective use; token consumption and pricing drive cost. It tempts because latency is a genuine operational metric for generative AI workloads, but it belongs to performance planning rather than responsibility or budget control.
