Question 64 of 100 | ← Chapter 1

Which metric measures the operational efficiency of a running generative AI model?

• A. Customer Satisfaction Score (CSAT)
• B. Training time per epoch
• C. Average response time ✓
• D. Number of training instances

Correct Answer: C. Average response time

Explanation

This question tests understanding of operational AI metrics. Operational efficiency refers to how quickly and consistently a deployed model serves inferences. Average response time directly quantifies latency—the time between input submission and output delivery—and is a core service-level indicator for production AI systems. CSAT (Option A) measures subjective user perception; training time per epoch (Option B) and number of training instances (Option D) relate to development—not runtime—efficiency. Thus, Option C is the correct operational efficiency metric.
