AWS Certified AI Practitioner (AIF-C01) — Question 142

What does an F1 score measure in the context of foundation model (FM) performance?

Answer options

• A. Model precision and recall
• B. Model speed in generating responses
• C. Financial cost of operating the model
• D. Energy efficiency of the model’s computations

Correct answer: A

Explanation

The F1 score is a metric that combines both precision and recall, providing a balance between the two in evaluating model performance. Options B, C, and D do not relate to the assessment of precision and recall, focusing instead on speed, cost, and energy consumption, which are not captured by the F1 score.
