AWS Certified AI Practitioner (AIF-C01) — Question 81

Which option is a benefit of ongoing pre-training when fine-tuning a foundation model (FM)?

Answer options

• A. Helps decrease the model's complexity
• B. Improves model performance over time
• C. Decreases the training time requirement
• D. Optimizes model inference time

Correct answer: B

Explanation

The correct answer is B because ongoing pre-training allows the model to adapt and improve its performance as it learns from more data. Options A, C, and D do not accurately reflect the primary benefit of pre-training, which focuses on enhancing the model's ability rather than its complexity, training duration, or inference speed.
