When you have a labeled dataset and need to scale a generative AI solution for more complex or diverse product categories, fine-tuning the foundation model with your dataset is the best approach for consistent, accurate tagging.

D is correct:

“Fine-tuning a foundation model with your labeled data allows the model to generalize to new categories and improve tagging accuracy for your inventory.”

(Reference: Amazon Bedrock Fine-Tuning, AWS Generative AI)

A (zero-shot) and B (prompt templates) do not leverage the labeled data or scale as accurately.

C (continued pre-training) uses unlabeled data, not labeled.
