AWS Certified AI Practitioner AIF-C01 Practice Question

Fine-tuning continues the training of an existing foundation model on a smaller, domain-specific dataset so that the model's internal weights adjust to the organization's vocabulary, writing style, or task requirements. Embedding creation only produces vector representations of text and does not modify the model's core parameters. Prompt engineering guides the model at inference time without any weight updates. Model evaluation measures performance but does not change how the model is trained.
