AWS Certified AI Practitioner (AIF-C01) — Question 267

An AI practitioner is using a large language model (LLM) to create content for marketing campaigns. The generated content sounds plausible and factual but is incorrect.
Which problem is the LLM having?

Answer options

• A. Data leakage
• B. Hallucination
• C. Overfitting
• D. Underfitting

Correct answer: B

Explanation

Hallucination is the phenomenon where a large language model (LLM) generates content that is highly fluent and plausible but factually inaccurate. Overfitting and underfitting are traditional machine learning problems related to how well a model generalizes to new data, while data leakage occurs when training data contains information about the target variable that would not be available during inference.
