Which option is a disadvantage of using generative AI models in production systems?

Comprehensive and Detailed Explanation From Exact AWS AI documents:

A known limitation of generative AI models is their tendency to hallucinate, meaning they may generate plausible but incorrect or fabricated information.

AWS generative AI guidance highlights:

Non-deterministic behavior

Risk of incorrect outputs

Need for validation, monitoring, and guardrails in production systems

Why the other options are incorrect:

High accuracy (A) is an advantage, not a disadvantage.

Deterministic behavior (B) is generally not true for generative models.

Negligible resource usage (C) is incorrect; generative models are resource-intensive.
