Which of these is a valid use case for generative AI models?

Generative AI models excel at creating new content, such as images, text, or audio, based on learned patterns. Generating photorealistic images from text prompts directly aligns with this capability, making it a valid use case for digital marketing where unique visual content is often needed. Improving network security with intrusion detection systems primarily involves anomaly detection and classification, which are typically handled by discriminative AI models. Enhancing database performance with optimized indexing is a database administration task, not an AI application. Analyzing financial data to forecast stock market trends is a predictive analytics task, often using machine learning models, but not typically generative AI.
