A marketing team wants to use a generative AI model to create product descriptions for...

The core problem described is a lackluster and generic output that fails to capture the desired tone and key information (environmental benefits). This is a classic limitation of zero-shot prompting (a brief, un-detailed prompt), where the generative AI model relies solely on its general training data and lacks the necessary context to produce a highly relevant and engaging response. The solution is to improve the quality of the prompt itself, a process known as Prompt Engineering.

Option A, training the model, is an expensive and time-consuming process (fine-tuning) that is usually unnecessary for stylistic or content-specific guidance that can be achieved with a good prompt. Options C and D control the length and creativity, respectively, but don't inject the missing information or brand requirements.

Adding details to the prompt is the most immediate and effective technique to guide the model. By specifying the target audience (e.g., eco-conscious consumers), the desired tone (e.g., enthusiastic, persuasive), and mandatory keywords (e.g., "sustainable," "BPA-free," "ocean-friendly"), the marketing team is effectively providing the model with the necessary constraints and context to produce a description that is tailored to their brand and marketing goals. This technique is fundamental to improving the output of generative AI models without resorting to model customization.
