Multi-Step Prompt Generation Workflow for Product Posters
A detailed workflow instruction for generating complete, system-level prompts for product posters using LLMs (GPT, Claude, Gemini) and then executing them on Nano Banana Pro. The process involves the LLM extracting selling points, determining style, and layout, followed by the image model generating the final poster, with specific constraints on logo consistency and product appearance.
Prompt
Input this instruction, allowing the AI to complete the entire process step-by-step: extracting selling points, determining style, determining layout, and finally generating a complete, system-wide prompt. Finally, give the AI-generated prompt to the Nano Banana Pro model (it must be Pro). You can first provide some overall style prompts separately as general constraints. Then, whether generating images individually or in batches using third-party tools, it is possible.
