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
输入这条指令，让AI按照整个流程一步一步完成卖点提取、风格确定、排版确定，最后生成完整的全系统的提示词。
最后将AI生成的提示词给到nano bananapro模型（一定得是pro），可以单独先给一些整体风格的提示词，作为整体约束。然后不管是单个依次生成，还是用第三方的工具批量生成，都可以。Images
