1.5 – Training a GPT To Create Specific Image Prompts Lesson

Lesson Overview

This lesson focuses on setting up custom GPTs designed to generate image prompts automatically, using a specific Scenic prompt structure. The purpose is to save time and add flexibility when you need new ideas for images, whether for business uses or creative experiments. Instead of manually crafting every image prompt, you’ll learn to build your own tools that handle the heavy lifting by following clear, repeatable instructions you provide.

You’ll see how to create two separate GPTs: one that produces polished, business-friendly stock image prompts, and another that offers playful, imaginative prompts suitable for personal or creative projects. With this approach, you can jump from an idea—like “conference room”—directly to a rich, detailed prompt that’s ready for ChatGPT’s image generation.

This is particularly helpful if you often need consistent output or want to inspire yourself with new visual directions with minimal effort. The skill is useful for creators, small business owners, marketers, educators, and anyone looking to streamline the image ideation process with AI.

Who This Is For

Wondering if you should follow this lesson? It’s a good fit if you’re:

• Someone who wants to automate image prompt creation for rapid brainstorming
• Marketers and content creators needing professional visuals quickly
• Business users designing marketing, web, or app imagery
• Artists and designers who want to spark new ideas for creative projects
• Educators looking to generate illustrative materials for lessons
• Anyone curious about building reusable, custom GPTs for specific tasks

Where This Fits in a Workflow

Setting up your own prompt-generating GPTs fits smoothly into the early creative stage of any project that relies on visuals. For example, if you’re launching a new product and need stock photos for your website, your business-focused GPT will give you ready-made prompts to generate those images with just a quick idea. Or, if you’re stuck for inspiration for a fantasy game poster, the creative GPT can serve up new concepts with just a few clicks.

Whether you’re brainstorming, developing concepts, or producing supporting visuals, these custom GPTs help you start fast and maintain consistency throughout your project by using a defined structure across every prompt.

Technical & Workflow Benefits

Previously, generating image prompts required repeatedly writing out detailed instructions for each new idea. This not only slowed down projects but often resulted in inconsistent prompts—especially when switching between business and creative focuses. By creating custom GPTs using the guided setup, you replace all that manual work with reusable AI tools that understand your exact requirements.

For a marketing campaign, for example, you can instantly turn a list of product features or scenes into fully structured prompts, maintaining professional tone and saving considerable planning time. In creative scenarios, you get tailored prompts that keep your experiments fun and fresh without starting from scratch. Adjustments and updates to your GPTs are easy—just tweak the settings when you need a new style or instruction.

Overall, this raises the quality and effectiveness of your image creation routine while freeing you to focus more on idea development or execution.

Practice Exercise

Try applying this method by creating your own custom GPTs for two different needs:

1. Choose two project types: for instance, one for business stock imagery (like "marketing brochures") and one for creative outputs (such as "storybook covers").
2. Use the GPT builder in ChatGPT to create each GPT:
   - Add appropriate names, instructions, and example prompts related to your chosen focus areas.
   - Once finished, test them by entering a simple topic and see what prompts they generate.
3. Compare the output:
   - Which GPT gave you a more helpful prompt for your specific scenario?
   - Did you need to update any instructions for better results?

Reflect on how much faster or easier this process feels compared to manually writing prompts each time.

Course Context Recap

You’re now building on the skills you’ve learned around image prompt structures in previous lessons, adding the power of automation via custom GPTs. Prior lessons introduced the Scenic prompt approach; this chapter turns it into a reusable tool. Next, you’ll explore how to further enhance these systems or generate images with the latest available ChatGPT models. Continue ahead to see how these prompt generators connect with image creation in real-world scenarios or revisit earlier lessons to strengthen your foundation.
