SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Batch generation of AI-generated images from prompts can be time-consuming and inconsistent. This Skill automates the process by sampling random prompts, sending them to the OpenAI Images API, and aggregating the results into a browsable gallery.

Core Features & Use Cases

  • Prompt sampling: Generates a variety of structured prompts to explore visual concepts without manual prompt crafting.
  • OpenAI Images API integration: Converts prompts into images across supported models (GPT image series, DALL-E 2/3) with size and quality controls.
  • Output gallery: Produces index.html and prompts.json to review, share, and reuse generated assets locally.
  • Use Case: Visual brainstorming for product design, marketing assets, or concept art with a quick gallery export.

Quick Start

Run the generator to create a gallery of images from prompts and open the resulting index.html.

FAQPage Schema
How do I batch generate AI images from prompts using the OpenAI Images API?▼

To batch generate AI images from prompts, this Skill samples structured prompts and sends them to the OpenAI Images API, aggregating the results into a local browsable gallery with index.html and prompts.json.

Does batch image generation work with DALL-E 2, DALL-E 3, and GPT image models?▼

Batch image generation works with DALL-E 2, DALL-E 3, and GPT image models. It applies model-specific defaults, controls size and quality, and limits DALL-E 3 to a single image generation per prompt.

What is the best way to automate visual brainstorming for multiple marketing assets?▼

The best way to automate visual brainstorming for marketing assets is sampling random structured prompts to generate multiple AI images, outputting a local gallery to review, share, and reuse the visual concepts.

How do I create a browsable local gallery of AI generated images?▼

You create a browsable local gallery of AI generated images by running the batch generator, which outputs index.html and prompts.json files in a local directory for reviewing the generated assets.

Are there limitations when using DALL-E 3 for batch image generation?▼

A limitation when using DALL-E 3 for batch image generation is that the model is restricted to a single image output per prompt, unlike other supported models that allow multiple image generations.
