SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

It eliminates the tedious work of writing many prompts and manually calling image APIs by batch-generating images from structured, randomly sampled prompt templates.

Core Features & Use Cases

Random prompt sampler: Produces a repeatable set of “random but structured” prompts by combining subjects, styles, and lighting.
OpenAI Images API rendering: Generates images for GPT image models and DALL-E models with model-appropriate parameter defaults.
Instant browsing output: Writes generated files plus a prompts.json mapping and an index.html thumbnail gallery for quick review.
Use Case: When you need quick concept variations for a creative direction sprint, you can generate 16 themed images at once and review them in a local gallery.

Quick Start

Run the generator to create a gallery by ensuring OPENAI_API_KEY is set, then executing one prompt batch and opening the resulting index.html in your browser.

FAQPage Schema

How do I batch-generate images using the OpenAI Images API?▼

Batch image generation works by sampling structured random prompt templates and sending HTTPS requests to the OpenAI Images API. It supports both GPT image models and DALL-E variants by applying model-specific defaults for size, quality, background, and output format.

Can I generate a local image gallery from OpenAI API outputs?▼

Generating a local image gallery involves saving decoded base64 data or downloaded image URLs to an output directory. The Skill automatically produces an index.html thumbnail gallery and a prompts.json mapping file for quick visual review.

Do I need an OPENAI_API_KEY to use this image generation script?▼

An OPENAI_API_KEY is required as an environment variable to authenticate requests. The script sends HTTPS requests to api.openai.com/v1/images/generations, making the API key mandatory to render the batch image prompts successfully.

What's the best way to create random but structured prompts for visual ideation?▼

Creating structured random prompts is best achieved by sampling combinations of predefined subjects, styles, and lighting parameters. This approach produces a repeatable set of random but structured prompts, enabling rapid visual ideation for creative sprints.

Does this batch image generation tool support DALL-E and GPT image models?▼

Both DALL-E and GPT image models are supported. The generator applies model-appropriate parameter defaults for size, quality, background, output format, and style constraints to ensure compatibility across different OpenAI image generation variants.
