Your GPU's new night shift: automated prompt farming

What it does

This is a Python automation wrapper around three popular open-source image generation pipelines. You write a plain text file listing subjects and styles—“a monkey on a motorcycle” × “by Picasso”—and it cranks out the full combinatorial matrix locally. It supports Stable Diffusion, CLIP-guided diffusion (Disco Diffusion), and VQGAN+CLIP, with optional ESRGAN upscaling baked in.

The interesting bit

The author didn’t train models or write diffusion code; they solved the boring part that everyone hits after their first 50 manual prompts. Keyboard shortcuts (Windows-only) let you pause the queue with CTRL+SHIFT-P when you need your GPU back for actual work. Output JPEGs carry full EXIF metadata so you can reconstruct what the hell you generated three months later.

Key highlights

• Supports combinatorial batch generation: n subjects × m styles = automated matrix of outputs
• Three backends: Stable Diffusion (recommended), VQGAN+CLIP, and Disco Diffusion
• Optional ESRGAN/GFPGAN upscaling chain
• GPU pause/resume and prompt file hot-reload (Windows only)
• EXIF metadata embedding for reproducibility

Caveats

• Effectively deprecated: the author launched Dream Factory in September 2022 and states this repo will only receive bug fixes, not new features
• Setup is manual and finicky: multiple git clones, checkpoint downloads, conda environment wrangling, and platform-specific path tweaks (Linux users must swap quote styles in curl commands)
• AMD GPU support is theoretical—ROCm PyTorch on Linux, completely untested by the author
• Keyboard controls don’t work on Linux or macOS

Verdict

Useful if you’re specifically running VQGAN or Disco Diffusion locally and need batch automation; otherwise the author’s newer Dream Factory project is the logical migration. Skip entirely if you want a one-click installer or cloud API convenience.
