Welcome to GridBulk

GridBulk started with a simple annoyance: exploring directions with AI image generation means generating one image at a time. Every variation is another request, another wait, another credit.

GridBulk flips that around: one prompt in, a grid of images out. The model generates a single high-resolution grid — from 1×1 up to 4×4 — and GridBulk splits it pixel-perfect into individual assets. One generation costs one credit, no matter how many images you get back.

How it works

Four steps, start to finish:

1. Choose a layout — pick your grid size and aspect ratio, from 1×1 to 4×4.
2. Write prompts — one prompt for all variations, or a different one for every cell.
3. Generate & split — the model renders a high-res grid, and we cut it into clean individual images.
4. Download — grab images one by one, or take them all as a ZIP.

What it's good for

GridBulk is built for the exploration phase, where you need breadth fast:

• Ad variants — test a dozen creative directions before committing to one
• Social media content — fill a content calendar from a single prompt
• Concept boards — explore styles and moodboards in batches
• Product mockups — variations on angles, colors, and scenes without repeating yourself

Models & API

GridBulk runs on top-tier image generation models, including Nana-Banana-Pro and GPT Image 2. Prefer code over clicks? Create an API key in the dashboard and generate programmatically — same layouts, same one-credit-per-generation pricing.

Open source

GridBulk is open source. Read the code, open issues, or self-host it yourself:

• GitHub Repository — view source and submit issues
• Documentation — setup guides, API reference, and deployment

Have fun generating.
