GridBulk is an AI batch image generation tool. It generates a grid image (up to 4×4) from your prompts and automatically splits it into up to 16 individual images — one credit per generation, no matter how many images you get back.

How does grid splitting work?

Pick a layout from 1×1 to 4×4, write one prompt for all cells or a different prompt per cell. The AI generates a single high-resolution grid, then GridBulk splits it pixel-perfect into individual assets you can download separately or as a ZIP.

How many images can I generate at once?

Up to 16 per generation with a 4×4 grid. A 4×4 batch costs the same single credit as a solo image, so your cost per image drops to 1/16.

Is there a free trial?

Yes — your first generation is free. After that you can pay per credit or subscribe; each generation costs one credit regardless of grid size.

Does GridBulk offer an API?

Yes. GridBulk provides a REST API with sync and async batch generation endpoints, authenticated by API key, so you can generate and split grids programmatically.

What is GridBulk

One prompt in, a grid of images out

GridBulk is a batch AI image generation tool with one twist that changes the economics: instead of producing a single image per request, it generates a grid of up to 4×4 images in one pass and splits it pixel-perfect into individual assets. Whether you asked for one image or sixteen, a generation costs one credit.

Three modes cover the common shapes of volume work. Single produces one image. Gacha fills the grid with variations of one prompt, so a concept fans out into many directions at once. Compose assigns one prompt per cell, turning a 3×3 grid into a nine-shot storyboard or a complete product angle sheet from a single submission. Reference images steer style, and results arrive as presigned URLs you can download individually or as a ZIP.

Everything is reachable programmatically. A REST API ships sync and async endpoints for batch jobs, an MCP server lets AI agents drive generation on their own, and the whole contract is published as an OpenAPI spec at /openapi.json. Under the hood GridBulk runs established image models from Google and OpenAI, selected per generation. The dashboard history keeps every generation retrievable, so last week’s keepers stay one search away. Your first generation is free — pick a grid and judge the split quality yourself.

01One credit per grid — grid size is a creative decision, not a cost decision.

02Compare side by side — the contact-sheet view exists because judgment improves when results are seen together.

03Agents are first-class users — the API, MCP server and docs are built for machines as much as for people.

04Prompt recipes included — built-in agent skills teach the AI how to brief a batch, so you are never starting from a blank prompt.

05Independent and self-funded — a small product run on revenue, not on venture timelines.
