# Families of concept designs in one image

> Generate nine options for one brief in a single image, then split them apart

Generating options in one image makes them a family: same scale, light and presentation, so they're easy to compare. Nine options cost one generation.

## How it works

1. **Nine concept models in one image (Nano Banana Pro 4K)** lays out a 3x3 grid for one brief (a small lookout tower), naming a different formal idea for each cell.
2. **Split the grid into nine options** crops each cell into its own image.

## Tips

* Name a distinct idea for every cell, or the options converge.
* Pick a favourite and develop it with [Enhancing a selected concept](https://docs.runchat.com/examples/enhancing-a-concept.md).
