6 models · 5 vendors · one labeled grid

Sweep every parameter across image models at once

Pick a model, mark any input as swept, run variations in parallel, and compare results side by side in a labeled grid. Forms build themselves from each model's OpenAPI schema — and Claude expands a base prompt into stylistic variations along any axis you name.

Why Sweep

Stop generating one image at a time

Sweep turns tedious trial-and-error into a single structured experiment — so you can actually see how a parameter changes the output.

Sweep up to two axes

Mark any input as swept — one axis for rows, one for columns — and get a full labeled grid of every combination.

Parallel generation

Every variation fires off concurrently against Replicate, so a whole grid resolves in the time of a single run.

Prompt expansion with Claude

Give a base prompt and a named direction; Claude Sonnet expands it into stylistic variations along that axis.

Schema-driven forms

Every model's input form is generated dynamically from its OpenAPI schema — no hand-written fields, always up to date.

Compare across models

Put different models head-to-head on the same prompt to see how each vendor interprets it.

How it works

From base prompt to comparison grid

1

Pick a model

Choose from six models across five vendors. The input form builds itself instantly.

2

Mark what to sweep

Toggle any input — prompt, guidance, seed, steps — as a swept axis.

3

Run in parallel

Every cell generates concurrently while you watch the grid fill in.

4

Compare & decide

Read the labeled grid to see exactly how each parameter shifts the result.

Supported models

Six models, five vendors

Mix and match across the leading generative image models — all behind one consistent interface.
