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.
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.
Live cost preview
See the estimated cost of a sweep before you run it, with per-image pricing for every supported model.
From base prompt to comparison grid
Pick a model
Choose from six models across five vendors. The input form builds itself instantly.
Mark what to sweep
Toggle any input — prompt, guidance, seed, steps — as a swept axis.
Run in parallel
Every cell generates concurrently while you watch the grid fill in.
Compare & decide
Read the labeled grid to see exactly how each parameter shifts the result.
Six models, five vendors
Mix and match across the leading generative image models — all behind one consistent interface.
