Comparison-first image generation.
parallax//sbs is built around one idea: the interesting part of prompting isn't a single image — it's the comparison. So we make breadth the default and put the diff front and center.
Multi-model, multi-seed
Run every model and several seeds in a single shot. Stop generating one image at a time and tweaking blindly — see the spread at once.
Redline prompt editing
Select text and replace it inline. The old words go red and struck; the new words go green. We keep both versions as a single edit.
Side-by-side comparison
Turn on prompt-edit effects and results split into two columns — old prompt vs new — aligned strictly by the same model and seed per row.
Spend on breadth, not tabs
You pay per generation in credits, not a flat subscription. Put your budget into width — more models, more seeds — instead of juggling browser tabs.
All launch models are seed-capable, which is what makes row-aligned seed comparison possible. Models without a usable seed parameter are intentionally excluded.
