The Method
Four weighted dimensions. Same 50 prompts for every tool. Three blind reviewers. No sponsored placements — we buy our own subscriptions.
Dimensions
| dimension | weight | measures |
|---|---|---|
| output_quality | 40% | Blind-scored realism, composition, artifact rate |
| prompt_adherence | 25% | Prompts with all constraints rendered correctly |
| editing_control | 20% | Inpaint stability, series consistency, iteration |
| value | 15% | Per-image cost at production volume (quarterly verified) |
Protocol
Default settings, October 2026 test window, prompt set available on request. Final score is the weighted mean:
score = Σ(dim_score × weight) # recompute any score on this site
