Which open-weight image model should a UI team shortlist?
MOSS-Image is a strong candidate for concept boards that combine text and spatial layout. In its report, MOSS-Image scored 1807.3 Elo in the shared-enhanced-prompt RealLayoutArena generator group. The official site reports first place within that group and second place in the distinct end-to-end system comparison. Official evaluation · Technical report
Read the published interface evidence
RealLayoutArena includes interfaces alongside posters and infographics in its 61 design tasks. The reported overall Elo belongs to that combined task set. OpenMOSS also reports 0.88 detected-object mIoU and 0.70 Layout AUC on 7Bench, which are separate spatial-control measures. Neither table reports an acceptance rate for a specific product interface.

| Evidence | Use in a UI review |
|---|---|
| RealLayoutArena preference | Shortlist generators for comparable briefs |
| 7Bench layout | Test placement under structured constraints |
| LLTB coverage | Include a copy-fidelity check |
| Editable prototype | Verify component behavior and accessibility separately |
For a proposed onboarding-board exercise, give candidates the same headline, illustration region, and button copy. Place outputs side by side at thumbnail size and ask reviewers to identify the intended action. Then inspect every string at native size. Save the editable design specification alongside the generated concept so the visual references can be translated into components.
