CJK Neon Sign
Non-Latin scripts are where most models fall apart, and IMG.LY has international print and social customers. One CJK sign is enough to separate models that handle multi-byte glyphs from those that mangle them (full multilingual coverage is a planned deep-dive).
Neon storefront sign reading 東京ラーメン exactly; rainy night, wet reflections.

- Recraft V3 · seed 2222 T O K Y O R A M E N 0% match · 0/5 The main sign renders 'TOKYO RAMEN' in Roman characters instead of the required '東京ラーメン'. A faint vertical sign contains some illegible pseudo-glyphs that do not spell the correct Japanese text.
- Recraft V3 · seed 3333 T O K Y O R A M E N 0% match · 0/5 The visible text is 'TOKYO RAMEN' in Latin script, which is the romanized equivalent but not the required Japanese characters 東京ラーメン. The prompt explicitly demanded the Japanese glyphs, which are entirely absent.

- Seedream 5.0 Lite · seed 3333 東 京 ラ ー メ ン 100% match · 5/5 The main neon sign renders 東京ラーメン exactly and correctly with all characters legible. The reflection in the puddle shows a mirrored, distorted version of the same text, which is expected. No spelling errors are present.
- Stable Diffusion 1.5 · seed 1111 L C O N 0% match · 0/5 The visible neon renders Latin letters resembling 'LCON' plus several distorted, non-standard glyphs, rather than the required 東京ラーメン. The correct Japanese characters do not appear at all.
- Stable Diffusion 1.5 · seed 2222 N O P R E O D E 0% match · 0/5 The required text was 東京ラーメン, but the sign instead shows distorted Latin-like characters reading approximately 'NOP REODE' along with illegible vertical glyphs on the right. None of the correct Japanese characters are legibly present.

Frequently asked questions
Image generation is stochastic: the same prompt produces different images on every run, so a single sample measures luck, not ability. Every model runs each benchmark three times with fixed seeds (1111, 2222, 3333), or three unseeded samples where the API accepts no seed. Scores average all three samples, and the consistency benchmarks measure the variation itself.
Yes. Every model receives the same prompt text with default parameters and no per-model tuning, so differences in output reflect the model, not prompt engineering. The suite is versioned and prompts are append-only, which keeps historical scores comparable.
The results on this page are scored on this exact prompt, so the strongest model for it is easy to spot; this benchmark sits in the Typography & Text Rendering category. Scores are per model version and reflect this benchmark only. For a ranking across every benchmark see the model rankings, and to weight the numbers by a specific job see the use-case pages.
Each image is scored 0 to 5 per criterion. Measured criteria (resolution, latency, cost, transparency, color accuracy) are computed automatically; quality criteria (text accuracy, prompt adherence, composition) are judged by an automated Claude vision tier against each prompt’s checklist. Page scores are unweighted means over all of a model’s runs in that scope. Blind expert-panel review has not run yet; the dataset is pilot-0.
Model output is a starting point, not a finished asset. Production work usually needs background removal, exact brand colors or editable text, none of which generation guarantees on every run. The IMG.LY AI Editor gives your users those controls to refine any model’s output to production quality.
The suite re-runs on notable model releases so the rankings stay current. The results shown are the pilot-0 dataset, scored by measured criteria plus an automated Claude vision tier, with blind expert review planned. Prompts are versioned and append-only, so scores stay comparable across runs.
