Why Multilingual Text-in-Image Is Hard
Rendering legible text inside a generated image was an industry failure mode for years — and it's far harder outside English, where scripts, diacritics, and layout direction trip models up. In 2026 a few models finally do multilingual text-in-image well. If you make localized ads, packaging, posters, or UI mockups in multiple languages, these are the ones. All are on LinkModel under one key.
The Best for Multilingual Text
Nano Banana Pro — highest text accuracy
Google's Nano Banana Pro (Gemini 3 Pro Image) renders ~94% accurate text including long passages and multilingual layouts, with Search grounding for factual context. The strongest single pick when text legibility is the top priority. $0.134/image (1K/2K).
Seedream 5.0 Pro — native text in 14 languages, cheapest
ByteDance's Seedream 5.0 Pro renders native text across 14 languages and excels at dense, structured multilingual layouts — at roughly half Nano Banana Pro's price (~$0.0675–0.135). Especially strong for CJK scripts and layout-heavy commercial design. See the API guide.
GPT Image 2 — reasoning-driven text placement
GPT Image 2 plans text placement before rendering, giving near-perfect results across 10+ languages — great when the layout logic is complex. State the target language explicitly. Prompting guide.
Quick Comparison
| Languages | Text accuracy | ~Cost/image | Edge | |
|---|---|---|---|---|
| Nano Banana Pro | Multilingual | ~94% | $0.134 | Grounding, 4K |
| Seedream 5.0 Pro | 14 native | Strong | ~$0.0675–0.135 | Dense layouts, price |
| GPT Image 2 | 10+ | Near-perfect | ~$0.05–0.21 | Reasoning layouts |
How to Get the Best Multilingual Results
- Quote the exact text in the prompt and name the language/script ("headline in Japanese: …").
- Specify layout — dense multilingual posters benefit from explicit placement.
- Draft cheap, finish precise — iterate on a cheaper tier, render finals on the best text model.
- Verify glyphs — always eyeball non-Latin scripts; even top models occasionally slip on rare characters.
Which to Choose
- Maximum text accuracy / 4K → Nano Banana Pro.
- CJK + dense layouts + lowest cost → Seedream 5.0 Pro.
- Complex reasoning-driven layouts → GPT Image 2.
Because all three share one request shape on LinkModel, you can generate the same multilingual poster on each and pick the cleanest. Full field in best AI image generation APIs; editing in best image editing API.
