Translate Gemma Image: OCR translation in 6 screenshot tests
Translate Gemma Image tries to translate straight from an image: no separate OCR step, no copy/paste. This post tests how it handles common UI screenshots: carts, warnings, OTP messages, and appointments.
Six synthetic screenshot images were created (one per language). Each model received the same instruction: translate the screenshot content into English while keeping numbers and symbols intact (prices, serial numbers, OTP placeholders).
Languages tested: Turkish, German, French, Spanish, Polish, Dutch.

Results: 6 screenshot tests
Test 1 (Turkish cart summary)
Input screenshot (Turkish).
Model
Output (English)
4B Image
Shopping total: 1,249.90 TL
Shipping cost: 79.90 TL
Delivery: 2-3 business days
Note: Do not leave it at the cashier
12B Image
Cart total: 1.249,90 TL
Shipping cost: 79,90 TL

27B Image
Cart total: 1,249.90 TL
Shipping fee: 79.90 TL
Delivery: 2-3 business days
Note: Do not leave it with the doorman.
Quick take: the hard part here is not translation, it is reading short notes correctly. One output changed the meaning (cashier vs doorman).

Input screenshot (German).

Test 5 (Polish OTP message)
Input screenshot (Polish).
Model
Output (English)
4B Image
Your password is valid for 15 minutes.
Do not use this code: {OTP}
12B Image
Your password will expire in 15 minutes.
Do not share this code: {OTP}.
27B Image
Your password will expire in 15 minutes.
Do not share this code: {OTP}.
Quick take: meaning drift shows up fast on security UI. A single verb swap (use vs share) changes intent.

Input screenshot (Dutch).

Takeaways
These models can translate from images, but the main failure mode looks like OCR slips (wrong noun, dropped punctuation, changed intent).
When the UI text contains security meaning (OTP rules), small wording shifts matter.
Model size does not only affect quality. Stability under load matters too.
