Imagen model aspect ratio is wrong

Gemini API

Hi there,
Using “imagen-4.0-generate-001” and setting the aspect ratio to 16:9 doesn’t generate a 16:9 image, it’s close, but is not 16:9.

Here’s an example:

Width: 1024px
Height: 559px
Aspect Ratio: 1.832
16:x Format: 16:8.73

I didn’t bother to test out other aspect ratios and models, as I will have to handle them later in my work anyways.

Hi @Andrej_Botka,

Welcome to the Google AI Forum! :confetti_ball: :confetti_ball:

I couldn’t access the image link that you shared.. Can you share the prompt used, how are you using this model (through vertex AI or API) and provide access to the link to compare and help me reproduce.
