Vague title, but I don’t know how else to describe the issue. First appeared today. I have seen it on both NBP and NB2. Suddenly I’m seeing a number of image generations simply output this: [image] [image] [image] Normal output would look like [image] [image]

Hi all. Sorry for the issues. 2k and 4k resolution should be working again. Please let us know if you still face issues.

Yes, I am facing the same with Gemini API but not seeing it happen with Vertex AI same model.

I have reported this two weeks back to @Mustan_lokhand hope they fix it soon.. Running a production app with gemini api is unreliable… [Screenshot 2026-06-19 at 9.49.59 AM]

Same issue in my case, usually works fine, but today these photos started to appear [telegram-cloud-photo-size-2-5308010001228044935-y]

Same issue, hope it will be solved soon

I am also seeing blurry and distorted images. The colors on those blurred images also don’t look like any of my input image.

Hi all! We’re looking into it, sorry about the disruption.

I have the same issue, outputs are either completely broken, or very low quality. That is Nano Banana Pro via AI Studio, also happens in my Photoshop Plugin for Nano Banana Pro.
