Nanobanana Pro suddenly downgraded? AI Pro and paid API both producing old-model, low-quality images

Today, in my AI Pro subscription, after generating 20 Nanobanana Pro images, it switched to some old model without any warning, producing terrible results. Since I needed to keep working, I subscribed to the API key and tried continuing the work in AI Studio — and there I got the same low-quality output. Something is seriously wrong. I’m getting images from the paid API that look like the old model in Gemini.

The first one was generated right before the limit using Banana Pro — it correctly combined the requested items into one image.
The paid API produced the second image with the exact same input.

Hi @ZsoltQ ,

Apologies for the delayed response, and thank you for reaching out to us. Could you please first ensure a clean setup by starting a fresh session, requesting a new API key, creating a new AI Studio project, and clearing any cached conversation context? Please let us know if the issue persists after completing these steps.

Thanks.
