Hi everyone, has anyone else noticed a dramatic drop in Nano Banana Pro API quality over the past couple of weeks?

Lately the results have become significantly worse. The model often fails to follow the prompt properly, and in some cases it simply returns an image that is almost identical to the input, with little to no meaningful transformation.

Honestly, the output quality now feels closer to what we were seeing from image models back in 2023, rather than a current-generation tool.

Yes, absolutely. Over the past few days, it has become even worse. It almost feels like the model is deliberately doing the opposite of what you ask and making each result more terrible than the previous one.
