Title: Critical Inconsistency: Gemini 3 Pro Image (Nano Banana Pro) Editing Performance Disparity (Web UI vs. API)

Hi! This is exactly something I’m seeing with gemini-2.5-flash-image. Very consistent and better quality results in Google AI Studio vs what I get through API (with same input data in a form of an image and a prompt). Setting generationConfig same as what we can set in Google AI Studio doesn’t make a lot of change. This definitely looks like something is happening behind the scenes. And I get it - we don’t need to know every Google secret. What I don’t get is that AI Studio is being advertised as a playground for devs to test models before implementing them through API. But without this consistency - this does not make sense.
