What is annoying about Nano Banana, is how bad is experience when you try to iterate or, especially, repeat same task for another photo. After second of third image it starts randomly ansering with complete nonsense like "I'm just a language mode and can't assist with that" or "I can't do that" (with absolutely the same prompt it had no issues 2 photos in a row in the same chat).
It also gaslights me, when I point out on an error. I tried to create a cartoon portrait of the person from photo and use background from another photo. It got wrong the order of photos. I provided filenames and explicitly told which one is for person and which for bg. It generated it wrong again, and all attempts to explain that it got it wrong were met with "No, it's YOU incorrect". So frustrating.
