Someone recently wrote to me in the comments that the promt I posted doesn't work in Nano Banana.
I went to check it myself, I always test promts multiple times anyway, but I thought I'd see if anything had been updated.
No, it's working.
Turns out, the person was using Nano Banana through a Telegram bot, not through AI Studio or the Gemini app. As you can imagine, the problem wasn't the promt., and the bot itself - there's a good chance it's not a real Nano Banana under the hood at all.
And judging by the number of bots like this, it may be a frequent story.
Therefore, the question: make a guide on how to use Nano Banana officially - without third-party bots and middlemen?
