Having trouble getting transparent backgrounds in ChatGPT images

I did a little easy test in ChatGPT and gen actually did surprised me a bit with the steps to transparent background. And this time fairly easy. At the beginning I prompted “ fox cub trying to reach for a butterfly, orange background ”, then the rest of the steps can be seen in screenshots​

Usually when I’ve tested with opaque color and then edited to true alpha channel, it results in almost transparent background. But this time, chessboard and then with a simple prompt “ remove the chessboard background ” and the output was completely transparent.

Now, I know this seems like a child who had done the whole testing, but nevertheless, this was a bit interesting.
