Interestingly, it can change pages with tons of text on them without any problem, but cannot seem to do translation, if I ask it to translate a French comic page, the text ends up garbled (even though it can perfectly read and translate the text by itself).
I tried with another page, and it copypasted the same character (in different poses!) all over the panels. Absolutely uncanny!
However when I asked to remake a Western comic book in a manga style (provided a very similar manga page to the comic one), it totally failed.
Also about 50% of the time, it just tells me it'll generate the image but doesn't actually do it - not sure what's going on but a retry fixes it, but it's annoying.
