I think Nano banana pro’s answer to the giraffe edit is far superior to the Seedream response, but you passed Seedream and failed NB pro.

Maybe that one is just not a good test?

If you look closely, the NBP giraffe has a gaping hole in it's neck.

I agree, it seems like Seedream has the neck at same length as Nano Banana but also made the giraffe crouch down, making a major modification to the overall picture.
