Infographic cut off at bottom

I prompted chat gpt 4o to generate an infographic from my text input. It did a great job, except at the bottom of the image there was more generated, but it was cut off mid sentence and partial illustration. It looked as if the image size was constrained to a certain size, so when the content reached the bottom, it stopped generating mid sentence. I wrote this prompt “unfortunately, the bottom of the infographic you created is incomplete as the bottom portion is missing in the illustration you created. please try again and complete the infographic” I tried this twice to no avail. Is this a bug? Please help me understand how to produce a complete infographic.

That is a known symptom, discussed in the model card, cropping. It has attention, if not a solution found in the year of development. Suppose they could give more extended portrait aspect image length that keeps on going, but then that entailment would frame others incorrectly.

You can try to ask it to zoom out the image and expand the content, sometimes it work.
If not, you can edit and mark the parts that went wrong and tell it how to complete it correctly.
