Inquiry About 9:16 Vertical Image Generation Issues in ChatGPT and DALL·E

I have encountered issues when using the GPT-4-O model in ChatGPT and the DALL· E GPTs for image generation, specifically with the 9:16 vertical format. Despite making various adjustments and modifications to the prompts, the generated images rarely appear in the correct 9:16 vertical ratio. This issue occurs both in the image generation feature of ChatGPT and on the DALL· E platform.

This problem has impacted my experience, so I would like to know if this is a known issue or if there are any recommended solutions that could help me generate images that accurately fit the 9:16 vertical ratio.
For Example:
Beautiful woman,Japanese actress,off shoulder,city background,
looking us and smiling,upper half of the body,incredibly detailed
face,incredibly detailed beautiful eye,focus on face,masterpiece,
high quality,best quality,highly detalled,insanely detailed,4K,9:16
output:

regenerate also is same

why ??? I am very distressed

You fondo answer? Same problem here

The issue was fixed when I tried generating again today; all my images were generated at 9:16. I used to experience this issue too months back. Better still, use Sora; the aspect ratio is there.

You’re right! The issue with DALL-E 3 producing rotated images when requesting portrait/vertical images is not an issue any more with the replacement image generator using gpt-4o technology. Which now uses a different size, now 1024x1536 instead of 1024x1792.

Therefore, to be more precise, images were not generated at 9:16, as one can see from the choices in Sora.
