Describe the bug

The API v1/images/generations do not apply the size. All of the responses is 512x512 for many different input values. I have changed to another model but it is the same.

which models have you tried? note that only SDXL models support more than 512x512.

[thuongvovan]

Thank you for considering my question.
I have tried some models like: stable-diffusion-xl-base, stable-diffusion-v1-5, dreamShaper... I have set the size lower 512x512 for example 256x256, but it still returns a 512x512 image, my expectation in this case is a 256x256 image.
If I have misunderstood something, please forgive me.
I would like to say thank you again for the wonderful product that you made and what good you have contributed for community. It is very helpful for a newbie in AI like me.

I'm testing things here but it looks the size is passed correctly:

Are you sure you are passing the size correctly? can you share your settings/curl calls?

[thuongvovan]

Yes. It is almost like your default. With the call in the image below return 512x512 image in both.
