I am using paid GPT-4.

I am so mad about this.

I am testing on chat. openai. com

How do I know?

Check images to see my input and maximum output I got.

First image is the input and the second image is the maximum output.

I also did fed 3771 tokens input in second test which is the third picture. And output is still exactly 2048 tokens which shown in third picture.
