I can't replicate this.

I tested your prompt verbatim in the OpenAI playground. Model set to gpt-4-0314, maximum length set to 6485 (nothing special about this number, I just dragged the slider to something high-ish), all other settings left at their default.

I cancelled the request when it reached "one thousand one hundred twenty-one" (which took over five minutes), but up until that point it did not take any shortcuts. I haven't meticulously checked every number, but it printed exactly 1,121 lines, and a cmd+F for "..." doesn't return anything.
