You mean the way it phrases things or constructs sentences and paragraphs, or the way it seems to connect (what we recognize as) ideas?
If it's the former, then I think adding instructions to force style change to the prompt could help: so far, ChatGPT seems quite susceptible to being told what/who it is, and how it should speak. Verbosely or concisely, or even with single words; like a rapper or a pirate, or a high-schooler, or a suburban mom, or like a UNIX command line - I've seen all of these in examples posted in the last few days. Doing this is really as easy as saying e.g. "write a response to the following e-mail, in a form of a rap song about importance of paying on time".
