What are some ways to make ChatGPT's responses sound more human?

So, we had this big discussion here recently about how well we can spot AI-generated text, even just after a year. But some of you were saying it’s not just about the AI, it’s also about how the person sets up the prompt. They were saying you can actually tweak these language models to make their output seem totally human.

I’m curious, if any of you are using other language models, what techniques have you found that really work to make the text sound more human?
