I've found that ChatGPT is very good at fine grained generation - you can get it to rewrite sentences and paragraphs with some examples and a general statement of style and it can produce extremely high quality output. Likewise, it can produce very high quality output when given a summary and asked to expand it into a short article, particularly when given areas to emphasize or things to note as it rewrites the content. The key is to prompt carefully and provide concrete examples in addition to referencing the style you want. That combined with keeping the bot on a fairly short leash can produce fantastic writing, you just need to inject the wit and unusually clever ideas yourself.
