There's a lot of irrelevant stuff in that answer. People often dismiss ChatGPT based on the free 3.5, not realizing that the paid GPT-4 is in a different league. The difference is a lot bigger than suggested by the 0.5 version number increment. Here's a GPT-4 answer:

If you're focused on writing, then you should consider Ulysses or Scrivener. Ulysses offers a streamlined, distraction-free environment that's perfect for writers who want a no-fuss solution. Scrivener is the go-to for those engaged in long-form writing projects like novels or academic papers, thanks to its robust organizational features. If you're a Markdown fan, go for iA Writer. It's clean, offers excellent Markdown support, and is quite speedy. For coders who write, Visual Studio Code isn't just for programming; it's highly customizable and has extensions that can aid in writing prose. Choose based on your specific needs.

I use the free version and your example shows a vast improvement, indeed. 3.5 looks like a summary of Google results, while 4 actually gives a relevant answer. I don't have much insight into the differences between these versions, assumed that the biggest difference is "just" the training corpus.

It's also a much larger model which is slower and more expensive to run, which is why they can't offer it for free. The improvement is not always obvious at first glance but it is massive. I assume they will eventually be able to distill it into a smaller model that they can offer for free. I'm actually surprised that hasn't happened yet, especially given the fast progress in shrinking open source models.
