3.5 has, or had, a particular style. No matter what the story, it had a cheerily up-beat ending. The invading aliens learned the errors of their ways and then everyone celebrated. Dracula, Winnie-the-Pooh, and Sherlock teamed up to fight crime.

4 is somewhat more interesting, and I've seen worse from actual humans, but… roll a d6, and on a 1-5 it's terrible, roll a 6 and you get something that's 90% fantastic and 10% just a bit off. For example, this story: https://github.com/BenWheatley/Fiction/blob/main/The%20Silen...

I like it, but if I really examine the thing, the details don't quite line up right. The humans were supposedly primitive, yet "[t]heir cruisers absorbed salvos that would've shattered lesser vessels"?

And sure, there are a million oddities like this in "proper" fiction[0]; but this… still feels like Stable Diffusion in text form. It's cool, it's a technological marvel, it's still, ineffably, not quite right.

[0] Even ignoring that the top speed in the pilot episode should've gotten them home in 7 years rather than 70, Voyager had a bajillion ways to get home sooner — for example, putting the crew in stasis so they didn't age, going at a normal speed, and then using any of the time machines Starfleet keeps tripping over.
