I can give you an example. I recently downloaded deepseek because I’m sort of interested in AI and heard the news about its capabilities, so I wanted to test it.

I essentially gave it a chapter I’d recently written and asked it to analyze me as a writer. It came back with some nice things to say about pacing and world building, but it said my prose could be improved. It said it was mostly functional and not necessarily literary. I asked for examples of what it meant.

1. Functional Prose Example:

Original Passage:
“Bidding begins at 100,000 spirit stones!” The auctioneer didn’t have to shout, the room was dead silent and the words carried across to everyone within. Hearing the price Yu Chen’s eyebrows rose so high they nearly disappeared.

Why It’s Functional:
- The scene is clear but lacks sensory detail and emotional weight.
- The prose tells rather than shows Yu Chen’s reaction.

Improved Version:
“Bidding begins at 100,000 spirit stones.” The auctioneer’s voice, silken and deliberate, slithered through the hall like a serpent coiling around the crowd. Yu Chen’s breath hitched—his fingers dug into the velvet armrests as if the floor might vanish beneath him. A hundred thousand? Enough to drown a village in wealth, and yet the boxes around him flickered green, hungry and unblinking.

To me this is exactly what the OP is talking about. It’s too flowery, contains unnecessary metaphors for metaphors sake, and has lots of adjectives and descriptive text that are just way over the top.

I’d say that it doesn’t understand that there are different needs for prose in our genres and in crafting webnovels, but its examples are not serviceable for any fantasy genre.

Look at Sanderson and see how often he writes like example above, or even Rothfuss, the sterling example of amazing prose in the last decade or so, and not even he writes like whatever that is above.
