What is the ‘delves’ style?

There is some circumstantial evidence that the word 'delves' implies that ChatGPT wrote it.

Some evidence here: https://arxiv.org/html/2406.07016v2

>Less common words with strong excess usage included delves (=28.0), showcasing (=10.2) and underscores (=10.9), together with their grammatical inflections (Figure 2a).

But of course, that isn't a smoking gun, it might just be coincidence. The linked arxiv paper itself uses 'delves', probably tongue-in-cheek :)

'delves' is now part of my regular vocabulary because of GPT lol
