AI-generated content tends to be statistically predictable, with each word selected based on the ones that came before it. As a result, these language models produce writing that is fluent, grammatically correct, and coherent. However, it often lacks the unpredictability and originality that characterize human writing.

In contrast, AI-generated writing often lacks this diversity, especially across longer pieces of content. Our post on How to Tell If Something Was Written by AI breaks down the key signals in detail.
