Open the original- What it measures
- The comparison separates the sentences that came from the model from the sentences the participant wrote, in essays written with InstructGPT.
- What it does not show
- The finding concerns argumentative essays written with a 2023 model. It shows where the sameness came from in that study, not how much a cleanup pass changes a dictated draft.
