OpenAI announced a randomized study involving more than 1 000 students. At the center of the work are ChatGPT, training in critical thinking, originality, and the results of completing a real university assignment.

The publication describes the study, but the provided material does not include its results, participant characteristics, or details of the assignment. Therefore, no conclusion can be drawn about whether ChatGPT improved academic outcomes or critical thinking.

The significance of the work lies in attempting to assess ChatGPT's use in education through observable learning outcomes, not only through the quality of answers. The next important signal will be the publication of the full methodology and comparative results of the groups.
