Introduction:

The advances of some technologies and the obsolescence of others are marching at an unimaginable speed, especially in this twenty-first century. In the last months of 2022 and first months of 2023, many questions and controversies in different fields have arisen with respect to "Chat GPT", an innovation that presents challenges never thought of before for today's society, as well as new challenges that will have a direct impact on the training and/or performance of professors, students, health professionals, law practitioners, politicians, computer scientists, librarians, scientists and any citizen.

Objective:

To identify some technological characteristics of Chat GPT.

Positioning of the authors:

In news and reports, assessments by specialists are read; virtual meetings and presentations have been held; and several articles and videos on this topic are available, some of them even elaborated by the "assistant" itself.

Due to the novelty of the subject, its recent assimilation as a tool for professional development, as well as the interest shown in recent days by the community of professors of Cuban medical sciences, and considering that this tool is the result of the development of artificial intelligence, it is worth wondering what it consists in and what its prospects are.

Conclusions:

It is appropriate to approach the subject with a focus on the possibilities and challenges that it opens to education and learning.
