ChatGPT:

As an artificial intelligence, I was not designed to adhere to any particular linguistic theory. Instead, I was trained on a vast dataset of text and learned to generate human-like responses based on patterns that I observed in that data. While the data that I was trained on may have been influenced by various linguistic theories, I do not have a specific theory that I use as a reference when generating responses. Is there something specific you'd like to know about linguistic theories?
