Explaining the “T” behind ChatGPT


Prof. Jiaming Xu

The letter 'T' in ChatGPT represents Transformer, which serves as a fundamental building block for GPT and various other large language models. At its core, the Transformer mechanism aims to emulate the way humans process language, by selectively focusing on different parts of a sentence and their relationships to the other parts. In this discussion, Jiaming Xu, an associate professor of decision sciences, will provide an overview of the architecture underpinning the current wave of AI and discuss some of its possible business applications.
