Walid Saba, senior research scientist at the Institute for Experiential AI, presented his Expeditions in Experiential AI seminar titled "Large Language Models and ChatGPT: What They Are and What They Are Not" on Wednesday, April 10, 2024 at Northeastern University's Curry Student Center (room 333) and online.

Abstract

Large language models (LLMs) and chatbots built on top of these models (e.g., ChatGPT) are now all the rage and have triggered the discussion of many serious issues in all aspects of our society from education to business and government. But what is at the heart of these new developments, and what do they represent? Is human-level artificial general intelligence (AGI) finally here? If not, how close do LLMs and systems like ChatGPT are to AGI? Saba discussed these issues at a very basic level, addressing in the process issues such as bias and toxicity in LLMs, and what is now commonly referred to as “hallucination”. He briefly discussed how such technologies can be effectively used in a number of applications, sifted through the hype and also discussed the limitations of LLMs and what it might take to get us closer to AGI.
