Note: This 2023 video explains foundational AI mechanics using GPT-3/3.5. The principles remain relevant, but the technology has evolved. We recommend watching this video for its conceptual grounding and then exploring the AI Glossary and other AI Hub resources for current information.

This video traces the evolution of ChatGPT from its predecessors, GPT-3 and GPT-3.5. It demystifies the complex mathematical and neural network foundations that enable the model to predict and generate text based on vast amounts of data sourced from the internet. You’ll gain insights into:

  • The foundational “predict the next word” mechanism that powers GPT models.
  • The vast training datasets and the role of deep neural networks.
  • The emergence of unexpected capabilities as the model evolved.
  • The challenges faced, from generating nonsensical to biased outputs, and the steps taken to mitigate them.
  • The transition from GPT-3.5 to ChatGPT, emphasizing its conversational prowess.

Watch the video for a detailed walkthrough of ChatGPT’s journey and its capabilities.

While AI models like ChatGPT are powerful, they are not infallible. By understanding their workings, strengths, and limitations, we can better integrate them into our teaching methods, ensuring a rich and informed learning experience for students at MIT Sloan.
