ChatGPT is the most popular AI in the world, but how does it work? In this 5 minute video, we'll build a simple version of ChatGPT in under 40 lines of Python code to better understand it! Our version of ChatGPT will be called ElonGPT, trained to act just like Elon Musk, so that I can ask him if he will give me a free ride to Mars! ChatGPT was built in 3 steps, generative pre-training to learn English, supervised fine-tuning to learn dialogue, and reinforcement learning from human feedback to improve its dialogue capability. We'll go through each, step by step. The code that i use in the video is below!
