What Pretraining, Post-Training, and Fine-Tuning Actually Mean

Every time a new AI model is released, you hear the same three terms: pretraining, post-training, and fine-tuning. But what do they actually mean? In this video, I break down all three stages in simple No math. Just a clear explanation of how AI models are trained, step by step. You’ll learn: 1) What happens during pretraining and why it’s so expensive 2) How post-training teaches models to follow instructions and behave safely 3) How fine-tuning turns a general model into a domain expert If you work with AI, use LLMs, or just want to understand what’s really going on under the hood, this video is for you.
