AWS and DeepLearning.ai's hands-on course on building with LLMs — covering transformer architecture, pre-training, fine-tuning, RLHF, and deploying generative AI applications at scale.

A 3.5-hour end-to-end walkthrough of how large language models like ChatGPT are actually built — from tokenization and pretraining through supervised fine-tuning and RLHF. Karpathy explains everything in plain engineer-to-engineer language with no hype.
