A DataCamp course explaining the machinery behind ChatGPT-style systems without requiring you to code. It walks through how LLMs are trained, the transformer architecture that powers them, core NLP ideas, and their limitations. A solid conceptual bridge for people who want to understand LLMs more deeply than a surface primer, minus the maths and code.
Good for: Understanding how LLMs work, conceptually and without code.
Less suitable if: You want to build LLM apps or want the full maths.
