AI vs Machine Learning vs Neural Networks vs LLMs: What's the Difference?

6 June 2026 · Sulabh Sethi

A plain-English guide to how AI, machine learning, neural networks, and large language models actually relate. They're not competing ideas — they're nested inside each other. Written by an ex-Army officer who now builds them.
