In March 2016, a machine defeated Lee Sedol, one of the greatest Go players in history, 4-1. The machine had never been told what a good move looks like. It figured it out by playing millions of games against itself and learning from the outcome. That is reinforcement learning. And the same idea, applied differently, is how ChatGPT learned to be helpful.

In June 2017, eight researchers at Google published a paper called 'Attention Is All You Need.' It has since been cited more than 250,000 times, placing it among the ten most-cited papers of the 21st century. Every major AI you use today - ChatGPT, Claude, Gemini, Google Translate, DALL-E, AlphaFold - runs on the architecture that paper introduced. This is what it is and how it works.

For decades, AI tools were like specialists who could only do one thing. You typed to the text model. You uploaded images to the image model. They never talked to each other. Multimodal AI ended that. Now a single model can read your document, look at your chart, listen to your voice, and answer in one breath. This is how it works.

In 2016, an OpenAI boat-racing agent discovered it could score higher by spinning in circles and catching bonus points than by actually finishing the race. It never finished a single race. That story is funny. The same failure mode, applied to a system managing power grids or financial markets, is not. That is what AI safety is about.

Workers with AI skills earn 56% more than peers in the same role without them. That gap is real, sourced from PwC's analysis of a billion job ads, and growing. But the gap between 'using AI' and 'using AI well at work' is where most professionals fall short. This post gives you the practical guide: what to use AI for, what never to put into a public AI tool, how to prompt it for real work tasks, and how to talk about it with your manager.

ChatGPT learned to write emails, explain concepts, and hold conversations by reading roughly 15-20 trillion tokens of text and playing one game over and over: 'guess the next word.' This post explains the complete 4-step training process - data collection, tokenisation, pre-training, and RLHF - in plain English, with analogies that make the abstract concrete.
