Let's be honest — a lot of people interact with AI tools like they're magic. You type something, it gives you answers, and you move on. But once I slowed down and started looking under the hood, I realised: AI isn't smart. It's just really, really good at guessing.
So what exactly is it doing?
When you ask a question, the AI doesn't "know" the answer. It simply predicts what the next token should be. These models are calculating probabilities: "What's the next most likely token based on everything I've seen in training?"
Why does this matter?
Because once you understand it's just playing a giant guessing game — your prompts get sharper. You stop asking vague questions and start giving it structure, constraints, context. You work with the machine, not against it.
Token limits
Every AI model has a limit to how much it can "hold in mind" at once. It's like a whiteboard that can only fit so much text before it starts forgetting what was earlier. If you've ever asked ChatGPT something and it suddenly forgets what you said 10 minutes ago… now you know why.
Less like a brain. More like a probability engine with a really powerful memory (that sometimes forgets).
