Lesson 1 of 7
They're all the same shape
6 min read
ChatGPT, Claude, Gemini, Copilot — the logos look like rival superpowers. So why do they all feel oddly similar the moment you start typing?
One box, one kind of engine
Open any of them and you meet the same thing: a chat box wired to a next-word predictor — a model trained to guess what comes next, one word at a time. Different company, different name, same basic engine. None of them is magic; none is a mind. They're variations on one idea.
There's no secret different kind of AI hiding behind a competitor's logo. They sit on the same few dials — the settings just land in different places.
So what actually differs?
Three real things separate them. Tier & speed: a light model answers in a blink, a heavy one thinks longer. Tools: some can search the web, run code, or see images; some can't. Personality: each is tuned to a slightly different default tone. That's the honest list — not magic, just settings and training.
Judge an AI by its tier, its tools, and its manners — not its marketing. Those are the parts you'll actually feel.
Every lab leapfrogs the others every few months, so 'the best one' keeps changing hands. Don't pledge loyalty to a logo — learn the shape, and you can pick fresh each time.
The shape of it
- —Every chat AI is a next-word predictor behind a chat box — the same basic engine.
- —What differs is tier & speed, tools, and personality — not some secret magic.
- —Because they leapfrog constantly, learn the shape rather than marrying a brand.
A friend swears their favourite AI is 'a totally different kind of technology' from the rest. What's the fair reply?
