1 · Think first

AI's main job is adding the next word, so it's weak at things you need to know exactly, like big multiplications or today's weather. So people hooked up tools next to it: a calculator, search, running code.

The important part isn't the tools, it's choosing for itself when to grab one. Since 2023, models can say 'I need a calculator now' in a set format, get the result back and finish the answer.

So a good AI isn't one that knows everything. It's one that notices it doesn't know and grabs a tool — the same call you make when you use a calculator on a test.

Starting in 2023, models began saying 'which tool to call, with what values' in a set format — and now that's a basic feature of almost every model.
