## Writing

- [Your model doesn't need to write the answer. It needs to point at it.](https://smiit.in/writing/answer-is-in-the-input/) (17 oct 2026): For classify and extract jobs the answer is already in your input. Why pointing beats writing, what ScaleDown's CDMs do with that idea, and where it stops working.
- [Your AI coding session gets pricier with every message. Here's why.](https://smiit.in/writing/long-session-cost/) (03 oct 2026): How attention works, why it is quadratic, and what that does to your AI coding bill. Includes a simulator to find where your own sessions go wrong.
- [How UUIDv7 fixes the primary-key tradeoff](https://smiit.in/writing/uuid-v7/) (26 sept 2026): Auto-increment is cheap until you have two writers, and random UUIDs wreck your index. UUIDv7 puts the clock first and stops making you pick.
- [Jev: the AI that doesn't talk (and why that's the point)](https://smiit.in/writing/jev/) (19 sept 2026): Most models want to write you an essay. Jev answers with a number, fast and for a fraction of a cent.
