# Research: AI

We study what AI costs a business, which model does which work, and what a business gains by choosing.

## What we ask

- What a business pays for AI, and for what.
- Which kinds of work need the strongest model, and which do not.
- What staying on one tool, one model or one supplier costs.

## What we do with it

Each finding is set against the product. Where SalexHub already answers it, the piece links to the use case that shows how. Where it does not, the piece says so.

## Research in this area

01 piece, newest first.

- 13 November 2026 · Review: [Cheaper only if you choose](https://salexhub.com/research/cheaper-only-if-you-choose.md). 38 published sources, read for what a business overpays when one model does all its AI work: the lightest model lists at a hundredth of the strongest, spending moved to the top tier, and the tested gain from choosing is real and smaller than its headlines.
