Why this site exists

Most AI coverage goes stale within weeks. A model gets an upgrade, a price changes, an exclusive feature ships everywhere, and the article that told you exactly what to buy is quietly wrong.

So we write about the parts that hold: what these systems actually do, the dimensions tools genuinely differ on, and how to test a candidate against your own work in twenty minutes. Where we do publish numbers — API prices, mainly — we keep them in one maintained table, date-stamp it, and link the source so you can check us. That table was last verified on 20 July 2026; you can read it on the model pricing page.
