Eighteen limits, each one read directly from the constant the generator enforces rather than copied off a model card — and each with the date it last changed. If a number here is wrong, the site is wrong, because this page and the Generate button are reading the same value.

Every value above is read from the code this site runs, not retyped from a model card, and every date is the commit where that value last moved. The two rate rows quote fal's published list price as read on 2026-09-03 — the source is here — with the launch promotion excluded, because a rate card built on a discount expires with it.
