Drex v2.0 does not write text. You send a situation as text or a table of data, plus questions of set types, and in a single pass it gives every answer to every question a probability, which fits ticket routing, document sorting and rule checks where your own system reads the number. It is the bigger model that follows Drex v1.5. Both take the same inputs, so moving between them needs no change to your questions.
You pay for what each request uses. No subscription, no minimum.

Nace Ai. Released 12 October 2026.
Drex v1.5 does not write text. You send a situation as text or a table of data, plus questions that are yes or no, multiple choice or a score on an ordered scale, and in one pass it gives every option a probability you can set a cut-off on. That suits routing a ticket, sorting a document or checking a policy where your own system needs a number to act on.
Drex Max reads long stretches of text — about 260 pages at once — and answers typed questions about them: yes or no calls, choices from a set list, or scores on a scale. It is built for sitting down with a document or a situation and getting a firm decision back, not a chat or an essay. It can also write up to 230 pages of output in one go, which few decision models of this kind manage. It does not take in pictures, audio or video, so jobs that need to look at an image or listen to a recording need a different kind of model.
