Why a Brazilian AI
- Real Portuguese: Iryx's published accuracy numbers were measured on short texts in Portuguese, not translated from an English test.
- Prices in reais: no dollar billing. Plans and overage are in Brazilian reais.
- Brazilian invoice (nota fiscal) and support in Portuguese.
- Priced for Brazil: one of Iryx's principles is frontier technology at a price that fits the Brazilian reality.
What Iryx 1.0 does
Iryx is a decision model. You send a context and closed questions; it returns one typed answer per question, with the confidence and the probability spectrum. It does not write text. See what a decision model is and its use as a text classifier.
On Iryx's own test, in Portuguese, Iryx had the highest accuracy of the 2026-10-19 round: 83.1% (187 of 225 decisions), among 11 decision models measured together. On the questions whose answer could be calculated, it got it exactly right. The median time per case, from Brasília, over the internet, was 310 ms, and 95% of cases finished within 3.2 s. Each request carries up to 32 decisions, and each answer comes with its measured confidence. On the two blind tests from September 2026, on new subjects (100 questions each), it scored 86% and 73%.

What happens to your data
The API is not open to the public yet. What is kept, for how long and why will be in the platform's Privacy Policy, published before the first customer. How the service works: the model server reads the request, decides in memory and replies, and the content does not go into the logs. The access log keeps operational data (date, time, IP, key ID, route, status and duration) for 6 months, as Brazil's Marco Civil da Internet requires.
