Denovarix AI 4B

The model behind Nova, the assistant in DNX OS: it decides which tool to use and reads business documents.

One of Denovarix's own AI models, trained by Denovarix for DNX OS.

Denovarix AI 4B is the main model in DNX OS. It does two jobs:

Tool decisions. Given a request such as "email Priya that the pilot starts Monday", it chooses the right tool and fills in its details, or answers directly, or asks for the detail that is missing. Anything that changes something is shown to the person for approval before it runs.
Business documents. It reads invoices and similar documents, including Indian ones: GSTIN, invoice number, date, totals and vendor, in English, Hindi and Bengali.

It runs on the computer's own processor. No graphics card and no cloud service are needed, so questions and files stay on the machine.


Size	4 billion parameters
Runs on	An office PC's CPU, through llama.cpp
Languages	English, Hindi, Bengali
Trained on	Tool-decision cases generated from DNX OS's own tools, and synthetic Indian business documents
