Multilingual evaluation
Testing in Arabic, its dialects and French, with code-switching and institutional terminology.
Company updateMX4 AI is part of NVIDIA Inception
Sovereign AI for a multilingual region.
MX4 AI is an AI startup focused on the MENA region. We build and openly study AI that understands Arabic, its dialects and French, shows the evidence behind its answers, and is designed to stay under the control of the organization that deploys it.
Open research · Question 01
Our first question
Does an AI document reader keep the same evidence when the same question is asked in French, Modern Standard Arabic or Moroccan Darija?
The question is what changes when only the language of the question changes. Moroccan Darija is the first dialect we study.
Illustrative values, not results
Each dot is a passage, placed by meaning in a 2D projection: closer means more similar.
When we publish, we publish the data, code, results and limits together.
This is a research question, not a published result.
Technical notes
Engineering perspectives, not experimental studies.
Technology
The approaches behind our work.
Each dot is a passage, placed by meaning in a 2D projection: closer means more similar. The dashed ring marks the 0.70 threshold.
Evidence-grounded retrieval
Answers tied to their supporting passages, or an explicit “not in the document”.
Private inference
Open-weight models designed to run in environments the institution controls.
Governed language data
Language data with documented provenance and usage rights.
Use cases · Illustration
Where AI can help, and where people decide.
Referenced answers
The AI prepares a sourced answer; your teams choose the sources and verify it before use.
Document review
The AI flags discrepancies with references; a reviewer decides if the file is complete.
Human-approved assistance
The AI drafts; an authorized person checks and approves anything sent.
Illustrative scenarios, fictional content, not customer case studies.

What is MX4 AI?
An AI technology startup focused on the MENA region, studying and building sovereign AI for Arabic, its dialects and French, grounded in evidence and designed to stay under the deploying organization’s control.
What does open research mean at MX4?
When we publish, we publish the data, code, results and limits together. Our notes are engineering perspectives, not experimental studies; questions we study are not presented as results.
Are the examples on this page live AI?
No. They are illustrations: a fictional corpus and document, prewritten questions and answers. No AI model runs on this website.
Can we work with MX4?
Yes, selectively, where our research applies. Describe your context through the contact form.
Where can systems run?
Systems can be designed for on-premises, private-cloud, hybrid or isolated environments, depending on the institution’s security, connectivity, data-residency and operational requirements.
How do you approach Arabic and its dialects?
As a whole-system question, not an interface setting: Modern Standard Arabic, its dialects, French and code-switching affect retrieval, terminology, citations and when to refuse or defer to a person. Each needs its own evaluation, with people who speak it.
