How MX4 AI studies and builds systems: methods, not a product.
Approaches
Four practical questions: does the system work in the task’s languages, can its answers be traced, where does it run, where does its data come from?

General benchmarks rarely reflect the languages of a real workflow. We treat Modern Standard Arabic, its dialects, French and English, and switching between them, as separate test conditions, together with the terminology of the domain.
Proposed method
Test questions per language · Code-switching cases · Domain terminology · Review by people who speak the language
An answer is only as useful as the passage behind it. Answers should be tied to the passages that support them, citations checked against what those passages actually say, and a missing answer stated as such: “not in the document”.
Proposed method
Passage-level citations · Citation checks · Explicit “not in the document”
Open-weight models can run inside an environment the institution controls, including constrained or isolated ones. Model choice follows the task, the languages, the licence and the hardware actually available.
Proposed method
Open-weight models · On premises or private cloud · Isolated operation
Evaluation and adaptation depend on language data whose origin and permitted use are known. Provenance, rights, versions and access rules should be documented alongside the data itself.
Proposed method
Documented provenance · Usage rights · Versioning
Constraints
An open-weight model alone does not make a system sovereign.
Read our technical notesEvaluate open-weight or approved private models against the task, language, licence and available hardware. Workflows in Arabic, its dialects, French and English need their own evaluation.
Specify where data is stored and processed, which services can communicate, and whether external endpoints are permitted. An isolated environment requires a different design from a connected one.
Define access administration, logging, updates and recovery procedures with the team responsible for running the system. Document the configuration and its dependencies.
