Technology The architecture

How TheoAI is composed.

Four layers, one model. The customer-facing Operating System at the top is what a scholar interacts with; beneath it the Digital Employee, the Eve-Theology™ Fusion v5 compound reasoner, and the Substrate that grounds everything. Numbered OSI-style — the foundation is Layer 01, ascending to the product at Layer 04.

The architecture Substrate → OS

The signal flows up; the foundation holds it down.

Layer 04
Operating Systems

TheoAI™ — Agentic Theology OS

The customer-facing product. Theo, Majlis, and Mizan surface evidence-grounded Islamic reasoning to scholars, students, and institutions.

Layer 03
Digital Employees

Theo — the theologian

The agent with agency — persistent identity, continuous learning, vector memory. Theo reasons; the scholar decides.

Layer 02
Compound Reasoning Models

Eve-Theology™ Fusion v5 · F5/reasoner

Five cooperating models: a Phi-3 classifier, the Phi-4-derived F5/reasoner (LoRA fine-tuned on Eve-Genesis™ Uṣūl Edition), and three frontier models as consultants, composed best-fit per request.

Layer 01
The Substrate

Eve-Grid™ · Eve-Genesis™ · Eve

The foundation. Eve-Grid™ on Microsoft Azure hosts the fabric; Eve-Genesis™ (Uṣūl Edition) is the 100%-synthetic training corpus; Eve is the meta-orchestrator.

A request descends from the Operating System a customer touches to the Substrate that grounds it. The answer ascends back. One model, four layers.
We don’t compete with frontier labs on foundation-model capability. We compose frontier models into our reasoning systems. Eve-Genesis™ training data is 100% synthetic by construction — no customer conversation is ever used to train a model.
