**MatrAIx** is a population-scale, persona-driven infrastructure for evaluating
AI systems and interactive products with heterogeneous simulated users. Instead
of testing against a generic or interchangeable user, MatrAIx instantiates
sampled persona records as LLM agents and runs them through reproducible tasks
across four environments — **Survey**, **AI Chatbot**, **Web**, and **App**
(native desktop and mobile, including macOS and iOS).
At its foundation is a shared schema of **1,290 categorical dimensions** covering
background, psychology, capability, and behavior. Personas combine
dependency-aware synthetic generation with evidence-aware human grounding; a
deterministic, quality-filtered coreset of **one million personas** is released
for research on
Hugging Face.
Shared telemetry, task-owned verification, and reporting connect individual
responses and trajectories to subgroup- and population-level findings.
The name nods to *The Matrix*: a simulated world useful for exploration, stress
testing, and hypothesis generation, **not a replacement for evidence from real
people**.

## Releases
- **[2026-08-04]** Technical report on arXiv: MatrAIx: Simulating the World with 8.3 Billion Persona Agents (`2608.04205`).
- **[2026-08-01]** Released Persona 1M on Hugging Face (~1M quality-filtered personas).
- **[2026-07-31]** Open-sourced the Playground and task library: MatrAIx-Persona-8B.
- **[2026-07-29]** Position note: From Personas to Simulated Users.
## Requirements
- Docker — needed for Web and OS-app tasks
- uv and Python 3.12
- Node.js 20+ (Playground / viewer frontends only)
- Model API keys for real persona runs — see agents.md
 (the install checks below do not need a key)
> **Windows users**: run everything inside
> WSL2 — open PowerShell,
> run `wsl --install` (installs Ubuntu), then clone this repo **inside the WSL
> filesystem** (e.g. `~/MatrAIx`, not `/mnt/c/…`, which is much slower) and
> enable *WSL integration* in Docker Desktop → Settings → Resources. Every
> command in this README then works exactly as written. Native
> PowerShell/cmd is not supported (the task verifiers require `bash`).
## Installation
 [code] 
Run jobs with **`uv run matraix run …`**. After install, use the
