MAGI: Open-Source AI System for Consumer Hardware

MAGI is an open-source AI system inspired by Neon Genesis Evangelion, designed to run on consumer hardware with full-featured AI assistant capabilities. Key features include: customizable core reasoning protocol, modular toolchain (code execution, web browsing, image generation), long-term memory Codex, multi-agent NERV mode, and Telegram remote operation. Project repo: Kenshiro-28/MAGI. It prioritizes localization, privacy, and user customization over cloud-based services.

Section 02

Background & Design Principles

MAGI's name comes from Neon Genesis Evangelion, aiming to make functional AI assistants accessible on consumer hardware. Unlike cloud-based commercial AI services (e.g., ChatGPT), its core design principles are localization (run on local laptops/desktops), customizability (tailor reasoning protocols and behavior), and modularity (extend via plugins). It supports Debian stable natively and other OS via Docker, ensuring cross-platform use without expensive GPU servers or cloud subscriptions, keeping data private locally.

Core Technical Features & Methods

Customizable Core Protocol

MAGI's Core Protocol allows defining structured reasoning frameworks (default has 5 stages: Foundational Deconstruction → Hypothesis Generation & Inversion → Multi-Method Derivation & Triangulation → Epistemic Rigor Loop → Metacognitive Consolidation). Users can customize to variants like Chain-of-Thought.

Modular Toolchain

Plugins include:

  • Code Runner: Generates/executes Python code in isolated environments (with Ruff check, 30min timeout, 10 rounds of optimization).
  • Web Plugin: Real-time internet access for up-to-date info.
  • Image Generation: Uses SDXL for visual outputs.

Long-Term Memory (Codex)

Stores cross-session knowledge (code snippets, solutions) in codex.json, using semantic embedding retrieval (not keyword-based).

Running Modes

4 modes: Chat (default), Action (uses mission_data.txt), NERV (multi-agent:1 Captain +3 Soldiers), Autonomous (runs until task completion with prime_directives.txt).

Configuration & Operational Mechanisms

Configuration via config.cfg

Key options:

  • TEMPERATURE:0.6 (model creativity)
  • CONTEXT_SIZE:65536 tokens
  • HEARTBEAT_SECONDS:1800 (30min idle before background thinking)
  • Plugins toggle (code runner, Codex, image generation, Telegram, web)

Prime Directives

prime_directives.txt defines system prompts, personality (friendly/professional), rules, and ethics to shape MAGI's behavior.

Heartbeat Mechanism

After idle time, MAGI initiates background thinking to decide task continuation, proactive dialogue, or silence—adding proactivity beyond passive Q&A.

Security Measures & Use Cases

Security

  • Code execution: Isolated virtual environments,30min timeout, Ruff static check.
  • Note: File system not fully sandboxed—users should run in trusted environments, backup data, and review code.

Application Scenarios

  • Personal AI assistant (email, code help, info query).
  • Local knowledge base (Codex for team/personal knowledge management).
  • Automation (autonomous mode for long-running tasks like research/monitoring).
  • Multi-agent experiments (NERV mode).
  • Offline use (enterprise intranets without internet access).
