How RakuAI™ Works

RakuAI is the deterministic authority runtime. External agents reach the engine through a fixed 17-tool native MCP boundary — the engine stays in charge of physics, collision, scoring, and multiplayer state.

Modular, AI-Native Architecture

A purpose-built modular engine covering rendering, physics, audio, AI, XR, networking, and more. Lightweight runtime with no cloud dependencies. Load only what you need.

Modular architecture: a runtime core surrounded by composable subsystem modules — rendering, physics, audio, AI, XR, networking, animation and scripting — each loadable on demand. RakuAI runtime core Rendering Physics Audio AI / SLM XR Networking Animation Scripting

Why RakuAI?

5 granted US patents. Priority July 2012. Decade-old IP that anchors today’s AR-glasses category. 18 native DLLs. 17 router modules. 9,500+ REST endpoints. 10,328 bound engine functions. The runtime that Claude, ChatGPT, Gemini, and Copilot all drive — multi-vendor by design.

Unity’s MCP targets scene manipulation at design time. RakuAI’s MCP is for world-model orchestration at runtime — every frame, every NPC, every interaction. Unreal needs an RTX 4090. RakuAI needs Wi-Fi 7 and a phone.
