Introduction
OpenHuman is an open-source personal AI platform built in Rust that runs entirely on your own hardware. It aims to provide a capable, general-purpose AI assistant while guaranteeing that no data leaves your device, making it suitable for privacy-conscious users and organizations.
What OpenHuman Does
- Provides a locally-running AI assistant with chat, code, and reasoning capabilities
- Keeps all conversations, data, and model weights on your hardware
- Supports multiple model backends for flexible hardware utilization
- Offers a web UI and CLI interface for interaction
- Includes plugin and extension points for custom capabilities
Architecture Overview
OpenHuman is implemented as a Rust binary that bundles a web server, model inference coordinator, and plugin runtime. The core communicates with local model backends through a unified adapter layer. A built-in web frontend provides the chat interface, while a CLI mode enables terminal-based interaction. All state is persisted locally in SQLite.
Self-Hosting & Configuration
- Build from source with the Rust toolchain or download a pre-built binary
- Point to a local model server or use the built-in inference engine
- Configure via a TOML config file specifying model paths, port, and plugin settings
- Data is stored locally in ~/.openhuman by default
- Supports running behind a reverse proxy for remote access to your own instance
Key Features
- Complete data privacy with zero external network calls during inference
- Written in Rust for memory safety and performance
- Extensible plugin system for adding custom tools and integrations
- Works with consumer-grade hardware, no data center required
- Multi-modal support for text and document understanding

FAQ
Q: What hardware do I need? A: A modern CPU with 16 GB RAM can run smaller models. A GPU accelerates larger models significantly.
Q: Which models are supported? A: Any GGUF or SafeTensors model compatible with the configured backend, including Llama, Mistral, and Qwen families.
Q: Is there a mobile app? A: Not currently. Access is via the web UI in a browser or the CLI.
Q: Can multiple users share one instance? A: Yes, the web server supports concurrent sessions. Authentication can be configured for multi-user setups.
