OS4

A FreeBSD-based operating system with the Harmonia agent integrated at the system level. One image, intelligent from boot.

Why OS4

Running an AI agent as an application adds layers: OS, container, runtime, agent. OS4 removes that stack. The Harmonia agent is the OS — with direct access to hardware, process scheduling, and system resources.

For enterprises deploying agents at scale — across factories, vehicles, warehouses, or field equipment — OS4 means deterministic boot and self-improving operations under strict safety gates.

Industry use cases

Industrial Robotics

Factory floor arms, pick-and-place, welding, CNC. Agent-controlled motion planning with real-time safety gates and self-improving process optimization.

Humanoid Robotics

Bipedal and general-purpose humanoid platforms. Harmonia orchestrates perception, locomotion, and task execution with deterministic tick-based control loops.

Automotive

ADAS modules, fleet management, in-vehicle agents. Runs on ARM and x86 ECUs. Hot patching for OTA updates with automatic rollback on failure.

Agriculture

Autonomous tractors, drone swarms, soil monitoring. Low-power ARM deployments on edge devices with MQTT telemetry.

Avionics

UAV autopilot, satellite ground stations, flight data processing. Deterministic scheduling, 9-port capability boundary, and strict validation before any evolution step.

Logistics

Warehouse robots, sorting systems, autonomous delivery vehicles. Agent coordinates fleet tasks, routes, and marketplace procurement for parts and services.

System architecture

OS4 is built on FreeBSD's proven kernel, clean driver framework, and ZFS storage. On top of this:

  • Native Harmonia runtime — Common Lisp orchestration + Rust capability layer as a first-class system service.
  • 9-port capability boundary — vault, store, router, lineage, matrix, tool-runtime, baseband, swarm, evolution.
  • Safe hot patching — Ouroboros (source-rewrite) and Phoenix (binary rollout) with automatic rollback.
  • Harmonic orchestration — 8-phase scheduling for deterministic task execution.

Supported architectures

OS4 compiles natively on each target.

x86_64 / amd64

Servers, desktops, laptops.

AArch64 / ARM64

Raspberry Pi, cloud ARM, embedded.

Full platform details.

Getting started

  1. Download the OS4 image for your architecture.
  2. Boot in a VM or on bare metal.
  3. Harmonia starts automatically — configure via S-expression policy files in /etc/harmonia/config/.
  4. Connect to the Harmoniis marketplace to trade services and procure resources.

Full OS4 documentation

For individuals & enthusiasts

OS4 is open for the community. Install it on a Raspberry Pi, an old laptop, or a server. Run your own self-improving agent on bare metal — no subscription required for the Community tier.

For consumer platforms (iOS, Android, web), see the Harmonia App. For managed deployments with LLM budget included, see pricing plans.

FAQ

What is OS⁴?

OS⁴ is a FreeBSD-based operating system with the Harmonia agent integrated as a native runtime. It boots directly into an intelligent system — no application layer needed.

What architectures does OS⁴ support?

x86_64 (amd64) and AArch64 (ARM64). Covers servers, desktops, embedded ARM boards, and cloud ARM instances.

How is OS⁴ different from the Harmonia App?

The Harmonia App runs on consumer platforms (iOS, Android, web). OS⁴ is a full operating system — you boot into it. The agent gets direct hardware access, system-level scheduling, and tighter orchestration.

Can we deploy OS⁴ across a fleet?

Yes. OS⁴ supports image-based provisioning. Deploy a single image to hundreds of devices. Agents synchronize via genomic (Git) and epigenetic layers.

What about safety-critical environments?

Harmonia runs under explicit validation gates. Every code change and runtime adaptation requires passing safety checks before activation, with automatic rollback on failure.
