AitherOS is an operating system for AI agents — software that runs tasks, remembers things, and uses tools for you, on hardware you own. Try it in your browser right now: no account, nothing to install, and the model can run entirely on your own machine. The whole stack is built in the open —260 services and 20 agents — and stewarded by the Aitherium Foundation: open weights, open code, no lock-in. Your hardware. Your data. Your agents.

Architecture Highlights
An OS for agents, not a chatbot
Agents with memory, tools, and infrastructure — they do the work, not just answer questions.
20 specialized agents with capability-based dispatch and agent-to-agent mesh communication.
AitherADK: the open-source Agent Development Kit for building, testing, and deploying your own agents.
Runs on hardware you own
The model loads into your own GPU — laptop, desktop, even your browser. Not a datacenter, not a meter.
Bonsai: our 27B multimodal model that runs on a normal CPU, or in-browser over WebGPU — no account, no server.
One command stands up the full stack on a Linux box you own — sovereignty is an architecture decision.
Security by default
HMAC-SHA256 capability tokens with a default-deny security model.
Ed25519 inter-service request signing with automatic key rotation.
RBAC with tenant isolation and caller context propagation — nothing trusts the payload.
Built in the open, owned by no one
The Aitherium Foundation stewards the open layer of AI: open weights, open code, no infinite scaling.
The platform, the models, and the serving stack run on ordinary machines — the fleet is the daily test.
Local-first infrastructure: multi-model serving, VRAM-coordinated GPU scheduling, cloud overflow only when you choose it.
