Local AI.
Sovereign by design.

A platform for your knowledge, your voices, your agents and your avatars — entirely on your infrastructure, in your country, under your control.

Not a roadmap. A turnkey AI platform — 20+ models for text, speech, vision, video, music and avatars, integrated and production-tested on local hardware. Deploy the full stack, or start with the one component that solves your most urgent constraint.

I · THE PROBLEM Why today is not enough for tomorrow

The cloud knows your customers
better than you do.

Every productive AI interface bought today is also a data outflow. For an organisation with high sovereignty requirements, that is not a compliance detail — it is the foundation of the business.

01

Sovereignty is not negotiable.

GDPR, NIS-2 and sector-specific regulations require that business data and sensitive content remain under your control. Public-cloud AI APIs see everything they are shown — and reserve training rights on it.

02

Latency and cost scale the wrong way.

Per-token billing gets expensive the moment a use case grows. With every increase in adoption you pay providers — instead of building an asset. Availability hangs on a third party's contract.

03

Knowledge you train is not yours.

Models you fine-tune on hyperscaler APIs are fragile as assets. If licence, price or availability changes, years of work evaporate — classic lock-in.

II · USE CASES Concrete. Feasible. For your operation.

Four fields with
immediately visible returns.

CASE 01

Internal knowledge portal for employees

RAG across Confluence, SharePoint, internal wikis, runbooks, specifications, ticket histories and engineering decisions. Answers in natural language, with source citations. Reduces tier-1 escalations and makes onboarding colleagues productive from week one.

RAGLLMSSOAudit
CASE 02

Coding agent for engineering teams

Aethos Coder inside your network. Pull-request reviews, test generation, refactoring across enterprise repositories. Even sensitive areas such as financial transactions, compliance workflows or production control stay sovereign — no code snippet leaves the data centre.

SkillsRepo-RAGSAST
CASE 03

Voice agent for service desks & hotlines

Local STT & TTS plus LLM for service-desk requests, orders, status queries or self-service scenarios. Multilingual (English, German, further languages), with seamless handoff to human agents. Full conversation telemetry stays in your hands — GDPR-compliant, without third-party APIs.

WhisperF5-TTSAvatar opt.
CASE 04

AR/VR training for safety-critical work

Maintenance procedures, safety protocols, onboarding and complex manual steps as immersive training with an AI coach. The avatar spots mistakes in the workflow, answers questions, documents progress. Scales training without training rooms — and without sensitive process documentation leaving the secure zone.

III · HARDWARE Your facility · Your tempo

Your hardware.
Your data. Your tempo.

Aethos is optimised for modern local hardware — from NPU-driven edge nodes to GPU clusters in the data centre. The figures below come from production measurements on our reference platform.

50TOPS NPU performance AMD Ryzen AI MAX+ 395 · XDNA 2
2.6× Real-time STT Whisper Base on NPU · RTF 0.38
8.4× Real-time TTS Kokoro · 55 voices
6.7× End-to-end speedup GPU pipeline vs. CPU baseline

Three deployment modes, one stack.

Air-Gap

Fully isolated deployment in protected zones. No outbound network traffic. Updates via signed packages. Suited for particularly sensitive areas.

On-Premise

Classic installation in your data centre. Central model and skill registry. Integration with SSO, LDAP, SIEM and existing audit pipelines.

Hybrid Edge

Local NPU nodes in branches, field notebooks or VR stations, synchronised with the central data centre. Low latency on-site, central data control.

V · NEXT STEPS Three ways to begin together

Let us start with what
proves itself immediately.

We recommend a staged entry: a one-day architecture workshop, a six-week proof of concept, then a pilot operation with real users. Each stage is valuable on its own and decides on the next.

Stage 01

Architecture workshop

1 day · on site

We map your priority use cases, survey the existing data landscape and design the target architecture.

  • Use-case mapping
  • Data & compliance audit
  • Feasibility assessment
  • Roadmap draft
Stage 02

Proof of concept

6 weeks · sandbox

One priority use case, running in your test environment with real data, clear success metrics and clean handover.

  • Local model deployment
  • RAG across your data sources
  • User-acceptance measurement
  • Handover documentation
Stage 03

Pilot operation

3–6 months · production

Productive pilot with real users, full telemetry, tuning cycles and documented handover to your internal teams.

  • SLA & monitoring
  • Skill and model tuning
  • Training of your teams
  • Scaling plan
VI · CONTACT Let us start the conversation

Local AI is not a product you buy.
It is an asset you build.
