AI Act · Sovereignty · On-premise AI

Bring AI into compliance, and keep control of the models.

The AI Act regulation (EU 2024/1689) requires risk classification for every AI system in use, reinforced obligations on high-risk uses, and Article 50 transparency for interaction systems. Luxgap supports your end-to-end AI Act compliance, and offers software whose architecture lets you pick the AI engine: commercial GPAI to get started fast, or open-source on-premise AI for full sovereignty.

Pillar 1 · Compliance

AI Act compliance for your AI systems.

Whether AI is developed in-house, bought from a vendor or embedded in a SaaS, you are accountable for its compliance. The schedule is known: prohibited uses since February 2025, GPAI since August 2025, high-risk systems from August 2026. Our AI lawyers scope, qualify, document and pass the audit.

01. Inventory and classification

Inventory of every AI system in production or planned (including AI embedded in HR, marketing, anti-fraud SaaS). AI Act classification: prohibited, high-risk, limited risk, minimal risk. Continuously maintained AI system register.

02. High-risk documentation

For every high-risk system: technical documentation (Annex IV), quality management system (Article 17), risk management (Article 9), human oversight (Article 14), DPIA coupled with GDPR if personal data is processed. Everything ready for market placement or ILR inspection.

03. Article 50 transparency

Chatbots, generated content, deepfakes, emotion recognition systems: mandatory disclosure to users. We write compliant wordings, information banners, and update your T&Cs. Synthetic content marking on the technical side.

04. Governance and usage charter

Internal AI committee, new tool review process, employee charter (Copilot, ChatGPT, Claude, etc.), incident procedure, register of significant AI decisions. Direct link with the external DPO mandate when personal data is involved.

05. Team training

AI Act Article 4: AI literacy is mandatory for any employee using an AI system. Training tailored by function (HR, finance, legal, ops), with the certifying PECB offer if requested.

06. Annual audit and watch

Annual audit to confirm posture, documentation refresh, watch on implementing acts, CEN-CENELEC harmonised standards, and AI Office decisions. As your systems evolve, the register follows.

Pillar 2 · Architecture

Your Luxgap software, two AI engines to choose from.

All our software (DPO Assist, KYC Luxembourg, Third Party Register, GDPR erasure, LuxApps SIRH) is built on the same architecture: a business layer decoupled from the AI engine. You choose your engine based on regulatory and sovereignty constraints. The business layer stays the same.

Commercial cloud GPAI

Claude · OpenAI · Mistral · Gemini

For uses where data can transit through a GPAI provider, you immediately benefit from the best models on the market (Claude Opus 4.7, GPT-5, Mistral Large, Gemini 2.5). European contracting, no data reuse for training, Luxgap-side logging for audit. Ideal for note-taking, summarisation, classification, drafting assistance.

  • Rollout in days, not months
  • Best-in-class models continuously updated
  • EU contracts, negotiated CLOUD Act immunity

On-premise open-source AI

Llama · Mistral · Qwen · vLLM · Ollama

For data that must not leave your infrastructure: Article 41 LSF banking secrecy, defence, health, classified data. Production-grade open-source models (Llama 3.3 70B, Mistral 8x22B, Qwen 2.5 72B) installed on a dedicated server at your site, behind your firewall, with no outbound API calls. Strict versioning for reproducible audit.

  • Zero outbound calls, data stays put
  • Versioned models, reproducible audit
  • Compatible with Art. 41 LSF, defence, HDS

Automatic routing: within the same software, you can route sensitive tasks to the on-premise engine and benign tasks to the cloud engine. Policy by field, by client, by document type. No proprietary lock-in.

Pillar 3 · Sovereign response

Built for States and regulated companies.

When AI touches state secrecy, banking secrecy, medical secrecy or defence secrecy, the choice of engine is not a preference: it is an obligation. Our software is built for that constraint from the very first ticket.

Public sector and States

Ministries · Municipalities · Defence · Hospitals

  • On-premise deployment on the administration's infrastructure, no outbound
  • Versioned open-source models, bit-by-bit reproducible audit
  • Full EU sovereignty, immunity from CLOUD Act and FISA 702
  • Compatible with national classifications (Restricted, Confidential)
  • AI Act documentation ready for the notifying authority

Regulated companies

Banks · Funds · Trustees · Insurance · Health

  • Banks under Article 41 LSF secrecy: on-premise engine mandatory for nominative data
  • CSSF funds and trustees: routing by data category, CSSF audit prepared
  • DORA Article 28-30: AI register integrated into the Register of Information
  • Health: HDS-compatible hosting, patient access logging
  • CAA insurance: model governance documented for internal control
Why Luxgap

An AI Act file requires three skill sets at once.

A law firm does the AI Act analysis but does not touch code. A tech integrator installs the AI but ignores legal obligations. A cyber consultant secures it but validates neither the law nor the model architecture. Luxgap brings all three teams to every AI file.

Lawyers AI Act + GDPR

Risk classification, coupled DPIA, AI vendor contracts, Article 50 transparency, usage charter. External DPO mandate extended to AI available.

Cybersecurity engineers

Infra hardening (dedicated server, segmentation, FIDO2 MFA, encryption), model governance, AI incident response, ISO 27001 compliance of the deployment, external CISO if needed.

Sovereign AI developers

Modular architecture (business layer + swappable AI engine), fine-tuning on your data, IT integration, automated tests. Stack: Python/FastAPI, PostgreSQL, vLLM, Ollama, Mistral, Qdrant. No uncontrolled US cloud dependency.
