LLM Hosting Germany
Hosting Large Language Models (LLM) in Germany – secure, high-performance and ready for operation. GDPR-compliant with dedicated GPU infrastructure.
What are Large Language Models (LLMs)?
Large Language Models (LLM) are AI models that can understand and generate natural language. For companies, they offer enormous opportunities: from automating customer communication and intelligent document analysis to coding assistants and knowledge management.
With our LLM Hosting Germany, you can operate these powerful models in your own GDPR-compliant infrastructure – without having to pass on your sensitive data to global cloud providers.
Whether Llama 3.1, Gemma 3, DeepSeek-R1 or other open-source models – we take care of the installation, operation and optimization of your LLM infrastructure.
Why Host LLMs Locally in Germany?
Full control over your AI infrastructure
Data Protection & GDPR
Your data stays in Germany and never leaves the EU. Full GDPR compliance without compromising on functionality.
Data Sovereignty
In contrast to OpenAI, AWS or Azure, you have full control: no data transfer to third parties, no training with your data, no hidden API calls.
Compliance & Audits
Meet strict compliance requirements in regulated industries such as healthcare, finance or public administration.
Cost Efficiency
No hidden API costs, no surprises when it comes to billing. Predictable monthly fixed costs instead of pay-per-token with cloud providers.
Performance & Latency
Dedicated GPU resources without sharing. Optimal latency for your applications without dependence on global cloud services.
Adaptability
Fine-tuning and customization of your models to your specific requirements. No restrictions from API limits or vendor lock-ins.
Infrastructure Requirements for LLM Hosting
What is needed for professional LLM hosting?
Hosting Large Language Models places special demands on the infrastructure. We ensure that everything is optimally configured.
Hardware & GPU
LLMs require powerful GPUs with sufficient VRAM. For Llama 3.1 70B we recommend at least 48 GB VRAM, for smaller models like Gemma 3 27B, 20 GB is sufficient. Our servers are equipped with NVIDIA RTX 4000 (20 GB) or RTX 6000 Ada (48 GB).
Memory & Storage
In addition to GPU memory, you need sufficient RAM (at least 64 GB) and fast NVMe storage for model files and caching. The models themselves occupy between 15 GB (7B parameters) and 150 GB (70B parameters).
Network & Bandwidth
For production applications with multiple users, a stable, fast network connection is essential. Our servers offer gigabit connectivity with low latency within Germany.
Software & Updates
The complete software stack including CUDA drivers, Ollama, OpenWebUI and container orchestration is installed, configured and kept up-to-date by us.
Monitoring & Security
Professional monitoring of GPU utilization, temperature management, automatic backups and security updates are part of our service.
Scaling & Load Balancing
As requirements grow, we scale your infrastructure horizontally (multiple servers) or vertically (more powerful GPUs). Load balancing between multiple instances is possible.

Support & Consulting
Our team supports you with model selection, integration into your applications and optimization for your specific use cases. Priority support via email and optionally phone/video.

"With Timo and Robin, you're not only on the safe side technically - you also get the best human support! Whether it's quick help in everyday life or complex IT solutions: the guys from WZ-IT think along with you, act quickly and speak a language you understand. The collaboration is uncomplicated, reliable and always on an equal footing. That makes IT fun - and above all: it works! Big thank you to the team! (translated) "
Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)
We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)
