GPT-OSS 120B on AI Cube Pro: Run OpenAI's Open-Source Model Locally
With GPT-OSS 120B, OpenAI released their first open-weight model since GPT-2 in August 2025 – and it's impressive. The model achieves near o4-mini performance but...
GPU servers for AI are specialized high-performance servers equipped with NVIDIA RTX Professional GPUs. Unlike conventional servers, they use the parallel computing architecture of graphics processors to train and execute AI models up to 100x faster. Especially for deep learning, neural networks, and large language models, GPUs are indispensable as they can perform thousands of calculations simultaneously.
Hosted in Germany means full GDPR compliance, low latency, and maximum data sovereignty. Your training data and models never leave German jurisdiction – a critical advantage for companies with sensitive data.
Our GPU servers are offered as a managed service: We handle installation, GPU driver optimization, monitoring, and maintenance, while you focus on your AI projects.
The decisive performance advantage
CPUs are optimized for serial computations and typically have 8-64 cores. GPUs, however, have thousands of cores (e.g., in the RTX 6000 Blackwell Max-Q) specifically designed for parallel matrix operations – exactly what deep learning requires.
Modern NVIDIA RTX GPUs feature special Tensor Cores optimized for AI computations. These achieve up to 1457 TFLOPS for FP16 calculations (Mixed Precision Training) – computational power impossible with CPUs.
Training requires GPUs with high VRAM (96GB) to process large models and batches. Inference (production deployment) is about low latency and high throughput – GPUs excel with response times in the millisecond range.
A Llama 70B model that takes 30+ seconds per response on a CPU delivers results in under 2 seconds on an RTX 6000 Blackwell Max-Q. For training workloads, the difference can be even more dramatic: hours instead of days.

We offer both leading open-source frameworks for LLM inference

The beginner-friendly solution for local LLM hosting. Ollama makes it extremely easy to deploy models such as Llama, Gemma or Mistral with a single command. Perfect for rapid prototyping and smaller projects.
Ideal for:
Prototyping, small to medium workloads, simple setup, developer-friendly

The high-performance solution for productive inference workloads. vLLM uses PagedAttention and continuous batching for up to 24 times higher throughput than Ollama. Ideal for applications with high traffic and strict latency requirements.
Ideal for:
Production-ready apps, high-traffic systems, API services, maximum performance
Ollama is ideal for development, prototyping and smaller deployments (up to approx. 50 requests/min). vLLM is the choice for productive high-performance scenarios with hundreds of simultaneous requests. We can run both frameworks in parallel on one server or recommend the right one depending on your use case.

How our customers use GPU servers
A digital agency hosts Llama 70B and Gemma 27B for multiple enterprise clients. The models are used for customer-specific chatbots and content generation. Result: 90% cost savings compared to OpenAI API with full data control. Response time under 2 seconds.
A research institute uses RTX 6000 Blackwell Max-Q for fine-tuning Llama models on German medical datasets. Training that would take weeks on CPUs is completed in 2-3 days. GDPR compliance is guaranteed for sensitive health data.
A mid-sized software company integrates a RAG system (Retrieval-Augmented Generation) into their ERP software. With DeepSeek R1 on RTX 4000 Ada, customer inquiries are intelligently answered – fully on-premise and GDPR-compliant. ROI achieved after 4 months.
An AI startup develops a code review assistant. The prototype runs on GPU Server Basic with Gemma 27B. Cost: €499/month instead of €5,000+ with cloud providers. After product-market fit, upgrade to Pro model for multi-model deployment.
At an average of 1 million tokens per day, OpenAI GPT-4 costs approximately €15,000/month. With your own GPU server: €1,399/month + one-time implementation. Break-even after 2-3 months, then pure cost savings with full data control.

"I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us."
Data Manager, ARGE, Germany
"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) "

"Counting on WZ-IT team was crucial, their expertise and solutions gave us the pace to deploy in production our services, even suggesting and performing improvements over our configuration and setup. We expect to keep counting on them for continuous maintenance of our services and implementation of new solutions."
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)
Robin and Timo provided excellent support during our migration from AWS to Hetzner! We received truly competent advice and will gladly return to their services in the future. (translated)
WZ-IT set up our Jitsi Meet Server anew - professional, fast, and reliable. (translated)
Whether a specific IT challenge or just an idea – we look forward to the exchange. In a brief conversation, we'll evaluate together if and how your project fits with WZ-IT.
