AI hosting – run your own AI applications securely in Germany
Artificial intelligence without depending on US clouds: we provide the platform for your own AI applications. Automate workflows with n8n, run language models such as Llama, Mistral or Qwen with Ollama and Open WebUI, and rent dedicated servers with NVIDIA graphics cards for demanding workloads.
Your data, prompts and documents stay under your control – in Germany, GDPR compliant and with a provider certified to ISO/IEC 27001. We set up the environment, keep it up to date and advise you on which models and which hardware suit your project. As GPU prices fluctuate strongly, you receive an individual offer from us.

What we provide for your AI
From the first automation to your own language model on dedicated GPU hardware – fully managed and on request.
n8n – automate workflows
AutomationConnect CRM, shop, email and hundreds of other services and let AI steps work directly in your processes. We operate your own n8n instance – with updates, backups and monitoring, without the limits of cloud plans.
Language models with Ollama
LLMOpen-source models such as Llama, Mistral, Qwen, Gemma or DeepSeek run on your own server. Via an API you integrate the models into your applications, n8n or your software.
Your own AI chat with Open WebUI
ChatA chat interface like ChatGPT for your team – with user management and your own models. Confidential content never leaves your server.
AI with your own data
RAGDocuments, manuals and company knowledge as the basis for answers (RAG): we set up the vector database, models and interfaces to match your use case.
Dedicated GPU servers with NVIDIA
GPUFor large models, training, fine-tuning or image processing you rent dedicated servers with NVIDIA graphics cards. We match the configuration and GPU to your requirements and current availability.
Advice and operation
personalWhich model, how much GPU memory, CPU or GPU? We advise you independently, implement the environment and, on request, take care of operation and security permanently.
Which environment suits your project?
Not every AI application needs a graphics card. This overview helps with a first assessment – we define the exact configuration together.

|---|---|---|
| Automation with n8n workflows, interfaces, AI APIs |
Managed vServer or enterprise cloud | on request |
| Small language models tests, simple assistants |
Server with plenty of RAM, running on the CPU | on request |
| AI chat and RAG for teams Ollama, Open WebUI, vector database |
Dedicated server with NVIDIA GPU | on request |
| Large models, training, fine-tuning high GPU memory |
Dedicated server with powerful NVIDIA GPUs | on request |

Personal support
You talk directly to experienced specialists who know your system and personally take care of your request.
Since 1995
More than 30 years of hosting experience – and for many years specialised in source code hosting and development environments.
Custom solutions
Whether a single GitLab server, a cluster or a special setup with VPN connection to your company network: we design the environment that fits your requirements.
Our own cloud platform
With the Virtuozzo Enterprise Cloud (VEP) we run our own cloud platform made in Germany – for highly available and business-critical workloads.
Frequently asked questions about AI hosting
Why should I run AI myself instead of using a cloud service?
With public AI services, your input and documents leave your company and are often processed outside the EU. With your own AI environment at LCube, data, prompts and results stay on your server in Germany. You decide which models to use, pay no fees per request and are independent of price changes and terms of use of large providers.
What is n8n and what can I use it for?
n8n is a platform for automating workflows. It connects applications such as CRM, shop, email or accounting via ready-made building blocks and custom interfaces. AI steps can be built in directly, for example to classify emails, summarise texts or prepare enquiries. We operate n8n as your own instance so that your workflows and credentials are not stored with a cloud provider.
Which language models can I run with Ollama?
Ollama supports many open-source models, for example Llama, Mistral, Qwen, Gemma or DeepSeek in different sizes. Which model fits depends on your task, the desired quality and the available hardware. Small models already run on powerful CPUs, larger ones need an NVIDIA GPU with sufficient graphics memory. We advise you on the selection and set up the models.
Why are there no fixed prices for GPU servers?
Prices for NVIDIA graphics cards and GPU servers currently fluctuate strongly and depend on model, availability and term. Fixed list prices would therefore quickly become outdated. Instead, we prepare an individual offer based on the current market situation and your requirements. This way you get exactly the performance your project needs at a fair, up-to-date price.
Do I always need a graphics card for AI?
No. For automation with n8n, connecting external AI interfaces or small language models, a well-equipped server without a GPU is often enough. An NVIDIA graphics card pays off when several people work with your own model at the same time, larger models should respond quickly or you want to train and adapt models. We check together with you which configuration is really necessary.
How secure is my data in the AI environment?
Your environment runs on your own servers in Germany, operation is GDPR compliant and LCube is certified to ISO/IEC 27001. Your data is not used to train third-party models. We keep the operating system and applications up to date, back up the data regularly and, on request, protect access via VPN or single sign-on. This lets you use AI for confidential company data too.
