How we work with you

You don’t have to set up vLLM on your own. We accompany you step by step – and stay by your side afterwards.

Step 1

Analysis & concept

We look at your use cases, models and existing GPU hardware and plan together which setup really fits. We know the pitfalls from practical experience - so you avoid oversized hardware or a setup that collapses under load.
"
Step 2

Structure & integration

We set up vLLM to fit perfectly: Model selection, quantization, GPU allocation and the OpenAI-compatible API - neatly integrated into your systems, if desired via Docker and Kubernetes. A well thought-out design saves you expensive conversions later on and scales with your needs.
"
Step 3

Commissioning & Serving

Your LLM endpoint goes live and serves many simultaneous requests efficiently - thanks to PagedAttention and Continuous Batching at maximum GPU utilization. This avoids expensive idle times and latency peaks that affect productive applications.
"
Step 4

Support & Operation

On request, we can take over ongoing operations completely (outsourcing) or support your team with support and training. Updates, scaling and GPU monitoring take up a lot of time internally - we keep your LLM serving stable so that you can concentrate on your core business.

vLLM Features

Operate large language models on your own GPU infrastructure in a high-performance and GDPR-compliant manner

High throughput thanks to PagedAttention

vLLM uses the GPU memory much more efficiently with the PagedAttention technology and achieves a multiple of the throughput of classic serving methods via continuous batching. This allows you to handle many simultaneous requests without constantly buying new hardware.

Self-hosted & GDPR-compliant

vLLM runs entirely on your own infrastructure – via Docker or Kubernetes, on-premise or in your cloud. No prompts and no responses leave your server, which makes vLLM particularly interesting for privacy-sensitive use cases.

OpenAI-compatible API

vLLM provides your model via an OpenAI-compatible interface. Existing applications and SDKs can be connected without conversion – you just swap the endpoint and retain full control over the model and data.

Over 200 models & hardware flexibility

vLLM supports over 200 model architectures from Hugging Face, including Llama, Mistral and Qwen. It runs on NVIDIA and AMD GPUs as well as other accelerators – you remain flexible in your choice of model and hardware.

Distributed inference for large models

Using tensor and pipeline parallelism, vLLM distributes large models across multiple GPUs. This allows you to operate models that do not fit into the memory of a single GPU – scalable from two to many GPUs.

Open source & cost-efficient

vLLM is open source under Apache 2.0 and is maintained by over 2,000 contributors. Instead of ongoing costs per token, you only pay for your hardware – a clear cost advantage over hosted AI services for high loads.

Shaping IT together

We help you to strategically plan, technically implement and sustainably operate modern AI and inference solutions. We combine consulting, implementation and support to create a tailor-made service that is geared to your requirements. Our aim is to make high-performance LLM deployments transparent, stable and efficient to use.

Questions & Answers

The most frequently asked questions about vLLM

What is vLLM simply explained?

2
3
vLLM is an open-source inference engine with which you can provide large language models on your own GPU servers. It ensures that many requests are processed efficiently at the same time and makes the model available via an OpenAI-compatible interface. This allows you to operate AI models with high performance in your own environment.

Is vLLM open source?

2
3
Yes. vLLM is open source under the Apache 2.0 license and is developed by a large community of research institutions and companies. The complete source code is publicly available on GitHub, and you can use vLLM freely.

What does vLLM cost?

2
3
The software itself is free of charge. Costs are incurred for the GPU hardware or cloud instances as well as for our services relating to implementation, operation and training. On request, we operate vLLM managed via NWS. Just ask us about the possible costs.

Is vLLM GDPR-compliant?

2
3
vLLM is pure software and does not store any data itself. If you run it on your own hardware or in a European data center, your data never leaves your environment. This makes vLLM particularly suitable for data protection-sensitive use cases - a clear advantage over external AI APIs.

What hardware do I need for vLLM?

2
3
This depends on the model size. Smaller models already run on a single modern GPU, while large models require several GPUs with distributed inference. We analyze your needs and recommend the right hardware - or you can use GPU instances via NWS.

How does vLLM differ from Ollama?

2
3
Ollama is optimized for local development on a single computer. vLLM is aimed at productive operation with many parallel users on GPU servers. Those who put LLMs into production generally rely on vLLM - both complement each other in the typical development stack.

Which models does vLLM support?

2
3
vLLM supports over 200 model architectures from Hugging Face, including popular open source models such as Llama, Mistral, Qwen and many more. Both instruction-tuned and basic models can be operated, as well as your own fine tunes.
