GPU Serverpowered by OpenStack

GPU performance for AI, simulation and rendering — on Swiss infrastructure. stepping stone offers dedicated NVIDIA RTX PRO 6000 Blackwell GPUs with up to 96 GB of vRAM: full access, no shared resources, AI-ready from the very first minute.

With stepping stone’s GPU servers, you get dedicated computing power for AI workloads, physical simulations and 3D rendering — hosted in Switzerland. Each virtual machine has full access to NVIDIA RTX PRO 6000 Blackwell GPUs with 96 GB of vRAM per GPU, and you can combine up to eight GPUs per VM.

The resources are fully dedicated: 1 to 256 vCPUs and up to 2 TB of RAM, with no CPU overbooking. GPU access is via PCIe passthrough — custom drivers are supported, and the latest drivers are regularly updated and maintained by stepping stone. AI-ready images are available to get you started quickly: Ollama, vLLM, Open WebUI and Hugging Face CLI are pre-installed, along with accompanying guides, so you can be up and running within minutes. stepping stone operates its GPU infrastructure entirely in Swiss data centres — your data and models remain in Switzerland.

Research teams, developers and companies that need GPU performance for computationally intensive workloads — without having to purchase their own hardware and without handing over data to US cloud providers.

Typical areas of application: LLM inference and training on local infrastructure, reinforcement learning and machine learning workflows, physical simulations (molecular dynamics, protein folding), 3D rendering and visualisation, AI prototyping using pre-installed tools and guides.

The bandwidth of stepping stone AG will be calculated with the 95%-rule.The 95%-rule is a common standard. 

Calculation of the 95%-rule

When you have ordered a bandwidth of 1 Megabit/s and are connected to a 100 Megabit/s line, the Committed Data Rate (CDR) is 1 Megabit/s with a burst rate of 100 Megabit/s. The Committed Data Rate will be invoiced independently of the usage, as this bandwidth is fixed reserved for you. The burst rate of 100 Megabit/s is “best effort” and will be invoiced according to the 95%-rule, which is calculated as follows:
