Large language models keep growing, and teams now want full control over data and cost. That is why many developers choose to host an LLM on a GPU VPS instead of relying on pay-per-token APIs. This guide covers the entire process, from picking hardware to exposing a private endpoint, and shows why a HostingB2B GPU VPS makes self-hosting simple.

What Is Hosting an LLM on a GPU VPS?

Hosting an LLM on a GPU VPS means running a language model on a virtual server with a dedicated graphics card, rather than calling a third-party API. Consequently, you keep full control over prompts, outputs, and inference cost. Because the GPU handles the heavy math, response times stay fast even for large models. As a result, self-hosting suits teams that need privacy, predictable pricing, or custom fine-tuning.

What You Need to Host an LLM (GPU, VRAM, OS)

GPU and VRAM Requirements

First, you need a GPU with enough VRAM for your model. A 7B Llama variant runs on 16 GB, while a 70B model needs 80 GB or more. Therefore, check the model card first, since a VRAM shortfall causes a crash, not a slow response.

Operating System and Drivers

Ubuntu remains the standard choice because CUDA support is mature. Afterward, update the NVIDIA drivers so the GPU is fully recognized.

Choosing the Right GPU VPS

Next, match your model size to the right GPU Server. The table below compares HostingB2B’s V100S, A100, and Blackwell options.

Step-by-Step: Deploy and Run Your Model

Step 1: Deploy and Access Your GPU VPS

Once you pick a plan, deploy your server within minutes. HostingB2B’s GPU VPS plans include pre-configured CUDA images, so you skip hours of manual setup.

Step 2: Install Drivers, CUDA, and Your Inference Engine

Next, install the NVIDIA driver stack and pick an engine. vLLM offers high throughput, while Ollama suits quick testing.

Step 3: Download and Run Your Model

Then, pull your chosen weights, for example Llama, Mistral, or DeepSeek, from Hugging Face, and run a test prompt to confirm the model responds correctly.

Step 4: Expose a Private API Endpoint

Finally, wrap your model in an API layer so internal apps can call it securely, without sending data outside your own infrastructure.

Self-Hosting vs Pay-Per-Token APIs: Cost and Privacy

Pay-per-token APIs need no setup, but costs rise fast at scale. In contrast, choosing to host an LLM on a GPU VPS gives fixed pricing and full data privacy, so high-volume workloads usually save money within months.

Common Use Cases by Industry

  • Fintech: private document analysis, kept off third-party servers.
  • Healthcare: on-premise-style inference for stricter compliance.
  • iGaming: real-time chat moderation and support bots.
  • SaaS: embedding custom copilots inside an existing product.

Across every industry, teams generally self-host when data control matters more than convenience.

Enterprise Deployment Considerations

For production, plan for redundancy, backups, and continuous monitoring from day one. Additionally, apply strict access control on your API endpoint. Furthermore, HostingB2B’s enterprise GPU VPS plans include monitoring and backups, so scaling from pilot to production stays straightforward.

FAQ

How much VRAM do I need for a 70B model?

Generally, 80 GB or more, while small models fit in 16 GB.

Is self-hosting cheaper than API calls?

Yes, for consistent high-volume traffic, self-hosting typically costs less.

Which inference engine should I use?

Generally, vLLM suits throughput, while Ollama suits quick testing.

Can I self-host without deep Linux experience?

Basic knowledge helps, but pre-configured images reduce most setup steps.

Is my data private when self-hosting?

Yes, since everything runs on your own server, nothing leaves your infrastructure.
