Features of Our GPT-OSS LLM Hosting

Pre-installed with Open WebUI and Ollama, ready to use out of the box. Pairing Open WebUI with Ollama is widely regarded as a very solid and practical solution for self-hosting LLMs.

Seamless Integration

Open WebUI is designed to easily connect with Ollama. It detects Ollama automatically once both are running, and you can manage and chat with your models through a polished web interface.

Rich Feature Set

Open WebUI offers a user-friendly, extensible interface that runs completely offline and supports Ollama, OpenAI-compatible APIs, and advanced features like RAG.

Privacy & Control

Ollama enables strictly local model execution. This ensures your data stays on your machine, enhancing privacy and giving you full control over the environment.

24/7 Support

We provide 24/7 customer support. Simply reach out through a ticket or live chat, and our support team responds promptly, ensuring your concerns are addressed quickly.

Dedicated Resources

Each GPU server comes with dedicated GPU, CPU, and a dedicated U.S. IP address. This isolation ensures your data and privacy are securely maintained.

Flexibility

As your business grows, you can easily adjust resource allocations, upgrading or downgrading your plan to ensure optimal server performance aligned with your requirements.

US-Based Data Centers

Our data centers in the U.S. are monitored 24/7 by a professional team and equipped with camera surveillance to ensure top-notch security.

Admin & Root Access

This full access empowers you to configure your server and allocate resources according freely. You have the freedom to install and download any software without restrictions.

Frequently asked questions

GPT-OSS refers to a family of open-source large language models (LLMs), such as gpt-oss-20b and gpt-oss-120b, that are designed to be alternatives to proprietary models like GPT-4. These models can be self-hosted for private, secure, and customizable use.
gpt-oss-20b: A 20-billion-parameter model suitable for powerful inference on a single high-end GPU or multi-GPU system.
gpt-oss-120b: A 120-billion-parameter model requiring high memory bandwidth and typically multiple GPUs for optimal performance.
To run GPT-OSS models efficiently, we recommend:
For 20B: 1× A4000 16GB, or 1× RTX 4090 24GB
For 120B: 1× A100 80GB, or 2× A100 40GB with NVLink or high-speed interconnect
B2BHOSTINGCLUB offers GPU servers with flexible hourly/monthly pricing to match these needs.
Yes. To run GPT-OSS models, you’ll typically need:
Ollama, vLLM, or Open WebUI as the inference server
Python ≥ 3.10
CUDA drivers for GPU acceleration
Model weights from Hugging Face or other open repositories
We can pre-install these upon request.
Yes. gpt-oss-20b and other models can be loaded via Ollama by configuring your Modelfile and downloading the weights. Ollama also provides a local API for integration with applications.
Absolutely. Since GPT-OSS runs on your dedicated GPU server, no data is sent to third-party APIs. It’s ideal for privacy-conscious users and enterprises.
Yes, our servers fully support Docker with GPU passthrough. You can use Docker images for Ollama, Text Generation Web UI, or vLLM to containerize your LLM workloads.
Yes. When ordering, you can choose to have:
Pre-installed Ollama, Python, CUDA
Your chosen model (e.g., gpt-oss-20b)
Web UI or API interface ready to go
Just let our team know your preferences during setup.
Choose a compatible GPU server on B2bhostingclub.com
