I am having trouble installing and/or using gpt-oss:20b

If you have any difficulties or questions when installing and/or using this software, carefully review the documentation on the developer’s official website, read about typical problems and how to solve them or contact OpenAI support.

gpt-oss:20b key features

The gpt-oss:20b model is well-suited for a wide range of practical tasks especially where you want strong performance without relying on cloud APIs or proprietary services.

Free and open-source

You can freely use, modify and deploy the model, including for commercial purposes, without copyleft restrictions or patent concerns according to Apache 2.0 License.

High data security

With self-hosted gpt-oss:20b, all your data stays and is handled entirely on your own servers, so there is no processing that takes place outside your system or network.

MoE Architecture

Gpt-oss:20b model uses a Mixture of Experts (MoE) system that only activates a few expert parts at a time, making it faster and more efficient without sacrificing quality.

Configurable Reasoning Effort

You can set the reasoning level, i.e. Low, Medium or High, to balance between speed and depth of response depending on your needs.

Full Chain-of-Thought (CoT) Access

The model output includes its full reasoning trace, which helps with debugging and understanding the logic (though it's usually not shown to end users).

Fine‑tuning Capabilities

You can adapt the model to specific domains or tasks using parameter fine-tuning, even on consumer-level hardware.

Agentic Capabilities

It natively supports advanced tasks like function calling with schemas, web browsing, executing Python code and generating structured outputs.

Native MXFP4 Quantization

Using MXFP4 precision for the mixture-of-experts (MoE) layers lets the 20B model run locally within a 16 GB RAM constraint

Low‑Hardware Footprint Deployment

With just around 21 B parameters and efficient MoE architecture, the model is optimized for local or edge deployment on modest compute setups.

What customers say

After launching another successful IP — HUNT: Showdown, a competitive first-person PvP bounty hunting game with heavy PvE elements, Crytek aimed to bring this amazing game for its end-users. We needed a hosting provider that can offer us high-performance servers with great network speed, latency, and 24/7 support.

Stefan Neykov Crytek

doXray has been using HOSTKEY for the development and the operation of our software solutions. Our applications require the use of GPU processing power. We have been using HOSTKEY for several years and we are very satisfied with the way they operate. New requirements are setup fast and support follows up after the installation process to check if everything is as requested. Support during operations is reliable and fast.

Wimdo Blaauboer doXray

We would like to thank HOSTKEY for providing us with high-quality hosting services for over 4 years. Ip-label has been able to conduct many of its more than 100 million daily measurements through HOSTKEY’s servers, making our meteorological coverage even more complete.
