gpt-oss-20b-DGX-Spark-GGUF

gpt-oss-20b

This repository provides GGUF quantized versions of OpenAI's gpt-oss-20b, optimized specifically for NVIDIA Blackwell (DGX Spark) architectures.

These models were converted and quantized using llama.cpp with support for the gpt_oss architecture.

Model Highlights

Optimized for Blackwell: Specifically tuned for high-performance inference on NVIDIA DGX Spark (SM120/SM121).
Flexible Quantization:
- Q4_MXFP4: 4-bit Medium quantization (recommended for efficiency).
- Q8_0: 8-bit quantization (recommended for maximum precision).
MoE Architecture: 21B total parameters with 3.6B active parameters, leveraging Mixture-of-Experts for high efficiency.
Long Context: Supports up to 131k context length.

Quantization Details

File	Quant Method	Bitrate	Size	Description
`gpt-oss-20b-q4_mxfp4.gguf`	Q4_MXFP4	4.5 bpw	~12 GB	Balanced performance and quality.
`gpt-oss-20b-q8_0.gguf`	Q8_0	8.5 bpw	~22 GB	Standard 8-bit quantization.

Quick Start (llama.cpp)

To run these models on a DGX Spark system:

Pull the optimized Docker image:

docker pull ghcr.io/sowilow/dgx-spark-llama.cpp-bench:latest

Run with llama-server:

docker run --gpus all -v $(pwd)/models:/model \
    ghcr.io/sowilow/dgx-spark-llama.cpp-bench:latest \
    llama-server -m /model/gpt-oss-20b-q4_mxfp4.gguf -ngl 99 -c 8192
