OpenAI GPT OSS - AI Language Models Tool

Overview

OpenAI GPT OSS is an open-source family of large language models, including gpt-oss-120b (117B) and gpt-oss-20b (21B). The models use mixture-of-experts and MXFP4 4-bit quantization, offering chain-of-thought reasoning and tool use support optimized for inference on modern GPUs.

Key Features

  • Two models: gpt-oss-120b (117B) and gpt-oss-20b (21B)
  • Mixture-of-experts (MoE) architecture
  • MXFP4 4-bit quantization for reduced memory and faster inference
  • Powerful reasoning and chain-of-thought capabilities
  • Tool use support for agentic workflows
  • Optimized for GPUs from data-center H100s to consumer hardware

Ideal Use Cases

  • Researching large-scale language model behavior
  • Developing chain-of-thought reasoning agents
  • Building tool-enabled conversational agents
  • Inference benchmarking on diverse GPU hardware
  • Experimenting with MoE and quantization techniques

Getting Started

  • Open the Hugging Face blog post linked in the URL
  • Review model descriptions, release notes, and links on the blog page
  • Follow linked model pages or repositories for download and instructions
  • Prepare a compatible GPU environment for MoE and MXFP4 inference

Pricing

Not disclosed

Limitations

  • Large model sizes require substantial compute and memory
  • MoE and MXFP4 may need specialized inference toolchains and optimizations
