Why This Matters: Democratizing Cutting-Edge AI
These flexible, open-weight text-reasoning Large Language Models (LLMs) are your toolkit for the future. Think breakthrough applications in:
- Generative AI
- Advanced Reasoning AI
- Physical AI (robotics, automation)
- Healthcare innovation
- Smart manufacturing
- And even unlocking entirely new industries as the AI-driven industrial revolution accelerates.
Powered by NVIDIA, Optimized for Performance
Trained on NVIDIA’s powerhouse H100 GPUs, these models are built for the real world. They run inference best on the hundreds of millions of GPUs powered by the ubiquitous NVIDIA CUDA platform globally. Need a deployment that’s easy, flexible, secure, and respects data privacy? They’re now available as NVIDIA NIM microservices, ready to roll on any GPU-accelerated infrastructure.
Enter NVIDIA Blackwell: Fueling the Reasoning Revolution
Advanced reasoning models like GPT-oss generate tokens at an exponential rate, massively increasing compute demands. Meeting this requires purpose-built “AI factories,” and that’s where the new NVIDIA Blackwell architecture shines. Designed for unprecedented scale, efficiency, and ROI in high-level inference, Blackwell is the engine behind these models’ jaw-dropping performance.
Just how fast? With software optimizations for Blackwell, especially on the monstrous NVIDIA GB200 NVL72 systems, GPT-oss models achieve a staggering 1.5 million tokens per second. That’s massive efficiency for real-world inference!
Blackwell’s secret sauce includes innovations like NVFP4 4-bit precision. This tech enables ultra-efficient, high-accuracy inference while slashing power and memory needs. The result? The ability to deploy trillion-parameter LLMs in real-time, potentially unlocking billions in value.
Jensen Huang Weighs in:
“OpenAI showed the world what could be built on NVIDIA AI – and now they’re advancing innovation in open-source software,” said Jensen Huang, NVIDIA’s founder and CEO. “The GPT-oss models let developers everywhere build on that state-of-the-art open-source foundation, strengthening U.S. technology leadership in AI – all on the world’s largest AI compute infrastructure.”
Open Development for Millions
Accessibility is key. NVIDIA CUDA is the planet’s most widely available computing infrastructure. Whether you’re using the mighty NVIDIA DGX Cloud or an RTX-powered PC or workstation, you can deploy and run these models. With over 450 million CUDA downloads to date, this massive developer community starting today gains access to these latest models, optimized for the NVIDIA stack they already know.
True to the spirit of open-source, OpenAI and NVIDIA collaborated with top framework providers (FlashInfer, Hugging Face, llama.cpp, Ollama, vLLM) alongside NVIDIA’s own TensorRT-LLM and libraries. This means developers can build using their preferred framework.
A Collaboration Rooted in History
The story goes back to 2016 when Jensen Huang himself hand-delivered the first NVIDIA DGX-1 AI supercomputer to OpenAI’s San Francisco HQ. Since then, the two have relentlessly pushed AI boundaries, providing core tech and expertise for massive-scale training runs.
By optimizing OpenAI’s GPT-oss models for NVIDIA Blackwell and RTX GPUs, plus NVIDIA’s vast software stack, they’re enabling faster, more cost-effective AI advancements for over 6.5 million developers across more than 250 countries, using 900+ NVIDIA SDKs and AI models.
With this, OpenAI and NVIDIA are supercharging the global AI ecosystem. With GPT-oss-120b and GPT-oss-20b, powered by CUDA and accelerated by Blackwell, the tools for the next wave of AI innovation are truly open and accessible.
