Over 10,000 NVIDIANs across functions got early access to OpenAI’s latest frontier model, GPT-5.5. The results, one engineer said, are “blowing my mind.”

The NVIDIA Developer Blog provides developers with a  knowledge on GPU computing, AI, and deep learning, offering tutorials, code samples, and real-world applications of NVIDIA technologies. From optimizing GPU-accelerated algorithms to implementing  AI models, developers can learn practical techniques and strategies for harnessing the power of NVIDIA GPUs in their projects. Moreover, the blog highlights advancements in GPU architectures, CUDA programming, and GPU-accelerated libraries, empowering developers to stay at the forefront of GPU computing innovation.

NVIDIA has deployed OpenAI's new GPT-5.5 model through the Codex agentic coding app to over 10,000 employees across all departments. The model runs on NVIDIA GB200 NVL72 rack-scale systems, which deliver 35x lower cost per million tokens and 50x higher token output per second per megawatt versus prior-generation hardware. NVIDIA IT provisioned dedicated cloud VMs for each employee with a zero-data retention policy and read-only production access for security. The rollout reflects a decade-long NVIDIA-OpenAI partnership that began with Jensen Huang hand-delivering the first DGX-1 to OpenAI in 2016, and now includes OpenAI committing to deploy over 10 gigawatts of NVIDIA systems for future AI infrastructure.
