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. ## Full article daily.dev links to this article rather than hosting it.
