OpenAI Uses NVIDIA GB200 NVL72 for Model Training as Rubin Deployments Expand
NVIDIA has identified OpenAI as one of its Lighthouse model builders using the GB200 NVL72 rack-scale system at data-center scale for next-generation model training and production inference.

OpenAI has been identified as one of NVIDIA's Lighthouse model builders utilizing the GB200 NVL72 rack-scale system for next-generation model training and production inference. This confirmation places OpenAI's infrastructure strategy within NVIDIA's rack-scale approach to AI computing, which combines compute, networking, and systems design to support model development and deployment.
The source does not provide a direct confirmation of OpenAI's use of NVIDIA's Vera Rubin platform, which is a separate rack-scale AI factory architecture. The confirmation of OpenAI's GB200 NVL72 usage, however, indicates that NVIDIA views OpenAI as a key user of this integrated system in the transition from model training into production inference.
