Under this new $38 billion agreement, which will have continued growth over the next seven years, OpenAI said it is accessing AWS compute comprising hundreds of thousands of state-of-the-art NVIDIA GPUs, with the ability to expand to tens of millions of CPUs to rapidly scale agentic workloads.

"AWS has unusual experience running large-scale AI infrastructure securely, reliably, and at scale–with clusters topping 500K chips," read the statement issued by OpenAI.

The statement said AWS's leadership in cloud infrastructure combined with OpenAI's pioneering advancements in generative AI will help millions of users continue to get value from ChatGPT.

OpenAI will immediately start utilizing AWS compute as part of this partnership, with all capacity targeted to be deployed before the end of 2026, and the ability to expand further into 2027 and beyond.

"The infrastructure deployment that AWS is building for OpenAI features a sophisticated architectural design optimized for maximum AI processing efficiency and performance," the statement said.

Clustering the NVIDIA GPUs—both GB200s and GB300s—via Amazon EC2 UltraServers on the same network enables low-latency performance across interconnected systems, allowing OpenAI to efficiently run workloads with optimal performance.

The clusters are designed to support various workloads, from serving inference for ChatGPT to training next generation models, with the flexibility to adapt to OpenAI's evolving needs.

Our partnership with AWS strengthens the broad compute ecosystem: Sam Altman

“Scaling frontier AI requires massive, reliable compute," said OpenAI co-founder and CEO Sam Altman. “Our partnership with AWS strengthens the broad compute ecosystem that will power this next era and bring advanced AI to everyone.”

“As OpenAI continues to push the boundaries of what's possible, AWS's best-in-class infrastructure will serve as a backbone for their AI ambitions,” said Matt Garman, CEO of AWS. “The breadth and immediate availability of optimized compute demonstrates why AWS is uniquely positioned to support OpenAI's vast AI workloads."
