OpenAI

OpenAI runs large GPU superclusters and Kubernetes-based orchestration across Azure and its own data centers in a hybrid setup, with Azure as the primary cloud and custom HPC clusters (e.g., Stargate) for training and serving frontier models.[15][16][19] Core application and API workloads use relational stores like PostgreSQL for accounts/settings and globally scalable databases such as Azure Cosmos DB plus Kafka streams for high-volume conversation, analytics, and event data.[1][8][12]

FAQ

Does OpenAI use a foundational AI model?

OpenAI uses GPT-4 class frontier models (e.g., GPT-4 family), GPT-4o and successor ChatGPT models (Native (own / self-hosted weights)).

What cloud does OpenAI run on?

OpenAI runs on Hybrid.

What database does OpenAI use?

OpenAI uses Azure Cosmos DB, PostgreSQL, Blob/Object Storage (e.g., Azure Blob), Kafka (for event/log streaming).

How close does OpenAI run to the foundational model?

OpenAI is Native (own / self-hosted weights) — close to the metal, so cheaper tokens and more control over outputs.
