Rapidly scaling online storage to serve over 1 billion ChatGPT users (Part II)
Learn how OpenAI scaled Habitat with reliable multi-tenancy, global caching, and Azure Cosmos DB to deliver 12× faster reads for ChatGPT.
How we optimized Azure Cosmos DB in our application storage platform, Habitat, to manage unprecedented growth.

All OpenAI products require fast, reliable access to data, provided by our storage platform, Habitat. It has to respond in milliseconds to over 1 billion users across 40 geographic regions. Our infrastructure faced an extraordinary challenge: supporting explosive growth and new use cases while continuing to improve reliability, performance, and product developer velocity. Solving that challenge required rethinking how our online storage platform was designed and operated. We constantly evaluated tradeoffs, following the pattern of: first become reliable enough for mission-critical product traffic, then fast enough for global users, and, finally, to deftly operate at massive scale.
