OpenAI described the multi-tenant architecture, global cache and use of Azure Cosmos DB in the Habitat storage system. According to the company, the solution delivered a twelvefold improvement in read performance for ChatGPT.

OpenAI published another installment of its case study on scaling the Habitat storage platform. It described a multi-tenant architecture, a global cache and the use of Azure Cosmos DB. According to OpenAI, the solution delivered a twelvefold improvement in read performance for ChatGPT.

According to OpenAI, Habitat began as a Python library and gradually evolved into a globally distributed storage system. The company says it serves a billion ChatGPT users and processes 22 million requests per second. Details are available in the source article.

What changed

Why it matters

The case study gives teams designing large-scale storage systems a concrete architecture to assess when addressing shared workloads and read performance. The reported improvement concerns reads from storage, not a demonstrated improvement in the time taken to produce complete ChatGPT responses.
