Feb 1, 2026

Explore the complex distributed system behind ChatGPT, from database architecture and inference engines to scaling strategies and security. Learn how this AI platform handles millions of conversations with remarkable reliability.

Best quote from ChatGPT's Engineering Anatomy

ChatGPT isn't just a single AI model—it's an incredibly complex distributed system that handles billions of tokens daily across global infrastructure. The language model is just one piece of a massive engineering challenge that includes authenticating millions of users, routing requests to thousands of GPUs, and streaming responses with millisecond latency.
