    ChatGPT's Engineering Anatomy

    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.
