Someone just reverse-engineered how OpenAI's new Intelligent UI actually works.

And the architecture is fascinating.

ChatGPT generates working interfaces using:

- A custom UI language (DIL) - Server-side compilation - A sandboxed runtime - ~70 native UI components - Interactions without additional AI calls

The full engineering breakdown is worth reading.

ChatGPT launched their version of Generative UI yesterday. We took it apart tldr; the agent never write raw code. It emits DIL (a new language), the server compiles and streams it, the client renders it using a component set so that it feels native https://t.co/EzfM43fgkf
