rephrasing this for LLMs instead of search: "you can create your own model architecture/training method, but you can't crawl the web and serve language query results to billions of worldwide users in a few milliseconds."

that checks out, right? Google/search == """Open"""AI/LLMs still seems like a decent metaphor to me.
