This is the first time I heard this term, and when I Google search "LLM developer" in an incognito tab, different device, this article is one of the first results.
Seems like we should first establish what exactly is an LLM developer.
> When I was at Google, there was a document put together by Jeff Dean, the legendary engineer, called Numbers every Engineer should know.
The personal plug and appeal to authority of "When I was a Google" is unnecessary. "Numbers every Engineer should know" is public and literally linked there. It's a weird way to start a engineering blog post and makes it feel like marketing of one's resume. Then again, I guess that's what most of these engineering blog posts are nowadays.
Indeed Jeff Dean is a legend and needing to add the "legendary engineer" qualifier detracts from this point. Let these things speak for themselves.
