Where it is mentioned most
Each row divides by that role's postings in this edition, highest share first.
Postings in 10 role families mention RAG in this edition.
In 2 of the 8 role families with a page of their own, at least one posting in five mentions RAG: LLM / NLP Engineer 53.7%, AI Engineer 24.6%.
RAG is more concentrated in LLM / NLP Engineer postings (53.7%) than across all core AI postings (18.9%): at least twice the overall share.
RAG is in LLM applications: a framework, LLM or domain signal. Read it together with the foundation and production skills that appear with it below.
How the readings are made: "more concentrated than overall" means that in a role family with a page of its own, at least 10 postings mention the skill and its share is at least 2 times its share of all core AI postings; "common" means at least 20% of a role's postings mention it. They describe the postings open in this edition, not a trend.
