Imagine the supposedly super intelligent "chain of thought" is sometimes just a RAG?
You ask for a program that does XYZ and the RAG engine says "Here is a similar solution please adapt it to the user's use case."
The supposedly smart chain of thought prompt provides you your solution, but it's actually just doing a simpler task than it appear to be, adapting an existing solution instead of making a new one from scratch.
Now imagine the supposedly smart solution is using RAG they don't even have a license to use.
Either scenario would give them a good reason to try to keep it secret.
