Anyone who says it’s relatively easy to go to a different cloud has never led a major migration (I have). That’s kind of part of my day job - cloud consulting.

And if you think it’s hard to move to another LLM you haven’t done a major implementation using an LLM and used LangChain (I have). It abstracts a lot of the work and people can choose which LLM they want to use.

You don’t train your LLM. You use your LLM along with RAG.
