The claim that RAG is dead is obviously wrong.
The internet is full of blog posts about this. That doesn't mean they're actually good - I'd love to be pointed at one that has proven itself useful for someone (and definitely isn't just LLM blog-spam).
I don't care if it's trivial to fine-tune and get crap results - I care about fine-tuning where the result was worth the effort.
For the record, my favourite guide to fine-tuning is the section of this Jeremy Howard video that shows how to train a text-to-SQL model: https://www.youtube.com/watch?v=jkrNMKz9pWU&t=4850s
The person asked for citations, leave it be, stop dudexplaining how Internet works for you please.
I call bs on your 2 comments.
Even when people sincerely ask for a citation on a debatable topic, on an internet forum, it's effectively saying "I won't be hear any opinion that doesn't match my own unless it's as water tight as a law of physics". Another form of this is "show me the data".
