Ask HN: Is RAG the Future of LLMs?

The author believes that RAG (Retrieval-Augmented Generation) is a temporary solution until infinite context can be virtually figured out. They compare the context of Language Models (LLM) to cache levels, where the first level is small but fast (similar to working memory), and subsequent levels are larger but slower. They view RAG as a flawed version of attention mechanisms, used to focus on relevant documents.

However, the author points out that RAG systems are not designed to minimize loss, but rather operate on a similarity score. They caution that this is their personal opinion and they could potentially be incorrect.

Key takeaways
