Comparing Continued Pretraining to RAG (accuracy and performance)

📌 Mostly as a fun experiment I wanted to do a quick comparison of performance and accuracy between a CPT trained QWEN 3.5 4B model and a RAG implementation against the base model. The point of this exercise is mostly to measure the performance benefit of internalizing the knowledge vs doing reasoning on-the-fly. Sharing my findings here in case anyone is interested: https://www.teachmecoolstuff.com/viewarticle/comparing-rag-and-continued-pretraining-of-llms submitted by /u/funJS [link] ...
