A recent analysis of large language models (LLMs) reveals that while providing additional context can improve performance, it only addresses a portion of the model's limitations. Specifically, context injection, including techniques like retrieval-augmented generation (RAG), effectively fills gaps in factual knowledge, such as identifying speakers or proper nouns. However, it does not enhance the model's core comprehension capacity or its ability to grasp nuances like register or semantic correctness. The study found that these comprehension deficits persist regardless of context, suggesting that model size, rather than external information, is the key factor in improving these aspects. AI
IMPACT Context injection effectively addresses factual knowledge gaps in LLMs but does not improve core comprehension capacity, indicating model size is crucial for deeper understanding.
