Advancements in Retrieval Augmented Generation (RAG)
Retrieval Augmented Generation (RAG) is becoming increasingly important in AI as it addresses the issue of hallucinations in large language models (LLMs). The distinction between retrieval and generation is emphasized, with models relying on a solid context to produce accurate responses. Benchmarks from models like O3 and Gemini 2.0 show significant improvements in hallucination rates, achieving as low as 0.8% in some cases. However, there remains a consensus that further reducing hallucinations to a 0.5% threshold may be difficult due to the probabilistic nature of these models.
