RAG SOTA: I Tested 7 Pipelines and Built SEQUOIA (Open Source)
The article discusses the author's testing of seven retrieval-augmented generation (RAG) configurations to build an open-source system called SEQUOIA. The results revealed that many popular RAG systems underperform in real-world scenarios, with SEQUOIA emerging as the most effective configuration. Key insights include the importance of step-back prompting and the viability of local LLMs for benchmarking.
- ▪The author benchmarked seven RAG configurations against real-world tasks after 20+ hours of compute time.
- ▪SEQUOIA Pro achieved the highest precision and recall among the tested methods, while LightRAG underperformed despite its hype.
- ▪Step-back prompting improved retrieval quality significantly, demonstrating that academic benchmarks do not always reflect production realities.
