RAG in 2025: State of the Art and the Road Forward — Tengyu Ma, MongoDB (acq. Voyage AI)
Overview
This talk explores Retrieval Augmented Generation (RAG) as a key technology for enabling large language models (LLMs) to access and utilize proprietary enterprise data. The speaker argues that RAG offers a more efficient, cost-effective, and manageable approach compared to fine-tuning or relying solely on long context windows. The presentation also touches upon the evolution of RAG, advancements in embedding models, and future directions for improving retrieval accuracy and simplifying workflows.
Who should watch
- AI Engineers
- Product Managers
- Builders working with LLMs and proprietary data
- Those seeking to improve the accuracy and efficiency of RAG systems
- Individuals interested in the future of data ingestion for AI
Key takeaways
- RAG is essential for LLMs to access private data without risking leaks, unlike out-of-the-box models.
- Fine-tuning and long context windows are less favored due to difficulties in knowledge management, cost, and efficiency compared to RAG.
- RAG's modularity and similarity to human information retrieval make it a robust and reliable method.
- Significant improvements in retrieval accuracy have been made, with current averages around 80% across many datasets, indicating further headroom for advancement.
- Techniques like Matryoshka learning and quantization offer substantial reductions in vector storage costs, often with minimal impact on accuracy.
- Enhancing RAG involves strategies such as hybrid search, query decomposition, document enrichment, and domain-specific embeddings.
- The future of RAG involves a shift towards more capable models that reduce the need for complex user-implemented "tricks," simplifying workflows.
- Multimodal embeddings and automated context window management are emerging to further streamline the RAG process, handling diverse data formats like screenshots and tables.
Notable quotes
*RAG is very very simple and modularized and very reliable and you know and and also kind of fast and and cheap.*
*I believe that rag will be there forever because this is as I argued in the first slides the kind of like very similar to how humans are using additional large amount of data.*
*I think this model layer will grow and the tricks will be smaller.*
