Baidu, a leading AI company, highlights the importance of a balanced approach in artificial intelligence (AI) that can produce valid and fast responses. Retrieval-augmented generation (RAG), which involves having a language model send a request to an external data source for authoritative information, is emerging as a pivotal technology in the battle between large language models (LLMs). RAG helps reduce false assertions, or "hallucinations, " by LLMs. Commercial vendors like Elastic and Pinecone are developing programs that allow companies to connect to databases and retrieve accurate answers. The use of RAG is expected to become commonplace in all AI models, necessitating a closer integration between generative AI training and RAG techniques.

However, challenges such as conflicting information and limited context handling need to be addressed in LLM designs. Researchers are studying failure cases and proposing training methods, like INFO-RAG, to improve LLM accuracy with RAG data. RAG also presents an alternative to fine-tuning and function calling methods, potentially guiding LLM development towards smaller models. The road ahead involves adapting AI models to effectively incorporate RAG-based knowledge and creating RAG-aware LLMs customized to specific domains or companies.
