According to DeepLearning.AI, the ability of large language models (LLMs) to make sense of retrieved context in Retrieval Augmented Generation (RAG) systems is rooted in the transformer architecture. During a lesson from the RAG course, DeepLearning.AI explains that LLMs process augmented prompts by leveraging token embeddings, positional vectors, and multi-head attention mechanisms. This process allows LLMs to integrate external information with contextual relevance, improving the accuracy and efficiency of AI-driven content generation. Understanding these transformer components is essential for organizations aiming to optimize RAG pipelines and unlock new business opportunities in AI-powered search, knowledge management, and enterprise solutions (source: DeepLearning.AI Twitter, July 31, 2025).
