According to DeepLearning.AI on Twitter, their Retrieval Augmented Generation course offers a comprehensive overview of how large language models (LLMs) generate tokens, the root causes of model hallucinations, and the factuality improvements achieved through retrieval-based grounding. The course also analyzes practical tradeoffs such as prompt length, compute costs, and context window limitations, using Together AI’s production-ready tools as case studies. This curriculum addresses real-world enterprise needs for accurate, cost-effective generative AI, providing valuable insights for businesses seeking to deploy advanced retrieval-augmented solutions and optimize AI-driven workflows (source: DeepLearning.AI Twitter, August 28, 2025).

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).
