AI technology makes daily tasks easier by automating processes such as proofreading and email follow-ups.While LLMs have general uses, specific business applications may require adjustments for optimal performance.RAG combines external knowledge bases with LLMs to enhance accuracy and relevance in responses.RAG acts as an internal search engine, allowing models to retrieve and augment data for improved knowledge.A practical application of RAG is creating an AI-powered PDF Reader Assistant using NLP tools.The process involves preparing a content store, importing necessary modules, and utilizing OpenAI Key or Hugging Face Embedding.In the project, the RAG framework enables the LLM to provide precise responses using additional knowledge sources.By enhancing the LLM with domain-specific data, AI can effectively address queries with specialized content.The RAG process involves receiving user queries, retrieving relevant documents, augmenting context, and generating responses.References to further explore RAG include GitHub, Cloud Google, IBM Think topics, and relevant documentation sources.
