Building a simple RAG system for LLMs
This section provides a practical illustration of a simple RAG system, leveraging the robust search capabilities of SerpApi, the semantic understanding of sentence embeddings, and the generative prowess of OpenAI’s GPT-4o model. SerpApi is a web scraping API that provides real-time access to search engine results, offering structured data for Google, Bing, and other platforms without the need for manual scraping.
Through this example, we will explore the fundamental components of a RAG system, including query-based web searching, snippet extraction and ranking, and, ultimately, the generation of a comprehensive answer using a state-of-the-art LLM, highlighting the interplay between these elements in a step-by-step manner.
The code for the simple RAG system we’ll be building contains the following:
- SerpApi: To find relevant web pages based on the user’s query.
- Sentence embeddings: To extract the most relevant...
