Building a RAG Chatbot Using Langflow and Upstash Vector

The blog post provides a step-by-step guide on building a Retrieval-Augmented Generation (RAG) chatbot using Langflow and Upstash Vector. It explains how to set up the project using Langflow, which simplifies complex large language model (LLM) workflows with its graph-based structure and various integrations, including Upstash Vector for vector-based search. The tutorial describes creating a basic OpenAI chatbot, adding an API key securely, and setting up an Upstash Vector index to store and retrieve data. It further explains enhancing the chatbot by integrating vector search capabilities to retrieve relevant context from the index based on user input, thereby improving the quality of responses generated by OpenAI's gpt-4o-mini model. The blog concludes by emphasizing the chatbot's improved accuracy and relevance due to the use of vector search and offers additional resources for further exploration.
