LlamaIndex

LlamaIndex is an open source framework specialized in connecting LLMs with business data. It excels in creating RAG systems that allow AI to respond based on internal documents.

AI Fundamentals

RAG (Retrieval-Augmented Generation)

RAG is a technique that combines information retrieval from a document base with AI text generation. Instead of relying solely on the model's knowledge, the system first searches for relevant documents (manuals, FAQs, contracts) and then generates responses based on those documents. It is the most effective approach for creating reliable business chatbots.

AI Fundamentals

AI Agent

An AI agent is an autonomous system that can plan actions, use tools (APIs, databases, email) and complete complex tasks without continuous human intervention. Unlike a chatbot that answers questions, an agent can execute a complete workflow: analyze an order, check availability, generate a quote, and send it to the client.
