Frequently Asked Questions

What are AI agents?

AI agents are autonomous software systems powered by large language models (LLMs) that can perceive their environment, make decisions, and take actions to achieve specific goals. Unlike simple chatbots, AI agents can use tools, access external data, maintain memory across interactions, and chain multiple reasoning steps together to solve complex problems.

What is RAG (Retrieval-Augmented Generation)?

RAG (Retrieval-Augmented Generation) is a technique that enhances LLM responses by retrieving relevant information from external knowledge bases before generating an answer. It combines a retrieval system (typically using vector databases and embeddings) with a generative model, allowing AI applications to provide accurate, up-to-date answers grounded in specific documents or data sources.

How do vector databases work?

Vector databases store data as high-dimensional numerical vectors (embeddings) and enable similarity search using distance metrics like cosine similarity. When you query a vector database, it finds the most semantically similar vectors to your query, making it ideal for RAG pipelines, recommendation systems, and semantic search. Popular vector databases include Pinecone, ChromaDB, Weaviate, and Qdrant.

What is the difference between fine-tuning and RAG?

Fine-tuning modifies the LLM's weights by training it on domain-specific data, permanently embedding knowledge into the model. RAG keeps the model unchanged and instead retrieves relevant context at query time from external sources. RAG is preferred when knowledge changes frequently, you need source attribution, or you want to avoid the cost of fine-tuning. Fine-tuning is better for teaching the model new behaviors, styles, or specialized reasoning patterns.
