RAG course: your questions

06 / Answers

What is RAG?

RAG (Retrieval-Augmented Generation) lets a language model answer from your own documents and databases: the system first retrieves the relevant passages, then the LLM generates its answer based on them.

Is the RAG course online?

Yes, 100% online: 5 days (35 hours) of live sessions, hands-on labs and replays. You leave with the notebooks, the code repositories of your final project and a certificate.

What level do I need?

Intermediate to advanced. The course is taught in Python, with LangChain, LlamaIndex and FastAPI.

Which tools will we use?

LangChain, LlamaIndex, the OpenAI and Anthropic APIs, the Pinecone, Qdrant and pgvector vector databases, FastAPI, Prefect for orchestration, Ragas and LangSmith for evaluation.

RAG or AI agents: what is the difference?

RAG gives an LLM access to your knowledge; an AI agent plans and carries out actions in your tools. The two are often combined: see the AI Agents & MCP course.

How can the course be funded?

Jobseekers registered in France can apply for AIF funding from France Travail. Companies can fund it through their skills development plan.
