Frequently Asked Questions
Is RAG still worth learning in 2026?
Yes. RAG remains the most practical way to deliver accurate, auditable answers over private data. It also teaches retrieval, evaluation, and logging skills every AI team uses.
What’s the difference between RAG and an AI agent?
RAG grounds answers with trusted sources; an agent takes actions using tools. Start with RAG for reliability, then layer a small, safe agent with timeouts.
How do I show safety in a portfolio?
Add a “Risks & Mitigations” section: injection checks, I/O filters, secret handling, and a red‑team note. Show one failure you caught and how you fixed it.
