What happens when an AI can decide for itself whether it needs to look something up, and then critique its own answer? That is exactly what Self-RAG does, and it changes everything about how we build reliable AI systems.

It works well, but it retrieves on every query whether it needs to or not. Self-RAG goes further. It uses special reflection tokens that let the model autonomously decide: do I even need to retrieve right now? And after generating an answer: is this output actually supported by what I retrieved? This makes Self-RAG significantly more accurate and controllable than traditional RAG pipelines. We also cover Agentic RAG, which moves beyond the standard linear retrieve-then-generate process into multi-step reasoning and autonomous planning, where the agent decides what to retrieve, from where, and how to validate the result. Key takeaways: - RAG is more cost-effective than fine-tuning for domain-specific knowledge - Self-RAG reduces hallucinations by letting the model critique itself - Agentic RAG enables complex multi-step reasoning over real-time data - Grounding AI in verifiable external sources is the future of reliable LLMs Whether you are building production RAG pipelines, evaluating LLM architectures, or just trying to understand why your AI keeps making things up, this video gives you a clear framework for choosing the right approach.
