    RAG: 0-100km/h in 30 mins

    Learn from Walter

    " RAG helps to avoid hallucination because I already provide the truth and the answer, in my context. So I don't need to rely on the model hallucinating because it won't be doing that because it already has the answer."

    You've barely got your mind around LLMs like ChatGPT and now you see the term RAG everywhere. What is a RAG in layman's terms, why should you care and what can and can't it do?


    This talk takes the attendee from 0 to RAG in simple words, explaining some of the concepts you'll see and giving some clear examples of what makes it tick. We'll cover things like embedding models and vector databases as well as context retrievers and prompt templates. After this talk you'll have a better idea about RAG and why it's exciting (it is, I promise!)
