**Can R tame the LLM chaos? Let's find out. 🤖** Two talks. Two live demos. One evening that might change how you think about LLMs in R. Refreshments and networking from 18h00. **Agenda** \~\~\~\~\~\~\~\~\~\~\~\~ \* 16h30 – 16h45 \| Welcome and News \- Handre Williams & Luis de Sousa \* 16h45 – 17h20 \| Handre Williams: **R as the orchestration + statistical validation layer for LLMs** LLMs are powerful but unreliable. R is rigorous but underestimated. This talk explores what happens when you combine the two — using R as the orchestration backbone and statistical validation layer for LLM workflows. Handre will show practical patterns for calling, chaining, and stress-testing LLMs from R, and how classical statistical tools can keep your models honest in production. Includes a live demo. \* 17h20 – 17h55 \| Luis de Sousa: **RAG (Retrieval-Augmented Generation) in R** LLMs hallucinate. The fix? Give them better memory. This talk dives into Retrieval-Augmented Generation (RAG) in R — combining DuckDB's vector search capabilities with R's data ecosystem to ground LLMs in domain-specific knowledge. Luis will show how to build a RAG pipeline from scratch, turning your own data into a knowledge base that makes LLMs actually useful in practice. Includes a live demo. \* 17h55 – 18h00 \| Wrap up\, questions & close \* 18h00 \| Refreshments & networking — continue the conversation in person **Details** \~\~\~\~\~\~\~\~\~\~\~\~ When: 14 April 2026 @ 16h30 to 18h00 (GMT+2) Where: Microsoft Campus in Bryanston, South Africa Location: https://goo.gl/maps/4ffcC3N6T7S2 Keen to speak at a future event?
