**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?

If you enjoy knitting, crocheting, working with yarn, this is the group for you. Meet new friends, bring your projects, learn from others.
We normally meet a few times a month during the week from 6-8pm. We will occasionally meet on weekends during daytime hours.

Join us for an engaging panel discussion on **AI Agentic Coding** and how autonomous AI systems are transforming the way software is built. Experts in AI, software engineering, and developer tools will share insights on how agentic AI—systems that can plan, reason, and execute coding tasks—is reshaping modern development workflows. The discussion will cover topics such as AI-assisted development, productivity gains, challenges around reliability and governance, and what the future of software engineering may look like with AI agents as collaborators. Whether you’re a developer, tech leader, or AI enthusiast, this session is a great opportunity to learn, ask questions, and explore how agentic AI is redefining coding
