Open-model RAG workshop on August 29 covers hybrid retrieval, reranking, benchmarking

A hands-on workshop on August 29, led by Ben Auffarth (AI Consultant and Founder of Chelsea AI Ventures), teaches production retrieval-augmented generation (RAG) using entirely open models with no API calls. The workshop covers hybrid retrieval combining vector and keyword search, reranking to improve chunk relevance, evaluation using RAGAS, guardrails design, and cost and performance benchmarking for open-model deployments.
