Wed 7 Oct 2026 · 18:00–22:00 CEST Whether you’re a seasoned ML engineer, a new AI product owner or simply curious about vector search, this meetup will cover the fundamentals through to how AI-native companies manage vector search at scale. Three talks from experts in the industry and a chance to network with like-minded folks. Hosted at Criteo's Paris office, co-organised with the Criteo engineering team. Talks are in English. What you’ll hear about What a vector index is really doing, and why recall drops where it does Agentic retrieval vs. a good index: the honest trade-offs in latency, cost, and quality Scaling a production index: the design decisions you only discover after launch Embeddings, chunking, and the latest techniques to improve quality while reducing cost Agenda 18:00 — Doors open.
