Vector Space Day 2025, hosted by Qdrant, is scheduled for September 26, 2025, at the Colosseum in Berlin, offering a full-day event dedicated to exploring advancements in retrieval, vector search infrastructure, and agentic AI. The event will feature deep-dives, lightning talks, and panels, focusing on AI infrastructure, search relevance, semantic retrieval, and the future of AI agents. Attendees can expect to engage in discussions on topics such as vector databases, AI memory, RAG pipelines, and hybrid search systems while also having the opportunity to network with developers reshaping AI systems. The event includes an after-party for further networking and discussions, and a global hackathon, "Think Outside the Bot," which challenged participants to innovate with vector search, concluded prior to the event. Key partners like AWS, Microsoft, and Neo4j underscore the growing momentum in vector search and retrieval-augmented generation systems, emphasizing the event's significance in the AI community.
