Vector Space Hackathon 2026 - Qdrant

This post details winning and honorable mention projects from the Qdrant "Think Outside the Bot" hackathon 2026. Winning projects include MemoryAtlas (mental health detection using multi-vector embeddings and payload filtering), Crowd Whisperer (real-time crowd reaction simulation using hybrid vectors and reward formulas), and Synthara (a memory-driven RPG using vector embeddings for narrative persistence). Honorable mentions cover tactical football play search (DejaPlay), DeFi yield product indexing (Cardinal), gardening advice generation (Sprouty), visual anomaly detection (Afterimage), and infrastructure architecture reasoning (Black Swan). The projects showcase diverse applications of Qdrant's vector search capabilities, including multi-vector search, payload filtering, hybrid search, and integration with various AI models and frameworks.
