Winners of Qdrant Vector Space Hackathon 2026

Detects mental-health spirals before they deepen: each memory is stored in Qdrant as six named vectors (semantic, emotion, prosody and more), a custom transformer reads 14-day emotional sequences, and when trouble looms it retrieves the user's own past recovery as proof they have climbed out before.

Simulates how hundreds of listeners react to a DJ set in real time: every persona lives in Qdrant as a 532-dimension hybrid vector, scored every 15 seconds with drifting preferences, while the crowd's convergence or polarization is projected onto a 2D map.

A dark-fantasy RPG where every player decision becomes a vector 'soul history' — NPCs quote your exact past deeds in dialogue, and story gates unlock based on accumulated episodic memory, all powered by Qdrant Cloud.
