Winners That Put Memory at the Center

MemoryAtlas stores each memory as six named vectors — semantic, emotional, prosodic and more — then reads fourteen-day emotional sequences. Crowd Whisperer holds every listener as a 532-dimension vector and rescores drifting taste every fifteen seconds. Synthara accumulates player decisions as a 'soul history' that NPCs quote back. RoboBank banks robot action sequences with safety labels and picks the next move by nearest-neighbor retrieval.

What unites them is that none use the vector database merely to make search faster. All eight design the structure of memory itself: what constitutes one vector, which axes to separate, how long a window counts as one sequence. That design decision is the substance of the project. As Spatio-Temporal NPCs showed by running on roughly 3GB of local VRAM, these compete on structure rather than scale.

Takeaway: at a vector-database event, 'we do RAG' is not a differentiator, because most entrants will do exactly that. Ask instead whether your subject can be decomposed into several axes stored as separate vectors, or read as a sequence over time. Memory design is easy to explain and its structure lands quickly with judges.
