A novel memory retrieval system inspired by episodic memory theory achieves state-of-the-art 96.4% top-50 accuracy on the LongMemEval benchmark using Gemini Flash, outperforming larger Pro-based baselines by isolating retrieval quality from model capability.
EviMem combines IRIS for evidence-gap detection and LaceMem for layered memory to improve long-term conversational memory retrieval, achieving higher accuracy on temporal and multi-hop questions with lower latency.
