Jev-Mem paper: a fast scorer makes agent memory building 6.6x faster on LoCoMo

rohanpaul_ai · x · 2026-10-25

A UT Dallas paper introduces Jev-Mem, an agentic memory architecture that offloads small routing/scoring/stopping decisions from the LLM to a fast batched scorer called Jev, calling the LLM only for final answer synthesis. On the LoCoMo long-conversation benchmark it scores 0.777 vs 0.700 for the best baseline, builds memory in 158s vs 1,044s for the fastest rival (6.6x speedup), and answers in 0.93s vs 1.47s. Transferable tip: replace LLM calls in memory pipelines with fast classifiers and save the LLM for answers. Code is public.
