Hy-Memory Writer Matrix - Mem0: leaderboard
Long-term memory writing: the listed model is the memory writer inside an unchanged memory framework; a frozen answer model and judge are shared. Each harness score is the equal-weight mean of six metrics (LoCoMo judge, LongMemEval, PersonaMem-v2, Travel SPS, Shopping PS, Code Memory Bench) on fixed deterministic 20% benchmark subsamples. Mem0 harness (trained on). Checkpoint identifiers are omitted by the paper. Hy3 is the paper's Hy3 flagship label (reasoning mode unspecified); Hy3-A3B Base is the paper's label for the Hy3-30B-A3B instruction-tuned starting checkpoint of Hy-Memory-30B-A3B. Metric: Six-metric mean score (%). Higher is better. Source: https://arxiv.org/html/2610.22196v1
Metric: Six-metric mean score (%). Source: arxiv.org. Saturation forecast: Around 2031. 7 models tracked.
