Hy-Memory-30B-A3B: Attributed Reinforcement Learning for Long-Term Memory Writing
Hy-Memory-30B-A3B is a compact long-term-memory writer trained across Mem0, MemOS, and Hy-Memory to decide what to retain and how to update persistent memory. It reported top results on all evaluated memory harnesses, including held-out EverMemOS, with a higher macro average than Claude Opus 5.
