## Summary

Tencent Hunyuan has released **Hy-Memory-30B-A3B**, a lightweight model (~3B active parameters) designed to manage long-term memory in external frameworks like **Mem0**, **MemOS**, and **Hy-Memory**. It replaces general-purpose LLMs in these systems, deciding what data to store, how to represent it, and how to update persistent memory banks. The model was trained in two stages—**Memory On-Policy Distillation (OPD)** followed by **Attributed Memory Reinforcement Learning**—and achieves cross-harness macro-average scores on a fixed 20% benchmark matrix, including **EverMemOS**, which was held out from training.

Tencent provides deployment instructions via **vLLM (v0.31.0)** with an OpenAI-compatible API. The model is available on **Hugging Face** with weights, configuration, and a model card. Benchmarking details, including six metrics (LoCoMo Judge, LongMemEval, PersonaMem-v2, Travel SPS, Shopping PS, and Code Memory Bench), are documented in an accompanying **arXiv report**. The framework code and utilities are open-source on **GitHub**.

## Key points

- Hy-Memory-30B-A3B (~3B params) replaces general-purpose LLMs in memory frameworks like Mem0 and MemOS
- Trained via OPD and reinforcement learning, tested on EverMemOS (held-out benchmark)
- Deployable via vLLM (v0.31.0) with OpenAI-compatible API; weights on Hugging Face

## Why it matters

This model improves persistent memory systems for chat, coding, and task-specific scenarios, reducing reliance on retrieval-augmented generation. Useful for developers building memory-aware AI applications.
