Hy-Memory gives long-running agents a structured memory layer

Context

Tencent's Hy-Memory organizes an assistant's conversation history into material it can reuse later. The project documentation describes a fast path that records conversations and extracts facts, preferences and summaries, plus a slower background process that develops higher-level interpretations.

The system also describes merging repeated facts and updating preferences when newer information conflicts with an older record. Its intended benefit is continuity: an assistant can retain a current account of the user across interactions, instead of accumulating every old statement as equally relevant. That is the mechanism behind the memory plugin's promise of longer-term collaboration.
