Tencent Open-Sources TencentDB Agent Memory: A 4-Tier Local Memory Pipeline for AI Agents
Quick Answer
Tencent has open-sourced TencentDB Agent Memory, a local memory system for AI agents featuring a 4-tier memory pipeline.
Quick Take
Tencent has open-sourced TencentDB , a local memory system for AI agents featuring a 4-tier memory pipeline. It achieves a 61.38% token reduction and a 51.52% pass-rate gain on WideSearch, with PersonaMem accuracy improving from 48% to 76%. The system integrates symbolic short-term memory with long-term memory structures and is available as an OpenClaw plugin and Hermes Docker image.
Key Points
- TencentDB Agent Memory is released under the MIT license.
- The memory system features a 4-tier pyramid: L0 to L3.
- It runs on local SQLite and uses hybrid BM25 + vector retrieval.
- OpenClaw benchmarks show significant improvements in token reduction and accuracy.
- Available as an OpenClaw plugin and Hermes Docker image.
Article Excerpt
From source RSS / original summaryTencent has open-sourced TencentDB , a fully local memory system for AI agents released under the MIT license. The project pairs symbolic short-term memory, which offloads verbose tool logs into a compact Mermaid task canvas, with a 4-tier long-term memory pyramid (L0 Conversation → L1 Atom → L2 Scenario → L3 Persona). It ships as an OpenClaw plugin and a Hermes Docker image, runs on local SQLite + sqlite-vec by default, and uses hybrid BM25 + vector retrieval with RRF fusion.
Tencent's own benchmarks report a 61. 38% token reduction and 51. 52% relative pass-rate gain on WideSearch with OpenClaw, alongside PersonaMem accuracy moving from 48% to 76%.
