TencentDB-Agent-Memory skips vector-store hand-waving and publishes token and accuracy numbers from testing on OpenClaw.
Why now: Covered in the July 13 briefing after the repo picked up 581 stars in a week.
Tencent shipped TencentDB-Agent-Memory, a local long-term memory system for AI agents, per the project's GitHub page. Most memory layers for agents call out to a vector-store API on every recall, adding cost and latency. Tencent says wiring its version into OpenClaw cut token usage up to 61.38% and lifted PersonaMem accuracy from 48% to 76%, per the repo.
The design stacks four tiers into what Tencent calls a semantic pyramid. L0 handles raw conversation. L1 extracts atomic facts, L2 builds scenarios, and L3 compiles a persona profile. A separate symbolic short-term layer condenses tool logs into Mermaid diagram symbols instead of storing raw text. The whole stack runs without any external API dependency, the repo says.
Tencent also reports the change improved task pass rate 51.52% relative to baseline on the same OpenClaw tests, per the repo. The repo doesn't say how the PersonaMem test set was built, or whether Tencent ran it independently.
The 76% score is the headline. The zero-API design is the part that's harder to copy. Vector-store memory needs an API key and a network round trip for every recall. Running locally removes both. That's what competitors will have to match, not the benchmark number.
