Tencent open-sources Agent Memory: local SQLite memory layer cuts tokens 61%

Tencent has open-sourced Agent Memory, a long-term memory layer for AI agents, sparking Reddit discussion about what it means for hosted-memory startups.
Key points:
- Runs 100% locally on SQLite — no cloud APIs or separate vector database to host
- Reports 61% fewer tokens consumed
- PersonaMem accuracy jumps from 48% to 76%
- Memory is readable and traceable: agents can point back to original conversation logs instead of relying on a black box of embeddings
The poster finds traceability the most interesting part — most memory setups compress everything into vectors, leaving no way to debug wrong recollections. Open questions: how it handles months of memory growth, and the implications for memory startups if it holds up at scale.
