OntoGr Agent Memory: open-source agent memory where every fact keeps quote, source and time
vm324234 · reddit · 2026-10-27
The author open-sourced OntoGr Agent Memory, a Python library tackling agent memory trust: every extracted fact carries a verbatim quote from its episode. Key features include per-tenant ontologies with human-approved changes, reversible entity resolution, dual time axes (valid time vs system time) for point-in-time queries, contradiction rulings combining rules, an optional model judge, and human override, a hash-chained audit ledger, four-lane retrieval (vector/keyword/entity/graph) fused via RRF into a token-budgeted context block, and support for FalkorDB/Neo4j with optional pgvector/Postgres. The author seeks feedback on the time model and which benchmarks to prioritize.
