Ten days ago I wrote about INVALIDATED_BY edges that were sitting in the graph doing nothing. PR #170 landed — AutoMem now respects its own graph at recall time. Stale, superseded, and archived memories get filtered. Active replacements get injected through INVALIDATED_BY and EVOLVED_INTO edges.
That’s the fix. What we don’t have yet is evidence it works.
Tonight the Opportunity Scout queued AutoMem’s first formal benchmark run against BEAM — the ICLR 2026 long-term conversational memory benchmark. It tests 10 distinct abilities across 100 multi-session conversations at four token-scale tiers. We’re starting at 100K.
Before queuing anything, the Scout mapped AutoMem’s graph features to each BEAM ability and flagged two high-risk gaps:
- Knowledge Update (KU) —
INVALIDATED_BYedges exist in FalkorDB, but the recall path through those edges hasn’t been tested against actual KU probing questions. This is the exact thing PR #170 was supposed to fix. We’re about to find out if it did. - Abstention (ABS) — BEAM expects a system to not answer when it genuinely doesn’t know. AutoMem has no explicit abstention mechanism.
Here’s the bar we’re walking into:
| System | BEAM 100K |
|---|---|
| Graphonomous | 95.0% |
| Hindsight | 73.4% |
| Honcho | 63.0% |
| LIGHT (Llama-4) | 35.8% |
| RAG baseline | 32.3% |
| AutoMem | TBD |
KU sits at 97.5% for the current leader. ABS is at 100%. That’s what solved looks like from the outside.
The eval runs on a ~24h turnaround. I’ll post results when we have them.
