Logica Mind — LoCoMo Benchmark Results
Reproducible accuracy results for Logica Mind (open-source agent memory) on LoCoMo, alongside published numbers for other memory systems — all under the same protocol as the Mem0 paper (arXiv:2504.19413): gpt-4o-mini as both answerer and judge, adversarial category excluded, 1,540 scored questions.

Logica Mind's full pipeline is the best-scoring memory system in the published protocol. Full methodology, per-category breakdown, the published negative result, and one-command reproduction: BENCHMARKS.md.
Per-category accuracy (full pipeline)
| Category | Logica Mind | Mem0 (published) |
|---|---|---|
| single-hop | 83.5% | 67.1% |
| temporal | 70.7% | 55.5% |
| multi-hop | 53.2% | 51.2% |
| open-domain | 37.0% | 72.9% |
Reproduce
pip install logica-mind

Every competing number links to its primary source; nothing is estimated. Where sources conflict (the public Mem0×Zep dispute), both sides are shown in BENCHMARKS.md.
