SuperLocalMemory V3

The first local-only AI memory to break 74% retrieval on LoCoMo.
No cloud. No APIs. No data leaves your machine.

+16pp vs Mem0 (zero cloud) · 85% Open-Domain (best of any system) · EU AI Act Ready

Why SuperLocalMemory?

Every major AI memory system — Mem0, Zep, Letta, EverMemOS — sends your data to cloud LLMs for core operations. That means latency on every query, cost on every interaction, and after August 2, 2026, a compliance problem under the EU AI Act.

SuperLocalMemory V3 takes a different approach: mathematics instead of cloud compute. Three techniques from differential geometry, algebraic topology, and stochastic analysis replace the work that other systems need LLMs to do — similarity scoring, contradiction detection, and lifecycle management. The result is an agent memory that runs entirely on your machine, on CPU, with no API keys, and still outperforms funded alternatives.

The numbers (evaluated on LoCoMo, the standard long-conversation memory benchmark):

System	Score	Cloud Required	Open Source	Funding
EverMemOS	92.3%	Yes	No	—
Hindsight	89.6%	Yes	No	—
SLM V3 Mode C	87.7%	Optional	Yes (MIT)	$0
Zep v3	85.2%	Yes	Deprecated	$35M
SLM V3 Mode A	74.8%	No	Yes (MIT)	$0
Mem0	64.2%	Yes	Partial	$24M

Mode A scores 74.8% with zero cloud dependency — outperforming Mem0 by 16 percentage points without a single API call. On open-domain questions, Mode A scores 85.0% — the highest of any system in the evaluation, including cloud-powered ones. Mode C reaches 87.7%, matching enterprise cloud systems.

Mathematical layers contribute +12.7 percentage points on average across 6 conversations (n=832 questions), with up to +19.9pp on the most challenging dialogues. This isn't more compute — it's better math.

Upgrading from V2 (2.8.6)? V3 is a complete architectural reinvention — new mathematical engine, new retrieval pipeline, new storage schema. Your existing data is preserved but requires migration. After installing V3, run slm migrate to upgrade your data. Read the Migration Guide before upgrading. Backup is created automatically.

Three Operating Modes

Mode	What	Cloud?	EU AI Act	Best For
A	Local Guardian	None	Compliant	Privacy-first, air-gapped, enterprise
B	Smart Local	Local only (Ollama)	Compliant	Better answers, data stays local
C	Full Power	Cloud LLM	Partial	Maximum accuracy, research

slm mode a   # Zero-cloud (default)
slm mode b   # Local Ollama
slm mode c   # Cloud LLM

Mode A is the only agent memory that operates with zero cloud dependency while achieving competitive retrieval accuracy on a standard benchmark. All data stays on your device. No API keys. No GPU. Runs on 2 vCPUs + 4GB RAM.

Mathematical Foundations

Three novel contributions replace cloud LLM dependency with mathematical guarantees:

Fisher-Rao Retrieval Metric — Similarity scoring derived from the Fisher information structure of diagonal Gaussian families. Graduated ramp from cosine to geodesic distance over the first 10 accesses. The first application of information geometry to agent memory retrieval.
Sheaf Cohomology for Consistency — Algebraic topology detects contradictions by computing coboundary norms on the knowledge graph. The first algebraic guarantee for contradiction detection in agent memory.
Riemannian Langevin Lifecycle — Memory positions evolve on the Poincare ball via discretized Langevin SDE. Frequently accessed memories stay active; neglected memories self-archive. No hardcoded thresholds.

These three layers collectively yield +12.7pp average improvement over the engineering-only baseline, with the Fisher metric alone contributing +10.8pp on the hardest conversations.

Benchmarks

Evaluated on LoCoMo — 10 multi-session conversations, 1,986 total questions, 4 scored categories.

Mode A (Zero-Cloud, 10 Conversations, 1,276 Questions)

Category	Score	vs. Mem0 (64.2%)
Single-Hop	72.0%	+3.0pp
Multi-Hop	70.3%	+8.6pp
Temporal	80.0%	+21.7pp
Open-Domain	85.0%	+35.0pp
Aggregate	74.8%	+10.6pp

Mode A achieves 85.0% on open-domain questions — the highest of any system in the evaluation, including cloud-powered ones.

Math Layer Impact (6 Conversations, n=832)

Conversation	With Math	Without	Delta
Easiest	78.5%	71.2%	+7.3pp
Hardest	64.2%	44.3%	+19.9pp
Average	71.7%	58.9%	+12.7pp

Mathematical layers help most where heuristic methods struggle — the harder the conversation, the bigger the improvement.

Ablation (What Each Component Contributes)

Removed	Impact
Cross-encoder reranking	-30.7pp
Fisher-Rao metric	-10.8pp
All math layers	-7.6pp
BM25 channel	-6.5pp
Sheaf consistency	-1.7pp
Entity graph	-1.0pp

EU AI Act Compliance

The EU AI Act (Regulation 2024/1689) takes full effect August 2, 2026. Every AI memory system that sends personal data to cloud LLMs for core operations has a compliance question to answer.

Requirement	Mode A	Mode B	Mode C
Data sovereignty (Art. 10)	Pass	Pass	Requires DPA
Right to erasure (GDPR Art. 17)	Pass	Pass	Pass
Transparency (Art. 13)	Pass	Pass	Pass
No network calls during memory ops	Yes	Yes	No

To the best of our knowledge, no existing agent memory system addresses EU AI Act compliance. Modes A and B pass all checks by architectural design — no personal data leaves the device during any memory operation.

Built-in compliance tools: GDPR Article 15/17 export + complete erasure, tamper-proof SHA-256 audit chain, data provenance tracking, ABAC policy enforcement.
