Neural Memory Pro

Drop-in upgrade for Neural Memory — replaces SQLite with a purpose-built spatial database engine.

Why Pro?

Neural Memory (free) uses SQLite — great for getting started, but it hits walls at scale:

Capability	Free (SQLite)	Pro (InfinityDB)
Vector search	Sequential scan	HNSW index, sub-5ms at 1M neurons
Max neurons	~50K practical	2M+ tested, designed for 10M+
Compression	None	5-tier adaptive (up to 89% ratio)
Storage engine	Generic relational DB	Purpose-built for neural graphs
Tiered storage	All in memory	Hot/warm/cold with auto-demotion
Graph traversal	SQL JOINs	Native adjacency + BFS (<1ms depth-3)
MCP tools	52 tools	52 + 3 Pro-exclusive tools
Recall speed	~50ms (small brains)	<5ms p50 at 100K neurons

Installation

# One command — automatically installs neural-memory (free) as dependency
pip install git+https://github.com/AIVN-Foundation/neural-memory-pro.git

That's it. No configuration needed — Pro auto-registers via Python entry_points and upgrades the storage backend transparently.

Verify Installation

nmem version
# neural-memory 4.19.0 (Pro: InfinityDB 0.2.0)

Or in Python:

from neural_memory.plugins import has_pro
print(has_pro())  # True

What You Get

InfinityDB Engine

A custom spatial database engine built specifically for neural memory graphs:

• HNSW Vector Index — Hierarchical Navigable Small World graph for approximate nearest neighbor search. Sub-5ms queries at 1M+ neurons.
• Write-Ahead Log (WAL) — Crash-safe writes with automatic recovery on restart.
• 5-Tier Compression — Adaptive compression pipeline (none → LZ4 → zstd → quantization → cold archive). Automatically selects tier based on access patterns.
• Tiered Storage — Hot neurons stay in memory, warm on SSD, cold compressed. Auto-demotion based on access frequency.
• Native Graph Store — Adjacency lists stored alongside vectors. BFS traversal in <1ms for depth-3.
• Query Planner — Optimizes retrieval strategy based on query type (vector similarity, graph traversal, hybrid).

Pro MCP Tools

Three additional tools available in Claude Code when Pro is installed:

Tool	Description
nmem_cone_query	HNSW cone recall — find all memories within a similarity threshold. Never miss a relevant memory.
nmem_tier_info	Storage tier statistics + trigger demote sweep for cold neurons.
nmem_pro_merge	Smart merge consolidation with dry-run preview. Priority-aware clustering with temporal coherence.

Pro Retrieval Strategies

• Cone Queries — Exhaustive recall via embedding similarity cones. Unlike top-k, cone queries guarantee no relevant memory is missed within a similarity threshold.
• Directional Compression — Multi-axis semantic compression that preserves relationships to multiple concepts simultaneously. Reduces storage while maintaining recall quality.
• Smart Merge — Priority-aware clustering with temporal coherence. Groups related memories and merges them intelligently, respecting priority and recency.

How It Works

1. Install — pip install pulls Pro + free tier as dependency
2. Auto-register — Python entry_points system discovers neural_memory_pro:auto_register
3. Storage upgrade — Free tier's storage/factory.py detects Pro plugin → uses InfinityDB instead of SQLite
4. Transparent — All 52 free MCP tools work unchanged. 3 Pro tools are added automatically.
5. Fallback — If Pro is uninstalled, free tier falls back to SQLite with zero errors
