ruvLLM Integration Executive Summary

Date: 2025-12-12 Status: DRAFT - Ready for Approval Full Plan: ruvllm-integration-plan.md GitHub Issue: ruvllm-integration-issue.md

TL;DR

Integrate @ruvector/ruvllm v0.2.3 into Agentic QE Fleet to achieve:

• 70% cost reduction ($1,260/month savings)
• 15% quality improvement in test suite generation
• 20% faster test generation via TRM recursive reasoning
• Privacy-first local inference for sensitive codebases

Effort: 133 hours (~5 weeks) ROI: Break-even at 4 months, $40K+ value in first year

---

What is ruvLLM?

@ruvector/ruvllm is a self-learning LLM orchestration system featuring:

1. TRM (Tiny Recursive Models) - 7M parameter network for recursive reasoning

   • 45% accuracy on ARC-AGI-1 (vs 25% for single-pass models)
   • 87.4% Sudoku solving (vs 79.5% for HRM)
   • Iterative refinement (3-7 iterations typical)

2. SONA Adaptive Learning - Continuous improvement without forgetting

   • MicroLoRA (rank 1-2): Instant adaptation for hot paths
   • BaseLoRA (rank 4-16): Long-term consolidation
   • EWC++ (Elastic Weight Consolidation): Prevents catastrophic forgetting

3. Local Inference - Privacy and cost benefits

   • Zero cloud costs for local operations
   • <100ms latency for simple tasks
   • Supports llama-3.2-3b, phi-3-mini, mistral-7b

4. HNSW Vector Memory - Fast similarity search

   • O(log n) search complexity
   • Integration with RuVector distributed database

Why Integrate?

Current Pain Points

High Costs:

• All LLM operations use cloud (Claude: $0.003-$0.03 per 1K tokens)
• Monthly: ~$1,800 for 100K tasks
• No cost optimization for simple tasks

Limited Reasoning:

• Single-pass LLM reasoning
• No iterative refinement
• Poor handling of complex test generation

Static Learning:

• Patterns stored but not improved
• No continuous model adaptation
• Pattern quality degrades over time

Privacy Concerns:

• All code sent to external servers
• Cannot use for sensitive codebases
• Compliance issues for enterprise

Proposed Solution

Cost Optimization:

• 70% of simple tasks routed to local inference (free)
• Cloud only for complex reasoning
• Monthly costs: $1,800 → $540 (70% reduction)

Enhanced Reasoning:

• TRM iterative optimization (3-7 iterations)
• Better edge case discovery
• 15%+ quality improvement

Adaptive Learning:

• SONA continuously improves patterns
• MicroLoRA adapts within 10 iterations
• Pattern quality +5% over 1000 tasks

Privacy-First:

• 100% local mode for sensitive code
• No data sent to cloud
• Enterprise compliance ready

Questions & Concerns

Q1: What if ruvLLM quality is worse than Claude?

• A: HybridRouter automatically falls back to cloud for quality-critical tasks
• Quality gates ensure local only used when confidence >0.8
• User override flags available (--force-cloud)

Q2: What if GPU not available?

• A: CPU fallback supported (2-3x slower but still functional)
• Model quantization reduces memory requirements
• Cloud hybrid mode distributes load

Q3: What if integration takes longer than 5 weeks?

• A: Milestones are incremental - each delivers value independently
• Can pause after M1 (basic local inference) or M2 (TRM reasoning)
• Risk buffer: Estimate is conservative, includes testing time

Q4: What about security and compliance?

• A: Local inference keeps data on-premise (privacy-first)
• No external API calls in local mode
• Security scan included in M5.3 before release

Q5: Can we A/B test before full rollout?

• A: Yes! HybridRouter supports percentage-based routing
• Start with 10% local, gradually increase to 70%
• Monitor metrics, rollback if issues detected
