Quick Start | RLM | Training | Models | API

What is @ruvector/ruvllm?

@ruvector/ruvllm is a TypeScript/JavaScript SDK for intelligent LLM orchestration, specifically designed for Claude Code and multi-agent systems. It provides:

• RLM (Recursive Language Model) - Break complex queries into sub-queries, synthesize coherent answers
• 100% Routing Accuracy - Hybrid keyword + embedding strategy for perfect agent selection
• SONA Self-Learning - Model improves with every successful interaction
• SIMD Acceleration - AVX2/NEON optimized inference

Why @ruvector/ruvllm?

| Challenge | Traditional Approach | @ruvector/ruvllm Solution | |-----------|---------------------|---------------------------| | Agent selection | Manual or keyword-based | Semantic + keyword hybrid = 100% | | Complex queries | Single-shot RAG | Recursive decomposition + synthesis | | Response latency | 2-5 seconds | <1ms cache, 50-200ms full | | Learning | Static models | Self-improving (SONA) | | Cost per route | $0.01+ (API call) | $0 (local inference) |

Installation

npm install @ruvector/ruvllm

Quick Start

import { RuvLLM, RlmController } from '@ruvector/ruvllm';

// Simple LLM inference
const llm = new RuvLLM({
  modelPath: '~/.ruvllm/models/ruvltra-claude-code-0.5b-q4_k_m.gguf',
  sonaEnabled: true,
});

const response = await llm.query('Explain quantum computing');
console.log(response.text);

// Recursive Language Model for complex queries
const rlm = new RlmController({ maxDepth: 5 });
const answer = await rlm.query('What are the causes AND solutions for slow API responses?');
// Automatically decomposes into sub-queries, retrieves context, synthesizes answer

Core Features

1. Claude Code Native Routing

Built by Claude Code, for Claude Code. Routes tasks to 60+ agent types:

import { RuvLLM } from '@ruvector/ruvllm';

const llm = new RuvLLM({ model: 'ruv/ruvltra' });

// Intelligent routing
const route = await llm.route('implement OAuth2 authentication');
console.log(route.agent);      // 'security-architect'
console.log(route.confidence); // 0.98
console.log(route.tier);       // 2 (Haiku-level complexity)

// Multi-agent teams for complex tasks
const team = await llm.routeComplex('build full-stack app with auth');
// Returns: [system-architect, backend-dev, coder, security-architect, tester]

2. 3-Tier Intelligent Routing

3. Self-Learning (SONA)

Every successful interaction improves the model:

// First routing: Full inference
llm.route('implement OAuth2') → security-architect (97%)

// Later: Pattern hit in <25μs (learned from success)
llm.route('add OAuth2 flow') → security-architect (99%, cached pattern)

RLM (Recursive Language Model)

RLM provides recursive query decomposition - unlike traditional RAG that retrieves once, RLM breaks complex questions into sub-queries and synthesizes coherent answers.

How It Works

Query: "What are the causes AND solutions for slow API responses?"
                              ↓
                    [Decomposition]
                    /            \
    "Causes of slow API?"    "Solutions for slow API?"
           ↓                        ↓
    [Sub-answers]            [Sub-answers]
           \                        /
                    [Synthesis]
                         ↓
            Coherent combined answer with sources

Basic Usage

import { RlmController } from '@ruvector/ruvllm';

const rlm = new RlmController({
  maxDepth: 5,
  retrievalTopK: 10,
  enableCache: true,
});

// Add knowledge to memory
await rlm.addMemory('TypeScript adds static typing to JavaScript.');
await rlm.addMemory('React is a library for building user interfaces.');

// Query with recursive retrieval
const answer = await rlm.query('What are causes and solutions for type errors in React?');
console.log(answer.text);           // Comprehensive synthesized answer
console.log(answer.sources);        // Source attributions
console.log(answer.qualityScore);   // 0.0-1.0
console.log(answer.confidence);     // Routing confidence

Streaming

for await (const event of rlm.queryStream('Explain machine learning')) {
  if (event.type === 'token') {
    process.stdout.write(event.text);
  } else {
    console.log('\n\nQuality:', event.answer.qualityScore);
  }
}

With Self-Reflection

const rlm = new RlmController({
  enableReflection: true,
  maxReflectionIterations: 2,
  minQualityScore: 0.8,
});

// Answers are iteratively refined until quality >= 0.8
const answer = await rlm.query('Complex multi-part technical question...');

RLM Configuration

interface RlmConfig {
  maxDepth?: number;              // Max recursion depth (default: 3)
  maxSubQueries?: number;         // Max sub-queries per level (default: 5)
  tokenBudget?: number;           // Token budget (default: 4096)
  enableCache?: boolean;          // Enable caching (default: true)
  cacheTtl?: number;              // Cache TTL in ms (default: 300000)
  retrievalTopK?: number;         // Memory spans to retrieve (default: 10)
  minQualityScore?: number;       // Min quality threshold (default: 0.7)
  enableReflection?: boolean;     // Enable self-reflection (default: false)
  maxReflectionIterations?: number; // Max reflection loops (default: 2)
}

Unique Capabilities

1. Memory-Augmented Routing

Every successful routing is stored in HNSW-indexed memory for instant recall:

// First time: Full inference (~50ms)
route("implement OAuth2") → security-architect (97% confidence)

// Later: Memory hit (<25μs)
route("add OAuth2 flow") → security-architect (99% confidence, cached)

2. Confidence-Aware Escalation

// Low confidence automatically escalates
Confidence > 0.9  → Use recommended agent
Confidence 0.7-0.9 → Use with human confirmation
Confidence < 0.7  → Escalate to higher tier

3. Batch SIMD Operations

import { simd } from '@ruvector/ruvllm/simd';

// 4x faster vector operations with AVX2/NEON
const similarity = simd.batchCosineSimilarity(query, targets);
const attended = simd.flashAttention(q, k, v, scale);

4. Zero-Copy Caching

Arc-based string interning for 100-1000x faster cache hits on large responses.
