RuvLLM

Self-Optimizing Neural Architecture (SONA) with TRM Recursive Reasoning, LFM2 Cortex, Ruvector Memory, and Intelligent Routing

"The intelligence is not in one model anymore. It is in the loop."

What is RuvLLM?

RuvLLM is a self-learning language model orchestration system that combines frozen foundation models with adaptive memory and intelligent routing. Unlike traditional LLMs that rely solely on static parameters, RuvLLM continuously improves from every interaction through three temporal learning loops.

Key Innovation: RuvLLM doesn't replace your LLM—it makes any LLM smarter over time by learning from experience, routing intelligently, and preventing catastrophic forgetting.

EWC++ (Enhanced Elastic Weight Consolidation)

Prevents catastrophic forgetting:

Loss = Task_Loss + λ * Σᵢ Fᵢ(θᵢ - θ*ᵢ)²

Where:
• Fᵢ = Online Fisher information (EMA decay 0.999)
• θ*ᵢ = Optimal weights for previous tasks
• λ = Adaptive (2000 default, range 100-15000)
• Multi-task memory with circular buffer (10 tasks)
• Automatic task boundary detection

SIMD Operations

Native CPU acceleration:

// AVX2 dot product (8 floats at a time)
#[target_feature(enable = "avx2")]
unsafe fn dot_product_avx2(a: &[f32], b: &[f32]) -> f32

// SSE4.1 fallback (4 floats at a time)
#[target_feature(enable = "sse4.1")]
unsafe fn dot_product_sse(a: &[f32], b: &[f32]) -> f32

// Automatic detection and dispatch
let result = SimdOps::dot_product(&a, &b);
