Organ Architecture provides tools to analyze, modify, and recombine AI model components. Visualize attention heads, extract MLP layers, transplant capabilities between models — all locally.

## What You Can Do

- **Visualize** — Inspect layer activations, attention patterns, embedding geometry
- **Extract** — Pull specific layers, heads, or modules from any GGUF model
- **Transplant** — Merge capabilities from multiple models
- **Prune** — Remove redundant layers to create smaller, faster models
- **Quantize** — Convert between precisions (F32 → F16 → Q8 → Q4 → Q2)

## Supported Model Families (Feb 2026)

Llama 3.x · Qwen 2.5 · DeepSeek R1 · Mistral · Gemma 2 · Phi-4 · Command-R

## Quick Start

```bash
git clone https://git.inference-x.com/inference-x/organ-architecture
cd organ-architecture && make

# Analyze a model
./organ analyze model.gguf

# Visualize attention patterns
./organ visualize model.gguf --layer 16 --head 0

# Extract layers 0-20
./organ extract model.gguf --layers 0-20 --output model_small.gguf

# Merge two models (50/50)
./organ merge base.gguf specialist.gguf --ratio 0.5 --output merged.gguf

# Quantize F16 → Q4_K_M
./organ quantize model.f16.gguf --target Q4_K_M
```
