The Gear Head Philosophy

"People used to be 'Gear Heads' — they could fine-tune actual car engines manually. They understood every part, could diagnose problems by sound, and could build a hot rod from junkyard parts.

Modern AI models are the same kind of machine. They have parts — attention heads, feed-forward networks, embeddings, normalization layers. These parts can be extracted, tested in isolation, swapped between models, and recombined into something new.

Model Garage makes you a neural network gear head."

The Garage Metaphor

Every tool in Model Garage maps to a mechanic's toolkit:

Garage Tool Mechanic's Equivalent What It Does
Core (loader, hooks, tensor) Central air compressor Powers everything else
Extractors Wrenches & socket sets Pull components out of models
Injectors Pneumatic tools Install new parts mid-layer
Analyzers Diagnostic scanner (OBD-II) Read what each component is doing
Composers Engine build bench Assemble hybrids from extracted parts
Registry Parts catalog Track what you have and where it came from
Snapshots High-speed camera Capture hidden states in motion

Why This Matters

Neural networks are often treated as black boxes. Model Garage treats them as machines with accessible, modifiable parts:

  1. Demystification — See exactly what each layer contributes
  2. Experimentation — Swap parts between models to test hypotheses
  3. Capability transfer — Move learned abilities from one model to another
  4. Hybrid architectures — Build new models from proven components
  5. Alignment research — Understand and control model behavior at the component level

The Four Layers of Value

Layer 4: Pipeline Systems
         Complete workflows for specific applications

Layer 3: Methodologies
         Validated processes (blade injection, capability transfer)

Layer 2: Combinations
         Research insights from mixing and analyzing components

Layer 1: Platform
         The toolkit itself — extract, inject, analyze, compose

Model Garage starts at Layer 1 and grows upward as the community discovers new combinations and methodologies.
