# GPT-2 Decomposed — Model Garage
|
| 13 |
+
|
| 14 |
+
Full component-level decomposition of GPT-2 (124M parameters) using [Model Garage](https://github.com/Lumi-node/model-garage).
|

+
## What's Here
|
| 17 |
+
|
| 18 |
+
64 individually extracted `nn.Module` components:
|
| 19 |
+
|
| 20 |
+
| Component Type | Count | Dimensions |
|
| 21 |
+
|---------------|-------|-----------|
|
| 22 |
+
| Attention (self_attn) | 12 | 768d, 12 heads, 64 head_dim |
|
| 23 |
+
| Feed-Forward (mlp) | 12 | 768→3072→768 |
|
| 24 |
+
| Layer Norm (ln_1, ln_2) | 24 | 768d |
|
| 25 |
+
| Full Layers | 12 | 768d |
|
| 26 |
+
| Embeddings | 2 | token (50257→768), position (1024→768) |
|

## Usage
|
| 31 |
+
|
| 32 |
+
```python
|
| 33 |
+
from model_garage.extract.pytorch import PyTorchExtractor
|
| 34 |
+
|
| 35 |
+
extractor = PyTorchExtractor("gpt2")
|
| 36 |
+
extractor.load_model()
|
| 37 |
+
|
| 38 |
+
# Extract any component
|
| 39 |
+
attn = extractor.extract_component("self_attention", layer_idx=6)
|
| 40 |
+
ffn = extractor.extract_component("feed_forward", layer_idx=6)
|
| 41 |
+
|
| 42 |
+
# Test in isolation
|
| 43 |
+
from model_garage.extract.pytorch import ComponentTester
|
| 44 |
+
tester = ComponentTester()
|
| 45 |
+
print(tester.test_attention(attn))
|
| 46 |
+
```
|
| 47 |
+
|
