# 1. Gemma Scope |
|
|
|
Gemma Scope is a comprehensive, open suite of sparse autoencoders for Gemma 2 9B and 2B. Sparse Autoencoders are a "microscope" of sorts that can help us break down a model’s internal activations into the underlying concepts, just as biologists use microscopes to study the individual cells of plants and animals. |

|
See our [landing page](https://huggingface.co./google/gemma-scope) for details on the whole suite. This is a specific set of SAEs: |
|
|
|
# 2. What Is `gemma-scope-2b-pt-att`? |
|
|
|
- `gemma-scope-`: See 1. |
|
- `2b-pt-`: These SAEs were trained on Gemma v2 2B base model. |
|
- `att`: These SAEs were trained on the attention layer outputs, before the final linear projection. |
|
|
|
# 3. How can I use these SAEs straight away? |
|
|
|
```python |
|
from sae_lens import SAE # pip install sae-lens |
|
|
|
sae, cfg_dict, sparsity = SAE.from_pretrained( |
|
release = "gemma-scope-2b-pt-att-canonical", |
|
sae_id = "layer_0/width_16k/canonical", |
|
) |
|
``` |
|
|
|
See https://github.com/jbloomAus/SAELens for details on this library. |
