In the evolving landscape of AI, understanding complex models can often seem daunting. However, with the right tools, such as Gemma Scope, diving deep into a model’s workings becomes a more manageable task. This blog walks you through the essentials of using the Gemma Scope suite of sparse autoencoders (SAEs) to demystify model activations and interpretations.
Understanding Gemma Scope
Gemma Scope is an open suite designed specifically for analyzing models like the 9B and 2B versions of the Gemma framework. Think of sparse autoencoders as a “microscope”—they allow you to zoom in on the intricate details of a model’s activations, revealing the underlying concepts just like biologists study individual cells through a microscope. Whether you’re a seasoned pro or a curious newbie, Gemma Scope offers a comprehensive toolkit for your needs.
What Is `gemma-scope-2b-pt-res`?
- gemma-scope-: Refers to the Gemma Scope suite as introduced above.
- 2b-pt-: This indicates that the corresponding SAEs were specifically trained on the Gemma v2 2B base model.
- res: These SAEs focus on the model’s residual stream, providing deeper insights into specific data flows.

Troubleshooting Tips
As with all complex tools, you may encounter issues while working with Gemma Scope. Here are a few troubleshooting ideas:
- Labeling Issues: If you find some SAEs appearing twice, don’t worry! This is a known issue and does not affect the overall functionality.
- Connection Problems: If you’re having trouble reaching the demo sites or tools, ensure that your internet connection is stable and that there are no firewalls blocking access.
- Performance Issues: Should the system lag or crash, try refreshing your browser or clearing the cache to improve performance.
