-Gemmascope is TODO
+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.
 
-# 2. What Is `gemmascope-9b-pt-att`?
+See our [landing page](https://huggingface.co/google/gemma-scope) for details on the whole suite. This is a specific set of SAEs:
 
-- `gemmascope-`: See 1.
-- `9b-pt-`: These SAEs were trained on the Gemma v2 9B base model (TODO link).
-- `att`: These SAEs were trained on the attention layer outputs, before the final linear projection (TODO link ckkissane post).

-## 3. GTM FAQ (TODO(conmy): delete for main rollout)
+- `gemma-scope-`: See 1.
+- `9b-pt-`: These SAEs were trained on Gemma v2 27B base model.
+- `att`: These SAEs were trained on the model's attention layer output before the linear projection.
 
-Q1: Why does this model exist in `gg-hf`?
-
-A1: See https://docs.google.com/document/d/1bKaOw2mJPJDYhgFQGGVOyBB3M4Bm_Q3PMrfQeqeYi0M (Google internal only).
-
-Q2: What does "SAE" mean?
-
-A2: Sparse Autoencoder. See https://docs.google.com/document/d/1roMgCPMPEQgaNbCu15CGo966xRLToulCBQUVKVGvcfM (should be available to trusted HuggingFace collaborators, and Google too).
-
-TODO(conmy): remove this when making the main repo.
