# 2. What Is `gemmascope-9b-pt-mlp`?

- `gemmascope-`: see 1.
- `9b-pt-`: These SAEs were trained on the Gemma v2 9B base model (TODO link)
- `mlp`: These SAEs were trained on the outputs of MLP layers.

## 3. GTM FAQ (TODO(conmy): delete for main rollout)

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.
