# ProSST structure tokenizer (rem2 / VenusREM2)
Structure-token assets used by [`rem2`](https://github.com/tyang816/VenusREM2) when you run `--model prosst` or `--model venusrem2`.
On first use, rem2 downloads only the files it needs into `~/.cache/rem2/weights/prosst/static/`:
| File | Used by |
|------|---------|
| `static/AE.pt` | All ProSST vocab sizes |
| `static/{K}.joblib` | `--model prosst-{K}` and VenusREM2 members. K ∈ {20, 64, 128, 512, 1024, 2048, 4096} |
VenusREM2's official ensemble uses K ∈ {20, 128, 512, 1024, 2048, 4096} (not 64).
These files are the **local structure tokenizer** (`AE.pt` + k-means vocab). They are not the ProSST language-model weights.
