# Doc-Split Demo

Upload a PDF that concatenates several documents; the model marks where each new document begins and groups
the pages into documents. Pick **doc-split-v2** (commercial flagship) or the open **doc-split-v1**. Uses the PDF's embedded
text layer where present; scanned pages fall back to the image model. Confidence is calibrated.

## Secret required

**doc-split-v2** is commercial and loaded from a **private** repo, so this Space needs an `HF_TOKEN`
**secret** (Settings → Variables and secrets) with read access to it. The weights are used server-side only
and are never downloadable. Without the secret, the v2 model is marked _unavailable_ and the open **doc-split-v1**
still runs. Inference runs on **ZeroGPU**.
