# OCR Model Workbench — Gateway

This Space provides the shared Gradio UI. It does not load OCR weights itself; it sends page images to model-specific worker Spaces.

Set these Space Variables:

- `PADDLEOCR_VL_WORKER_URL`
- `QIANFAN_WORKER_URL`
- `UNLIMITED_WORKER_URL`
- `PPOCRV6_WORKER_URL`

Optional secrets:

- `HF_TOKEN`: needed when worker Spaces are private.
- `WORKER_API_TOKEN`: shared token checked by workers through `X-OCR-Worker-Token`.

Optional limits:

- `MAX_INPUT_MB=80`
- `DEFAULT_MAX_PAGES=8`
- `ABSOLUTE_MAX_PAGES=40`
- `STALE_RUN_HOURS=12`（一時結果の保持時間）
