Model overview
Fine-tuned image classifiers that sort scanned archive pages into eleven content categories, so that each page can be sent to the processing it needs: OCR for printed or typed text, handwriting recognition for manuscripts, table extraction for forms, image extraction for drawings and photographs. They look at the page image only, so the language of the page does not matter. The code, the command line and the HTTP service are in atrium-page-classification [^3]. Every version is a **revision** (branch) of this repository [^1]. They share the eleven categories and differ in their training data and base model: ViT [^2] [^6] [^7], EfficientNetV2 [^8] [^9] [^11] or RegNetY [^12]. The current generation is **`vX.4`**: five base models, retrained on the licence-compatible public dataset [^10]. **Name the revision when you load a model:** `main` still holds `v4.3`, the generation before. Each model was scored on the test partition of its own fold of the dataset (folds 1, 1, 2, 2 and 5; 4,791–4,795 pages each), on 22 October 2026. The five together, averaged, are the code's ensemble (`--best`, and the default of its HTTP service).

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
