# OCR

> Vision-language reading of page regions

The **OCR** model is a vision-language reader. It takes the crops produced by [layout](/products/models-layout) and turns each region into machine-readable text. Convert on the [Middleware API](/products/middleware) uses it for scans, photographed pages, and native PDFs that still need structure recovered.

## Configuration

| Setting  | How it is configured                                                                     |
| -------- | ---------------------------------------------------------------------------------------- |
| Routing  | Each crop is sent to a task chosen from its layout type, not to one generic prompt.      |
| Text     | Body copy, titles, headings, headers, footers, and footnotes use a general reading task. |
| Tables   | A dedicated table pass. Output is structured tables, not a flattened paragraph.          |
| Formulas | A dedicated formula pass. Output is mathematical notation.                               |
| Charts   | A dedicated chart pass. Output is the chart's structure and values.                      |
| Seals    | A dedicated seal pass for stamps and chops.                                              |
| Figures  | Images use a separate vision-language description pass.                                  |
| Serving  | AiQL selects the checkpoint and timeouts. Customers do not pick an OCR model.            |
