# Recognition modes

Use the `-mode` parameter to choose between higher-fidelity output and faster results.

## Setting the mode

Pass the `-mode` parameter when you start the container. The mode determines how much of the document FineParser extracts, and how long each page takes.

```bash theme={null}
docker run -p 8080:8080 fineparser -mode fast
```

| Mode                    | Flag       | Results                                                                                                                         |
| ----------------------- | ---------- | ------------------------------------------------------------------------------------------------------------------------------- |
| High fidelity (default) | `accurate` | Reads the text and reconstructs the document's structure: layout, tables, checkboxes, and reading order. Takes longer per page. |
| Fast                    | `fast`     | Reads the text only. Skips structure analysis, so pages finish much faster.                                                     |

## Fixed per container

The mode is loaded at startup and cannot be changed at runtime. To serve both modes, run two containers. See [Configuration](/fine-parser/basics/configuration).
