-Use [Mistral's OCR API](https://mistral.ai/) to extract text and page structure from a PDF uploaded to Sim or supplied by URL. The current parser returns page Markdown, image metadata, the model, and usage information. **Specific Pages** accepts zero-based indices such as `0,1,2`; leave it empty to process all pages. The block offers Markdown, plain-text, and JSON format values, but its current result uses the structured page output documented below. Turn on **Extract Images** to get the images Mistral finds in the document (figures, logos, photos) as files on the `images` output, up to 100 per parse; each page's image entry carries a `file_name` matching its file. **Max Images** and **Min Image Size** (advanced) narrow what is extracted. **Tables** keeps tables inline in the page Markdown by default, or returns them separately as Markdown or HTML in each page's `tables` list.
