hi_res_model_name
-----------------
- **Type**: string
- **Description**: The name of the inference model used when strategy is hi_res.
- **Example**: yolox

- **Type**: boolean
- **Description**: If True, the output will include page breaks if the filetype supports it. Default: false.

languages
---------
- **Type**: array

- **Default**: []
- **Example**: [eng]

pdf_infer_table_structure
-------------------------
- **Type**: boolean
- **Description**: Deprecated! Use skip_infer_table_types to opt out of table extraction for any file type. If False and strategy=hi_res, no Table Elements will be extracted from pdf files regardless of skip_infer_table_types contents.

skip_infer_table_types

- **Type**: array
- **Description**: The document types that you want to skip table extraction with. Default: ['pdf', 'jpg', 'png', 'heic'].

xml_keep_tags

- **Description**: Use one of the supported strategies to chunk the returned elements. Currently supports: by_title.
- **Example**: by_title

multipage_sections
------------------
- **Type**: boolean

combine_under_n_chars
---------------------
- **Type**: integer

- **Example**: 500

new_after_n_chars
-----------------

- **Example**: 1500

max_characters
--------------
- **Type**: integer
- **Description**: If chunking strategy is set, cut off new sections after reaching a length of n chars (hard max). Default: 1500.
- **Example**: 1500

extract_image_block_types
-------------------------
- **Type**: array
- **Description**: The types of image blocks to extract from the document. Supports various Element types.
- **Example**: ['Image', 'Table']
