Extract Images

Boolean

extract_images

Whether to extract and embed images from documents.

Default true

Images Per Message

Integer

images_per_message

Number of images to batch per LLM request (higher = faster but may hit token limits).

Default 2

Pages Per Batch

Integer

pages_per_batch

Number of PDF pages to process in parallel (higher = faster but uses more memory).

Default 2

Temperature

Float

temperature

LLM temperature (0.0 = deterministic, 1.0 = creative). Lower is better for extraction.

Default 0.1

Max Tokens

Integer

max_tokens

Maximum output tokens per LLM call. Leave at 0 for model default. Set lower for unreliable models.

Default 4096

Prompt Preset

String

prompt_preset

Prompt contract of the selected model. Document-parsing models only answer to their own trained prompt: • Default — a tuned general prompt for vision models (GPT-4o, Claude, Gemini, Qwen-VL) • Unlimited-OCR — baidu/Unlimited-OCR, self-hosted via vLLM • DeepSeek-OCR — deepseek-ai/DeepSeek-OCR and -OCR-2 • olmOCR — allenai/olmOCR-2, emits YAML front matter • Nanonets-OCR — nanonets/Nanonets-OCR-s and -OCR2 • dots.ocr — plain text extraction; use Page Prompt for its JSON layout mode • Granite-Docling — IBM Granite-Docling and SmolDocling, emits DocTags • PaddleOCR-VL — PaddlePaddle/PaddleOCR-VL Every preset except Default forces full-page OCR and one image per request. Recommended temperature is 0.0 for all of them except olmOCR (0.1).

Page Prompt

String

page_prompt

Prompt for converting a rendered document page to text. Switching the preset rewrites this unless you have typed your own. Leave empty to fall back to the preset.

Image Prompt

String

image_prompt

Prompt for describing a standalone or embedded image. Switching the preset rewrites this unless you have typed your own. Leave empty to fall back to the preset.

Batch Image Prompt

String

batch_prompt

Prompt used when Images Per Message is greater than 1. Only the Default preset fills this in — the OCR presets never batch. Leave empty to fall back to the preset.

Force OCR

Boolean

force_ocr

Run every PDF page through the model instead of only pages whose extracted text looks poor. Presets other than Default turn this on regardless.

Default false
