Docling GLM-OCR Plugin

A Docling OCR plugin that delegates text recognition to a remote GLM-OCR model served via vLLM.

GitHub Repository: DCC-BS/docling-glm-ocr

Features

• Remote Delegation: Offloads OCR processing to a remote vLLM server hosting zai-org/GLM-OCR.
• Markdown Output: The model returns Markdown-formatted text, preserving headings, tables, and formulas.
• Concurrent Processing: Sends page crops as base64-encoded images via concurrent API requests with retry logic.
• Engine Key: Registers under the "glm-ocr-remote" engine key.

Installation

• Using uv (recommended): uv add docling-glm-ocr
• Using pip: pip install docling-glm-ocr
