chandra-OCR-GGUF
Chandra is a highly accurate OCR model designed to convert images and PDFs into structured outputs such as markdown, HTML, and JSON while preserving detailed layout information. It supports over 40 languages and excels in handling complex document elements including handwriting, tables, math expressions, forms with checkboxes, and diagrams with captions. Chandra offers flexible inference modes with local execution via HuggingFace or remote deployment using a vLLM server, making it suitable for both interactive use and large-scale batch processing. Its strong layout preservation and multilingual capabilities make it a versatile choice for document digitization and automated content extraction workflows.
