MinerU 4.0
MinerU 4.0 brings document parsing, a local document library, and service tools into one workflow for document conversion, application integration, and agent reading.
- Four parsing tiers: Flash for fast previews and indexing, Basic for OCR and model-based parsing, and Standard / Advanced for more demanding layouts and quality requirements.
- Multiple input formats: PDF, images, DOC/DOCX, PPT/PPTX, XLS/XLSX, RTF, ODT/ODS/ODP, EPUB, OFD, HTML, and CSV/TSV. DocVortex provides native document parsing.
- Document library and agent reading: discover files, cache results, search content, continue by page or block, and preserve stable citation locators.
- Independent model configuration: ONNX or Torch for small models; llama.cpp, vLLM, or LMDeploy for the VLM.
- Unified tools: Python SDK, V1 API, stateless batch conversion, multi-service Router, and a Gradio-based WebUI.
- Structured results and rendering: one document model supports nine rendering targets: Markdown, HTML, LaTeX, DOCX, EPUB, PDF, Structured Content, and Content List V1/V2. Each CLI/API exposes its own subset of exports; see Output Formats and Result Contract.
PDF and images support all four tiers. Office, OpenDocument, EPUB, OFD, HTML, and CSV/TSV use local Flash native parsing. Plain text is read directly rather than parsed. Documents are not automatically uploaded to the official service; remote parsing requires explicit configuration.
