The main updates include: + + - OCR model upgrade and processing acceleration + - The OCR model for the `pipeline` backend has been upgraded to `PP-OCRv6`, improving OCR accuracy by about `11%` on OmniDocBench v1.6. + - Removed Japanese, Traditional Chinese, English, and Latin options from OCR language selection. These scenarios are now routed to the `ch` OCR model, simplifying model configuration and language selection. + - Optimized the OCR inference and processing pipeline, increasing OCR processing speed by about `100%` and significantly improving parsing efficiency for batch documents and OCR-intensive documents. + + - Model download logic optimization + - Added automatic model source selection, allowing first-time installations to choose a better model source based on the current network environment. + - Before downloading models, MinerU now prioritizes checking locally downloaded model cache files. Cache hits can be reused directly, reducing repeated downloads and unnecessary remote requests. + - For more details about model source configuration, automatic source selection, and local model usage, see the [Model Source Documentation](https://opendatalab.github.io/MinerU/en/usage/model_source/). + + With the 3.4 release, MinerU further improves the parsing accuracy and processing efficiency of the `pipeline` backend in OCR scenarios. It also optimizes model downloads, cache reuse, and local configuration write-back, making first-time installation, model updates, and multi-environment deployment more stable and automated. + - 2026/06/11 3.3 Released This release focuses on **Hybrid parsing performance optimization** and **VLM model capability upgrades**.
