   - 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.

 - `HuggingFace` provides excellent loading speed and high stability globally.
 - `ModelScope` is the best choice for users in mainland China, providing seamlessly compatible `hf` SDK modules, suitable for users who cannot access HuggingFace.
