MinerU 4: give your AI PDF answers a page and block you can check

I use this guide to read page and block locators, verify an extracted citation, and check parsing and license conditions. MinerU4 integrates parsing tiers, a local document library, cached results, search, page/block continuation and stable citation locators. It distinguishes native office parsing from PDF/image quality tiers and explicit remote parsing.

The source documentation was inspected; I have not independently run the proposed test in this guide. These steps help you choose and check a small first experiment before committing a larger workflow. Any successful output needs its own saved result and configuration.
