However, open-source extractors often fail on documents that are not academic papers, such as textbooks, exam sheets, reports and slides. End-to-end MLLM parsers are expensive to run and still struggle with varied inputs.

The authors address both problems with the Art of Problem… ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[Structural basis of CXC chemokine receptor 2 activation and signalling ↗](https://doi.org/10.1038/s41586-020-2492-5) Nature · no summary yet**Kaiwen Liu et al.*2020 · 221 citations* 2.
