RPC-Bench is a fine-grained benchmark for research paper comprehension. It is built from review-rebuttal exchanges of high-quality academic papers and supports both text-only and visual evaluation through complementary paper representations.

## Data Structure

RPC-Bench is split into `train`, `dev`, and `test` subsets. Each subset is stored in the dataset structure and recorded in `manifest.jsonl`.

`md/` contains Markdown files parsed from each paper by MinerU. These files provide the text input for LLM-oriented evaluation.

`parse/` contains the full MinerU parsing outputs for each paper, including structured layout and content artifacts.

`pdf/` contains the original paper PDFs.

`vlm/` contains page images rendered from the PDFs with PyMuPDF at 200 DPI for VLM-oriented evaluation.

## Practical Uses

RPC-Bench can be used to try paper-centric systems that require broader document understanding rather than local snippet matching.

- Research paper comprehension: try models on full-paper understanding, including core concepts, methods, and experimental findings.
- Long-context evaluation: try whether longer context windows or long-context architectures improve document-level reasoning.
- Multimodal reasoning: try models that combine textual evidence with page-level figures, tables, and diagrams in the original PDF layout.
- RAG system diagnosis: try retrieval, chunking, and evidence-fusion strategies for paper-centric workflows beyond snippet-level retrieval accuracy.
