Deeply explain, critique, reproduce, or situate an academic paper for a reader entering an unfamiliar field. Use for 读论文, 论文精读, 帮我吃透这篇论文, paper deep dive, method/figure/experiment analysis, author or lab context, related work and GitHub discovery, technical history, reviewer mode, implementation mode, and research opportunities. Turn the paper into a compact, plain-language mental model first; use inspected paper figures and selective generated teaching visuals when they improve understanding; then place exact evidence and technical detail in an optional appendix. Distinguish fact from inference internally and never let audit machinery overwhelm the teaching story.
