Frequently Asked Questions

Is Kimi K2 good for academic research?
Kimi K2 is useful for reading long papers (128K context) and reasoning through arguments. But it lacks a paper database, citation verification, library management, and systematic review capabilities. It's a general AI, not a research tool.
Can Kimi K2 search academic papers?
Kimi K2 can search the web, which may surface some academic content. It cannot search Semantic Scholar (200M+ papers) or OpenAlex (250M+ works) directly, and it cannot verify that papers actually exist in scholarly catalogs.
Should I use Kimi K2 or PapersFlow?
Use both. Kimi K2 excels at reading individual papers and reasoning. PapersFlow excels at finding papers, managing your library, writing with verified citations, and creating presentations. They complement each other.
Does Kimi K2 hallucinate citations?
Yes — like all general AI models, Kimi K2 generates citations from training data patterns. These may look correct but reference non-existent papers. PapersFlow's Chain of Verification prevents this by checking every citation against scholarly databases.
Can Kimi K2 do a literature review?
Kimi K2 can help summarize papers you paste into the chat, but it cannot search academic databases, follow citation chains, screen hundreds of papers, or produce a verified synthesis. PapersFlow's Deep Research handles the full literature review pipeline.
