LangChain AI Scientist V2 leverages large language models and LangChain’s agent framework to assist researchers at every stage of the scientific process. It ingests academic papers for literature reviews, generates novel hypotheses, outlines experimental protocols, drafts lab reports, and produces code for data analysis. Users interact via CLI or notebook, customizing tasks through prompt templates and configuration settings. By orchestrating multi-step reasoning chains, it accelerates discovery, reduces manual workload, and ensures reproducible research outputs.

Virtual Scientists V2 serves as a modular AI agent framework tailored for scientific research. It defines multiple virtual scientists—Chemist, Physicist, Biologist, and Data Scientist—each equipped with domain-specific knowledge and tool integrations. These agents utilize LangChain to orchestrate API calls to sources like Semantic Scholar, ArXiv, and web search, enabling automated literature retrieval, contextual analysis, and data extraction. Users script tasks by specifying research objectives; agents autonomously gather papers, summarize methodologies and results, propose experimental protocols, generate hypotheses, and produce structured reports. The framework supports plugins for custom tools and workflows, promoting extensibility. By automating repetitive research tasks, Virtual Scientists V2 accelerates insight generation and reduces manual effort across multidisciplinary projects.
