Ai Berkshire
AI Berkshire is an open-source value investing research framework designed to work with AI assistants like Claude Code and Codex. It implements the methodologies of four renowned investors—Warren Buffett, Charlie Munger, Duan Yongping, and Li Lu—by orchestrating multiple AI agents to perform parallel research on potential investments. The framework provides structured prompts and workflows that guide the AI through fundamental analysis tasks such as evaluating moats, management quality, financial health, and intrinsic value. By leveraging multi-agent parallelism, AI Berkshire aims to accelerate the due diligence process for value investors, allowing simultaneous deep dives into multiple companies. Users can customize the agent roles and research criteria based on the philosophies of each master investor, enabling comparative analysis and generating investment theses. The tool is intended to augment, not replace, human decision-making by providing AI-generated insights grounded in time-tested value investing principles. The project is primarily developed in Chinese and targets users familiar with Chinese stock markets, though the underlying concepts are universal. It expects access to Claude Code or Codex, making it a niche tool for developers and researchers comfortable with AI-oriented coding environments. As an open-source initiative, it invites community contributions to expand its agent capabilities, integrate additional data sources, and refine the research templates.
