What each one is
AI Berkshire
AI Berkshire is a collection of investment research "skills" (structured prompts and workflows) that run inside Claude Code or Codex. It is built around the investing methods of Buffett, Munger, Duan Yongping and Li Lu, and includes multi-agent workflows where several agents research a company in parallel and then a lead agent combines their conclusions. The README is largely in Chinese and focuses on Chinese and US stocks.
Vibe-Trading
Vibe-Trading is a Python project that lets you use an AI agent for trading-related work, such as research and backtesting. The README describes it as a personal trading agent that you install with a single pip command and then connect to your own tools. Its topics include backtesting, multi-agent systems, quantitative finance and MCP, and the README mentions paper trading and portfolio connections to brokers like IBKR and Futu.

Not ideal for
AI Berkshire
- Anyone wanting guaranteed or verified investment returns: the README's performance figures are self-reported and it warns that past returns do not predict future ones
- Beginners without an AI coding client subscription, since the skills depend on Claude Code or Codex
- People who need a licensed financial advisor's personal recommendation; the project is a research aid, not advice
Vibe-Trading
- People looking for a ready-made system that makes profitable trades; the README does not claim performance and this is research software
- Anyone who needs a polished no-code app, since the README centers on a command-line install and Python setup
- Users who want to connect a wallet or buy tokens; the README warns that related token and memecoin claims are not official
Trade-offs
AI Berkshire
- Output quality depends on the underlying model and on data sources the README does not fully describe; the README itself notes higher-stakes analysis benefits from stronger models
- The track-record claims are shown as screenshots and a table, and cannot be independently verified from the repository alone
- Documentation is mainly in Chinese, with the main market focus on Chinese and US equities
Vibe-Trading
- The README is truncated and does not fully explain every feature, so details may be incomplete
- Many recent changes are marked unreleased and listed as fixes, so behavior may shift between versions
- Trading software carries financial risk, and the README does not provide investment guidance
