Can LLMs Master Monopoly? New Test Puts Bots on the Board

Large language models (LLMs) have been making waves with their ability to tackle static financial reasoning. But when the stakes change and the board is set, how do these models handle real-world financial decisions? Enter FinBoardBench, a new evaluation suite aimed at testing LLMs on three classic financial board games: Cashflow, Acquire, and Monopoly.

The Game is On

FinBoardBench isn't just about Monopoly money. It's a test suite examining a variety of financial skills. Think personal cash flow management, corporate investment strategies, and the nuances of trade negotiations. The suite puts LLMs through their paces in areas that require a more dynamic approach to decision-making.

Nine advanced LLMs were put to the test, and the results were intriguing. While these models show basic long-term planning and investment logic, they often fall short in the fast-paced, unpredictable world of board games. Their tendency to prioritize immediate asset acquisition over maintaining liquidity leaves them exposed to financial pitfalls triggered by random events. If nobody would play it without the model, the model won't save it.

Why It Matters

Why should you care about AI playing board games? Because it highlights a fundamental gap in LLM capabilities. These models excel in static scenarios but struggle when the script isn't pre-written. The game comes first. The economy comes second. And in this case, the game is more complex than static benchmarks can measure.

Think about it. Would you trust an AI to manage your finances if it can't navigate a game of Monopoly without going bankrupt? Retention curves don't lie, and neither do board games. FinBoardBench provides a critical lens on how LLMs might perform in real-world financial environments, where decisions must be made on the fly and adapt to changing circumstances.

The Future of AI Financial Decision-Making

So, what's next for LLMs finance? FinBoardBench sets a new standard for evaluating these models, pushing them to improve their dynamic decision-making skills. It highlights the need for LLMs to not only think immediate gains but to also consider long-term financial stability.

Will future models learn from these lessons and better balance risk and reward in dynamic environments? Only time, and the next round of board game tests, will tell. This is the first AI game I'd actually recommend to my non-AI friends, if only for the laughs.

In the end, FinBoardBench offers more than just a test. It's a call to action for developers to hone LLMs that can handle both static and dynamic financial challenges. After all, the ability to adapt is what separates a good financial advisor from a great one.
