Multi-Model Finance Game Uses Diverse AI Agents

Thousand Token Wood's second version transforms a simple simulation into an interactive finance game, where players act as shadow financiers in a woodland economy. The game now employs four distinct small models from different labs, each representing a unique creature with its own economic behavior. This diversity in models creates a dynamic and unpredictable market environment, enhancing the game's complexity and realism. The engineering challenge was primarily in the serving layer, not the modeling, highlighting the importance of infrastructure in multi-model systems. This approach demonstrates how small models can be leveraged for complex simulations without requiring massive computational resources.
