Open-source tool optimizes AI models for lower cost and higher efficiency

Experiential Labs has released an open-source tool called World Model Optimizer (wmo) designed to reduce the cost of serving AI models. The tool optimizes agent traces to create smaller, more efficient models, and can route requests between frontier and smaller models to maintain quality at a lower cost. It supports various optimization strategies, including distilling models, serving single models, and building optimized harnesses for agents, with options for local or cloud-hosted execution. AI

IMPACT Enables developers to reduce AI inference costs and improve model efficiency.
