Factory COO @francesca_lab says the enterprise AI stack is becoming less about picking one best model and more about routing every task to the right one: "We're definitely seeing a model mix. Cost is a big part of the equation. We really want to maximize ROI for our customers, not just maximize token spend." "Open source is picking up a pretty big share. Certain models are good at different use cases. Maybe you're using a different model for code review than you're using for your migration project." "We optimize the right model per task based on that cost/performance trade-off." "The router needs to be tied to the harness, because you need to have the output right next to the router in that decision, versus just routing to the model that is the cheapest." @FactoryAI
