# Callosum Raises $100 Million to Match AI Tasks with Most Cost-Effective Models

> Callosum has raised 100 million dollars to build software that matches each AI task to the most cost-effective model and chip to run it, rather than sending everything to a single expensive frontier model. The pitch targets a real and growing pain point: enterprises routinely overpay by routing routine, high-volume work to premium models that are overkill for the job. As the model landscape fragments into dozens of options at wildly different price and quality points, deciding what runs where has become its own engineering problem. Callosum is betting that this routing layer, sometimes called a model router, becomes essential infrastructure, quietly steering commodity workloads to cheap models while reserving the expensive ones for the hard cases. The raise, reported by Bloomberg, is a sign that investors see the money in optimization rather than in building yet another model. As the industry worries about the cost of running AI at scale, tools that shave the bill without hurting quality look increasingly valuable.
