Cost-Optimal Foundation Model Deployment Portfolio for Transportation Management

Jul 16, 2026

Researchers introduce the Foundation Model Deployment Portfolio (FMDP) problem, formulating it as a mixed-integer program to minimize the total cost of ownership for deploying large language and vision-language models across transportation management center (TMC) tasks. Their case study demonstrates that a mixed deployment strategy—using open-source APIs for most functions and a closed API only where necessary—can reduce costs by 97% compared to the cheapest all-closed-API baseline, achieving a monthly cost of $34. The study also analyzes when on-premise GPU investment becomes cost-effective.

Why it matters: This work offers a formal, practical framework for optimizing the deployment of foundation models in cost-sensitive, multi-function environments like transportation management centers.
