LMaaS: Exploring Pricing Strategy of Large Model as a Service for Communication

no code implementations5 Jan 2024 Panlong Wu, Qi Liu, Yanjie Dong, Fangxin Wang

In the first step, we optimize the seller's pricing decision and propose an Iterative Model Pricing (IMP) algorithm that optimizes the prices of large models iteratively by reasoning customers' future rental decisions, which is able to achieve a near-optimal pricing solution.
