Four open models tested on one design task, MiniMax M3 leads on cost

A head-to-head test running the same design-generation prompt across four open-weight models, MiniMax M3, GLM-5.2, DeepSeek V4 Pro and Kimi K2.7 Code, has drawn attention after MiniMax M3 matched GLM-5.2 on quality at a far lower cost. The test used a coding tool's design-generation feature, giving each model the same task and comparing output quality against API cost directly.
