Developer @ActbroDev releases MiniCPM5-2B-Jev, a System 1 decision model built on OpenBMB's MiniCPM5-2B. Instead of free-form text, the model returns probabilities for predefined options.

The project reports 78.79% on JevBench, which it says ranks first among open-weight System 1 / Jev models at 2B parameters or fewer, and 86.41% accuracy on the 10-source decision-v7 benchmark. These figures are the developer's own reported results.

The code, LoRA adapters, and a calibration head are released under Apache 2.0.
