Could you build this?
No This is a from-scratch reproduction of a decision model, trained on a Qwen base with fine-tuning and probability calibration. It requires ML research and training compute, and the model design is novel rather than wrapping an existing API.
What it would actually take: Building it requires a training pipeline on a Qwen-family base, custom data for the Choice and Noul language formats, and reasoning and calibration work such as ECE-based calibration. That needs ML engineers who can run fine-tuning on GPUs and evaluate results rigorously. The original System One design also has to be understood well enough to reproduce.
