Could you build this?
No Developing a novel 150M-parameter typed decision engine capable of single-pass non-autoregressive inference and calibrated confidence requires deep ML research expertise.
What it would actually take: Building this requires designing a custom transformer or encoder architecture in PyTorch, developing multi-task training objectives (combining classification, regression, and temperature-scaled uncertainty calibration), and curating representative decision datasets. It requires advanced expertise in statistical learning, uncertainty quantification, and efficient neural network training.
