Could you build this?

No WattAI is a custom distilled, quantized small language model (distilled from SmolLM2-360M) optimized specifically for zero-shot calibrated probability classification on edge devices.

What it would actually take: Building this requires a dedicated machine learning pipeline to perform knowledge distillation from larger LLMs into a 360M parameter architecture using specialized evaluation datasets (MNLI, BoolQ, CLINC150). The model needs specialized probability calibration techniques (minimizing Expected Calibration Error) and compilation down to runtime formats like GGUF/ONNX for cross-platform, on-device CPU/NPU execution.
