Could you build this?
No Distilling and training a calibrated probability model on top of Qwen3.5-4B that ranks near top benchmarks requires proprietary benchmark evaluation, extensive compute resources, and deep machine learning expertise in model distillation and calibration.
What it would actually take: Developing this requires a custom LLM fine-tuning and distillation pipeline using PyTorch, DeepSpeed/vLLM, and LoRA adapters. The core difficulty lies in generating high-quality synthetic calibration datasets, structuring loss functions to force calibrated output probabilities rather than typical overconfident logits, and conducting extensive empirical evaluation across benchmark suites.
