Could you build this?
Partial Setting up Modal pipelines and serving open models is straightforward, but fine-tuning Gemma models to achieve calibrated single-pass decision-making requires specialized statistical calibration data and training scripts.
What it would actually take: A full reproduction requires setting up Modal serverless GPU infrastructure hosting fine-tuned Gemma checkpoints (270M and 2B parameters). The challenging part is the calibrated probability estimation and constrained decoding mechanism (replicating TypeSafe's Jev framework) which relies on conformal prediction, Platt scaling, or specific logit calibration techniques over domain-specific structured outputs. It requires machine learning expertise in calibrated uncertainty estimation and structured LLM outputs.
