One-pass typed decisions with calibrated probabilities (System One style model), fine-tuned from Qwen3.5-2B

A family of System One-style models fine-tuned from Qwen3.5, designed for one-pass typed decisions with calibrated probabilities.

How it uses Jev

The typed form ( system one ), the HTTP server and GGUF loading are in Quick start.

Getting started

On Apple Silicon, pip install "decider-ai[metal]" adds the optional MLX/Metal kernel. Without it, MPS inference uses the PyTorch implementation.
