  Pluto-2.1 is a 1.738B-parameter standalone typed decision model. It returns
  calibrated probability distributions for choice, noul, and score questions in
  one forward pass. It is initialized from Bosun 3.1 1.7B and Qwen3-1.7B, merged
  into a self-contained checkpoint, and evaluated head-to-head against d1-2B on
  Typed Decisions and a matched DecisionBench subset.
