What it is

Reproduction kit for the Decision Index, a benchmark for typed decision engines: models that take a state and a set of typed questions (multiple-choice choice or yes/no noul primitives with explicit criteria) and return one answer per question with a probability for every supplied option. It lets anyone rebuild the…

Getting started

From the README:

pip install -e ".[transformers,rebuild]"
export HF_HUB_DISABLE_XET=1
python -m decision_index suite rebuild --work work
python -m decision_index suite import \

Where the decision sits

How active it is

Created 2026-09-22, last pushed 2026-10-20, 83 stars and 144 forks when we read it on 2026-11-02. Everything in this category is weeks old at most, so a stale push date means something different here than it would on a mature project. Check the repository before you depend on it.

Find out what your data actually supports

We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
