modelsystem
Public contribution repo for modelsystem.one, a curated catalog of System One decision models such as Jev.
This repository is mostly documentation or write-up rather than runnable code.
Overview
ModelSystem.One is a curated catalog of System One or decision models: AI systems that return typed decisions (choice, score, boolean) with calibrated probabilities rather than free text. This GitHub repository is the public contribution surface for issues, PRs and discussions; the website application itself is in a private repository.
The site offers a model catalog, a maturity-by-capability quadrant, learning material on System 1 versus System 2, integration guides, news with RSS and a spec of inclusion criteria: the primary interface must return typed decisions, the model must be publicly available, and it needs minimum API documentation. It notes that Jev currently leads the category and that it is independent and not affiliated with TypeSafe. It is useful for anyone surveying decision-model options. A Portuguese version is available.
