What it is
The decision-model interface for Ruby. Decision models answer typed questions about a state with calibrated probabilities instead of generating text. This gem talks to them through one Client with a provider behind it. OpenRouter is the default. Typesafe (Jev), OpenAI (gpt-6-luna), Cloudflare (Clef), Perplexity…
Getting started
From the README:
gem "ruby_decision_model"Where the decision sits
ruby_decision_model calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.
Models it references: Jev, Alpha.
How active it is
Created 2026-09-18, last pushed 2026-10-12, 59 stars and 6 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.
