Jev Ruby

Ruby-native AI framework whose RubyLLM::Judge class asks typed judgment questions: a probability that a statement holds, choices or scores, answered by the TypeSafe provider alongside 18 other hosted and local providers under one consistent API.

A Ruby client for TypeSafe's System One API that returns typed Noul, Choice, and Score answers, validates obvious input mistakes before spending a request, and pools HTTP connections across threads.

A Ruby client for Noul, Choice, and Score decision models, reaching OpenRouter by default or TypeSafe's native API, with no runtime dependencies beyond the standard library.

A RubyLLM 2 provider that adds Jev through structured output: build Noul, Choice, and Score questions with a schema builder, pass them to chat.with_schema, and read typed answers from response.parsed.

A community Rails integration built on the typesafe-sdk Ruby gem that adds Rails configuration, persisted usage and cost telemetry, and persistence-backed confidence policies for Choice and Score answers.
