system-one (heyaozh)

An unofficial Rust client for TypeSafe's System One API behind Jev: typed Noul, Choice, Score and Box questions, images, and both async and blocking clients. Its behaviour follows the official Python SDK, with the same environment variables, retry policy and error kinds.

A Python library that turns Jev-style decision models into ordinary function calls: check returns a bool, classify picks one option, label picks every option that applies, and score rates on a scale, with probabilities behind every answer.

Open-source Rust decision engine that turns model judgments into versioned, tested rules: Jev reads text while Ordo decides refunds, discounts and risk thresholds, and shows which decisions a change moves before you ship.

A pure-Rust port of Laya that answers typed questions — choice, score or yes/no — about any text in one batched forward pass, loading checkpoints from the Hugging Face Hub via candle and returning calibrated labels, scores and probabilities with no Python.

A CLI, Rust library and Python package that asks Jev typed Noul, Choice and Score questions through OpenRouter, then turns the probabilities into decisions with fuzzy rules — AND, OR, NOT and hedges into a support score per decision, or a crisp amount — and can draw the rule base as SVG.

An unofficial async Rust client for the TypeSafe System One API, mirroring the shape of the official Python and JavaScript SDKs. It builds noul, choice and score questions with a fluent builder and returns calibrated probabilities.
