About this project
By the same author of the genai crate (Jeremy Chone). Extremely basic functionality / API surface for now. Feel free to cherry pick what you need for now. Part of the zcoder.run Rust libraries, and will probably be used in the zcoder harness (still in the building). Request follows the fluid API style, state accepts impl Into , and questions accept impl Into keyed by impl Into . Request::fromstate(state): state only, no questions yet (Request::new is an alias of it).
Quoted from the project's README. Read the full README.

Highlights
- Builds requests fluently with from_state plus named or indexed questions for noul, choice with criteria, and score with levels.
- Returns a typed response with model id, input and output tokens, computed cost, and per-question typed answers.
- Choice and score answers expose probabilities with confidence, and score answers add the level legend.
- Raw JSON questions are also accepted, so untyped or experimental shapes still pass through.
Watch out
Very early 0.0.x release with a small API surface; confirm the builder and response shapes in the repo before depending on it. Copy reviewed against the repository README on 2026-10-04, not from running it.
Questions about this entry
Short answers drawn from the linked project or page.
It follows the same fluid style as the examples: from_state for state only, with_questions to replace the set, and append_question or extend_questions to grow it. State accepts any JSON value and questions accept typed builders or raw JSON values.
Pass a string for a named wire key or an integer for an indexed q0-style key. Both append_question and extend_questions accept either form, and answer lookup accepts the same key types.
It is computed locally from input tokens at a fixed rate per million tokens for models starting with jev. Other models return no cost, so treat the field as an estimate rather than a billing record.
Treat it as building material rather than a stable dependency. The author calls out the early status and small surface explicitly and invites cherry-picking what you need for now.
Jeremy Chone, by the same author as the genai crate. The README publishes it as part of the zcoder.run Rust libraries and says it will probably be used in the zcoder harness, which is still being built. It is titled an unofficial client and self-describes as a very early 0.0.x release with an extremely basic API surface, inviting cherry-picking.
Dedicated structs with criteria builders: NoulQuestion supports optional with_true, with_false or with_true_false text, ChoiceQuestion takes append_criteria or extend_criteria, and ScoreQuestion takes append_level, extend_levels or a criteria map. Raw serde_json values are still accepted through From<Value> for Question, so untyped or experimental shapes pass through unchanged.
Dual-licensed under either the Apache License 2.0 or the MIT License, at your option, with copyright held by BriteSnow, Inc. for 2026. The README titles it an unofficial client and states it is by the same author as the genai crate, so nothing here is first-party TypeSafe support.

Unofficial Rust client for the TypeSafe AI System One API, matching the Python SDK 0.6.0 contract: named noul, choice and score questions, a typestated builder, per-call overrides, and a `wire` module for serving the same shape.

An unofficial async Rust client for the TypeSafe System One API in which each question hands back a key typed by its answer, so reading a choice answer as a probability fails to compile.

An async Rust client for models served through the System One API: typed Noul, Choice and Score questions go out with one state and typed answers come back, over a single multiplexed HTTP/2 connection with no vendor built in.

Original write-ups on what this entry is for.
Closed weights have not stopped the ecosystem from rebuilding the shape in the open. API-compatible servers, retrained heads on small models, and inference-time tricks that skip generation entirely.
