About this project
Go client for the TypeSafe AI System One API (jev models). Send a state and a map of typed questions (Noul, Choice, Score), get typed answers back — in one call. The library imports only the standard library (testify is used in tests only). resp.Model is the versioned model that answered (e.g. jev-1.13.0), resp.Usage holds token counts, resp.RequestID the x-typesafe-request-id header.
Quoted from the project's README. Read the full README.

Highlights
- Installs with go get, needs Go 1.24 or later, and imports only the standard library outside tests.
- Builds Noul, Choice, and Score questions in code with typed accessors for answers, probabilities, and confidence.
- Unknown server-side answer types decode into UnknownAnswer with raw JSON instead of breaking code.
- Configures key, base URL, model, timeout, and retries via options or env vars, with per-call overrides.
Watch out
Unofficial community SDK with no TypeSafe affiliation; needs a TYPESAFE_API_KEY and live integration tests spend tokens. 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 adds typed question builders and answer accessors, env-based configuration with per-call overrides, a default retry policy matching the official SDKs, and APIError sentinels you match with errors.Is.
Answers of an unknown type decode into UnknownAnswer carrying the raw JSON, so a new server-side primitive does not break existing code; you handle the raw payload until the SDK adds a typed accessor.
The default policy makes 2 retries with 0.5s to 5s exponential backoff plus jitter, retries 408, 429, and 5xx including overload plus connection errors and timeouts, honors Retry-After up to 60s, and stops before exceeding a 30s total budget.
HTTP failures return APIError with status, body, headers, and request ID; match errors.Is against ErrRateLimited for 429, ErrOverloaded for overload, ErrAuthentication for 401, ErrUnprocessableEntity for 422, and ErrTimeout or ErrConnection for transport failures.
Go 1.24 or later, and it imports only the standard library outside tests (testify is used in tests only), so there is no third-party runtime dependency to audit.
Call client.ListModels(ctx), which returns each model's name, release date, and description; the answering model is also reported per call in resp.Model as a versioned id such as jev-1.13.0.
resp.RequestID carries the x-typesafe-request-id header and resp.Usage holds token counts, so you can correlate a call with provider logs and track spend.

An unofficial Go client that keeps Jev answers in your own types, so a choice over your enum yields that enum and the compiler checks the switch you write on it.

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.
