About this project
typesafe-sdk-go is a Go SDK for the TypeSafe AI API. TypeSafe answers typed questions about a piece of state and returns probability distributions, not prose. There is nothing to parse and no format to coax out of a model. It needs Go 1.25 or newer and has no third-party dependencies. The package is named typesafe, so an import needs no alias in most editors but reads better with one: Set TYPESAFEAPIKEY in your environment, then: There is a runnable version in examples/demo:
Quoted from the project's README. Read the full README.

Highlights
- Installs with go get, needs Go 1.25 or newer, and has no third-party dependencies.
- Sends Noul, Choice, and Score questions in one call, evaluated in parallel and in isolation.
- Validates requests locally before sending and exposes Validate for early checks.
- Client is safe for concurrent use, pools connections, and reads the key from TYPESAFE_API_KEY.
Watch out
Needs a TypeSafe API key and network access; debug bodies are not redacted and may hold evaluated data. 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 client-side validation, typed answer accessors with clear type errors, retries with backoff, error classes, and connection pooling, while the HTTP API leaves all of that to you.
You do. A Noul answer is a probability with no Yes method on purpose, because only you know what a wrong yes and a wrong no cost in your application.
No. Timeout bounds each attempt only, so wrap the call in a context with timeout when you need a whole-call budget; retries honor Retry-After within a minute.
No. Redirects return an APIError with the original 3xx status so credentials and evaluation data are never forwarded, unless you supply an explicit CheckRedirect policy.
Run go get github.com/Tangerg/typesafe-sdk-go@latest. It needs Go 1.25 or newer and has no third-party dependencies. Set TYPESAFE_API_KEY and construct the client with typesafe.NewClient(nil); the package is named typesafe, so most imports read better with an alias.
Accessors are named at the point of use: result.Answers.Noul("isBilling"), .Choice("tone") and .Score("urgency") each return a typed answer or a clear error when it is absent or the wrong type. A choice carries the selected label and its own probability, a score carries the expected value, the level it rounds to and that level's description, and a noul is the raw probability.
TYPESAFE_BASE_URL defaults to https://api.typesafe.ai and TYPESAFE_DEFAULT_MODEL to jev-latest, and a blank environment value counts as unset. DefaultRetryPolicy retries 408, 429 and every 5xx plus connection failures and timeouts, twice each, with exponential backoff from 500ms to 5s and up to 25% jitter, honoring a Retry-After header within a minute.

Go client for the TypeSafe API with typed question and answer types, per-request model and timeout overrides, request-body passthrough for fields the SDK does not model, and slog diagnostics that exclude bodies and credentials.

Unofficial Go client for the TypeSafe System One API, aiming for 1:1 parity with the official JavaScript and Python SDKs: typed Noul, Choice and Score, status-specific errors, and an injectable http.Client.

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.

Unofficial Go SDK for TypeSafe AI's System One API, kept deliberately minimal: one client, a state map, a map of typed questions, and answers read back by question id.

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.
