Jev access channels compared

There is one System One evaluation contract. There are several doors. Model IDs, auth headers, and free-tier rules are not portable. This matrix is an independent snapshot dated 2026-09-21 — re-check the linked vendor pages weekly. jev.pro is not affiliated with TypeSafe AI and does not sell keys. Canonical first-party truth: docs.typesafe.ai.

Channel matrix (as of 2026-09-21)

Door	Auth you send	Model ID you send	How you call it	Free-tier / access caveat	Who documents it
TypeSafe HTTP	`Authorization: Bearer` TypeSafe key	`jev-latest`, `jev-preview`, or pin `jev-1.13.0`	`POST https://api.typesafe.ai/v1/systemone`	Early-access waitlist (launch post, 15 Sep 2026). No self-serve free tier on the public models page.	API reference, models
TypeSafe Python SDK	`TYPESAFE_API_KEY`	Defaults to `jev-latest`	`pip install typesafe-sdk` (Python ≥ 3.10)	Same waitlist as first-party HTTP. SDKs retry 429/529.	SDK
TypeSafe JS SDK	`TYPESAFE_API_KEY`	Defaults to `jev-latest`	`npm i @typesafe-ai/sdk` (Node 20+)	Same as Python SDK.	JS SDK
Playground	Console login	Playground picker	Browser only	Needs a console account.	Quick start
Agent skill	Your key, used by the agent	Per skill docs	Claude Code plugin or `npx skills add typesafe-ai/skills`	Skill does not issue keys.	Agent skill
Vercel AI Gateway	Gateway key or Vercel OIDC	`typesafe-ai/jev`	Gateway + AI SDK `experimental_evaluate`; base often `https://ai-gateway.vercel.sh/typesafe`	Vercel account rules. Local OIDC expires (~12h in Vercel’s KB). Promos expire — check Vercel, not this table.	Vercel KB, model card
OpenRouter Decisions	`Authorization: Bearer` OpenRouter key	`typesafe/jev-1.13`	`POST https://openrouter.ai/api/alpha/decisions` (not the chat-completions URL)	Needs OpenRouter credit. 402 is an OpenRouter billing error, not TypeSafe’s documented set.	OpenRouter model page
Cloudflare Workers AI	Account token / Worker `env.AI`	`typesafe/jev`	`env.AI.run('typesafe/jev', { state, questions })` or REST `…/ai/run`	CF dashboard pricing. Card lists 32k context — narrower than TypeSafe’s 64k request budget.	CF model page
LangChain	`TYPESAFE_API_KEY`	Classifier default	`langchain-typesafe`, `TypeSafeClassifier`	LangChain APIs can move.	LangChain post

Vendor price claim (first-party): TypeSafe lists Jev 1.13 at $0.042 / million input tokens, output free. OpenRouter’s card repeats $0.042 / $0. Vercel’s model card repeats $0.042 / 1M input. Cloudflare says “view pricing in the dashboard.” Gateway or marketplace fees are that vendor’s invoice.

Differences that bite

jev-1.13 vs jev-1.13.0. First-party docs pin the versioned id jev-1.13.0. Aliases are jev-latest / jev-preview. OpenRouter’s public id is typesafe/jev-1.13. Do not paste one name into the other door.
Boolean vs Noul. Vercel AI SDK examples use type: "boolean" and a probability field. First-party HTTP uses noul. Do not copy-paste schemas across doors.
Context cards disagree. TypeSafe models page: 64k combined / 32k state+longest question. OpenRouter and Cloudflare cards we fetched list 32k. Believe the door you are calling.
Retries. Official TypeSafe SDKs honor retry-after on 429/529. Raw HTTP, Gateway, OpenRouter, and Workers AI need your backoff — and may emit their status codes (402, customer verification).
Chat SDKs. OpenRouter itself says chat-completions SDKs will not work on the Decisions API.

Pick one production door. Log the resolved model from the response (jev-1.13.0 on first-party examples).

FAQ

Which door should I use this week? If you have a TypeSafe console key: first-party HTTP or SDK. If you only have Vercel/OpenRouter/CF credentials: that door’s docs. jev.pro will not pick a reseller for you.

Is there a free tier? TypeSafe’s public models page does not describe one. Third-party promotions expire. Treat “free” as a dated vendor claim.

Do you issue keys? No.
