JEV IS FREE ON VERCEL UNTIL SEPT 25, AND YOU CAN SKIP THE WAITLIST 😳 it hit 13% of teams on the gateway in its first day, 2x the gpt-5.6 family and 6x fable 5.1 it is not a chatbot. it makes decisions. you describe the situation and give it a few fixed options, it picks one and tells you how sure it is, so instead of writing text it returns: - choice: which option it picked, and how sure it is - score: a rating on your own scale - boolean: a yes or no, with a percentage so routing stops being a prompt and becomes code you own: if (answer.choice === "other" || answer.confidence < 0.8) { manualTriage(); } else { routeTo(answer.choice); } one call answers several questions against the same state, so a decision step costs cents and runs in milliseconds how to run it free from vercel (5 min): 1. make a vercel account, then create an ai gateway key in the dashboard 2. export AI_GATEWAY_API_KEY="your_key" 3. pnpm add ai@latest 4. call evaluate with model "typesafe-ai/jev", your state and your questions tools people already built on it: - browser-use/jev-ultrafast: a browser agent that only calls an llm when it has to type (5.8k stars) - awlevin/typesafe-computer-use: ocr the screen, pick the next click, about $0.0002 a step - devagrawal09/jev-review: staged code review that grades a diff for correctness and risk - gargpratyush/jev-router: routes each claude code turn to the cheapest model that fits - Anil-matcha/awesome-jev-by-typesafe: the community bank of patterns, prompts and starter code one thing on free: vercel's docs say free gateway credits may need a payment method on the team, so set that up before you start type safe is not the same as accurate, so measure your routing quality and how often it escalates i will drop link in comment
