TypeSafe
Company behind the System One model category and jev. Per the announcement read in jev-is-incredible: founded by an ex-OpenAI researcher the transcript renders as “Dio”. He worked on the methods behind ChatGPT instruction-following and on RLHF. He left convinced chat models were missing something big about automation, and the company spent two years in stealth before the Jev release. The company name is the claim: the output shape is a type contract the model honors.
Distribution as of the video: invite-only early access for Jev, reachable through OpenRouter and the Vercel AI Gateway.
