@ziwenxu_ explains calling Jev on OpenRouter while TypeSafe still has a waitlist: sign up, add credits, make a key, and POST /api/alpha/decisions with model typesafe/jev-latest, a state, and questions. They cite $0.042 per million input tokens and free output, a billing example at 100% in about a second, and Tetris moves in about half a second.

It's only been out a day and TypeSafe still has a waitlist. OpenRouter has it though, and that's how we've been running it. How Jev or TypeSafe is used, in the post's own words: “Jev is already on OpenRouter!!” The post does not name a separate audience. It is for people reading what @ziwenxu_ shows here (it includes media).
