got @typesafeai’s new model Jev to play Super Mario Bros.
Ran Super Mario Bros. with Jev as the controller, relying on fast inference and structured outputs for real-time play.

got @typesafeai’s new model Jev to play Super Mario Bros.
fast inference + structured outputs makes it surprisingly good for real time use cases.
I'm excited to see what can be done with these new models!
From the same thread
- @kzkhykw — 今めっちゃバズってる @typesafeai の新しいAIモデル「Jev」にマリオを操作させてるけど人間にプレイにしか見えない。驚き屋にならざるを得ないというか このJevまだ勉強途中なんですが、シンプルだけど画期的で、通常のLLMは確率でテキストを生成する仕組みだけど、Jevはテキストそのものではなく、確率付きのテキストの配列みたいな構造化データを並列に提示する仕組みっぽい

Numbers are a snapshot taken from X when the case was added to the library (schema v1, collected 2026-09-19); they will not match today.
Where this case fits
Filed under general Jev builds. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Browse the full case library for the work it sits next to.
