The Jev model that came out yesterday

Suitable for high-frequency decision-making, so wouldn't that mean it's also suitable for gaming?

Previously used GPT-6 Astra to play Slay the Spire 2 on my behalf

Strong capability but slow speed.

I just tested playing with Jev, action thinking only takes 0.7 seconds,

I couldn't even see the screen clearly before it finished the operation.

This superhuman gaming speed,

Really shocked me into sitting paralyzed again😅

Language is hard to describe this feeling, watch the video⬇️

昨天出的 Jev 模型

适合高频决策,那岂不又是适合打游戏?

之前用 GPT-6 Astra 代打杀戮尖塔2

能力强但速度慢。

我刚实测用 Jev 打,行动思考只需 0.7秒,

画面我都没看清它就操作完了。

这超人类游戏速度,

着实又让我震惊瘫坐了😅

语言很难描述这感觉,看视频⬇️

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x

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.
