I built a browser extension with Jev @typesafeai that can hide/collapse posts on X based on natural language. It's so fast that it's not noticeable and insanely cheap...this must be the future of "ad blockers" and content firewalls.
API & Models
Noul-only model
A local decision model that answers yes/no questions and rejects Choice and Score instead of guessing a shape.

Definition
jevos serves Jev's JSON and returns a noul probability between 0 and 1. Choice and Score questions get HTTP 422. Optional criteria are accepted and not read. The README lists multiple choice and scores as not yet available.
A client that sends a mixed question map will fail the whole request. Split yes/no traffic onto a Noul-only server only when every question in the call is a Noul, or keep Choice and Score on a server that implements them.

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
Jev plays Slay the Spire 2
昨天出的 typesafe.ai 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⬇️

Jev + Kimi K3 for fraud detection! TLDR: Jev classified 100 emails in 1.42 seconds, then I routed the uncertain cases to Kimi K3. The full pipeline got 96/100 correct for only ~$0.07. Video is not sped up, check out the live run! Here was my process: I gave Jev 100 emails to Show more
