A week of JEV at AutoTrust AI: from fast text decisions to open multimodal action loops.
JEV is our System 1 family for agents.
Instead of generating a paragraph before every small action, JEV returns calibrated probabilities for yes/no, 2–16-way choice, and 0–5 scoring — so an agent can act immediately, or escalate hard cases to System 2 reasoning.
The foundation is our Blocks of Experts (BoE) recipe: keep a capable base model intact, add a small decision expert, and route each request to the right path. Fast decisions and deeper reasoning, served from one engine.
What we have released:
• JEV-9B — our first integrated open System 1 + System 2 model. It reaches ≈0.019 KL to TypeSafe Jev 1.13’s decision distributions, while making a decision in about 90 ms median on one B200. Its System 1 block trains only 40.2M parameters — 0.5% of the backbone.
• JEV-27B — our stronger 27B model. It reaches ≈0.017 KL, achieves 96% of Jev’s accuracy on an independent 16-option benchmark, and scores 84.07% across six public decision benchmarks in our updated evaluation, ahead of Jev 1.13’s 83.85% in 4 of 6 groups. Its System 2 path remains unchanged at 78.0% HumanEval, while System 1 runs at 137 ms median per decision on one B200.
• JEV-Gemma4-26B-A4B — a BoE System 1 + System 2 bundle on Gemma 4 MoE. It scored 58.05 on Decision Index 0.2.1, completing all 150,317 scored requests with 0 errors and 0 unsupported.
• JEV-27B-VL — what we believe is the world’s first open-weight, near-SOTA multimodal decision model. It extends calibrated decisions to images and visual state: Mario, Tetris, and Rubik’s Cube are not chat demos; they are see → decide → act loops.
Across the JEV family, the goal is the same: give agents a fast, calibrated System 1 for high-frequency judgments — without giving up the System 2 reasoning needed for hard work.

Introducing JEV-27B-VL.
We believe it is the world’s first open-weight, near-SOTA multimodal decision model — built with AutoTrust AI’s Blocks of Experts (BoE) recipe.
It does not just describe what it sees. It turns visual state into calibrated action probabilities, then selects what to do next.
In this demo, it sees Mario’s position, movement, obstacles, and timing — then chooses whether to run, jump, or do both.
See → decide → act.
