Decision Index 0.3, public suite: 59.73 (our scoring with the kit), against 53.64 for autotrust/JEV-27B-VL on the board. Approximate public vision score 71.94 (our rebuild of the vision benchmarks; JEV-27B-VL 71.67 on the same rebuild, a tie within noise). Median single-request latency 204 ms on one B200 (JEV-27B-VL 271 ms).
[!TIP] NVFP4 version: autotrust/JEV-35B-NVFP4, the same model with its routed experts in NVFP4: 25.6 GB download, 23 GiB of GPU memory (bf16: 72 GB, 66 GiB), so it runs on one 32–48 GB GPU. Decision Index 0.3 public 59.18 (bf16 59.73), vision rebuild 71.23 (bf16 71.94), 96.6 % of the Decision Index answers identical to bf16, same latency, same
serve.shand API.
Two models, two organisations. TypeSafe Jev 1.13 is the hosted, closed model made by TypeSafe AI. autotrust/JEV-35B is an independent open-weights model built by AutoTrust AI; it is not affiliated with, endorsed by, or a product of TypeSafe AI.
JEV-35B: all 140,178 scoreable requests of the 0.3 public suite answered (0 errors), System 1 only (thinking off),
every choice read in one pass (up to 256 options), scored with the kit's score --edition 0.3. Our scoring, not a board
entry: the board's Full score also counts private tests (80 %), which only its maintainers run. JEV-27B-VL: the board's
public numbers for JEV-27B, whose text decisions JEV-27B-VL reproduces (see the JEV-27B-VL card).
JEV-35B is ahead in all five areas and on 24 of 37 benchmarks. Largest gains (skill points): PhishNChips +42.2, HoVer +28.4, Habermas Machine +28.1, VAST +22.7, WinoGrande +18.9, BANKING77 +18.3, iSarcasmEval +17.2, When2Call +14.9, GPQA +9.5. JEV-27B-VL is ahead on POP909-CL (+25.8), GSM8K (+18.2), ANLI (+11.4), BPoMP (+10.9), NLI4CT (+6.8) and BBH (+4.7).
Skill rescales the benchmark's own metric so that chance is 0 (below chance counts as 0); ★ = gold benchmark (weight 1.2); the higher score is in bold.

The vision benchmarks of the Decision Index are not published; this is our rebuild of their public datasets (CV-Bench, BLINK, RealWorldQA, CharXiv, InfographicVQA, Mind2Web, CORD + FUNSD, Hateful Memes, R-Bench-M, MMMU-Pro vision; Winoground not included), scored with the board's chance correction and weights. The same rebuild gives JEV-27B-VL 71.67 against its board score of 71.53 on the same benchmarks.
Overall the two models are level: the difference (+0.3) is inside the noise (paired bootstrap 95% interval −0.9 to +1.4). The only statistically significant per-benchmark difference (paired McNemar test, p < 0.01) is moderation, in favour of JEV-35B (+10.4); MMMU-Pro (+3.1, p = 0.03) also leans to JEV-35B. The small deficits on RealWorldQA, R-Bench-M, CharXiv, InfographicVQA, CV-Bench and BLINK (−1 to −4) are not significant. The vision tower is Qwen3.5-35B-A3B's; image decisions are zero-shot.
One sequential client, the same 587 rows (387 text rows sampled across the Decision Index, 200 image rows), POST
/v1/decide on serve.sh (vLLM), one B200:
Same demo code, seeds, scenes and opponents as the JEV-27B-VL card; every
step is one System 1 decision (POST /v1/decide, thinking off), one model on one B200.
Computer use: screenshot → which element to click. A real browser (headless Chromium). Every clickable element gets a numbered box; System 1 picks the next click (or "the task is complete"), the browser clicks it, and the loop repeats.
Robot arm: pick and place from a camera image (MuJoCo). At every step System 1 answers two questions from the top camera: is the target left or right of the gripper, and above or below it? The arm halves its step whenever an answer flips.
Games (seed 0 for both models; board as image + text):
For game play, use JEV-27B-VL. Over five seeds JEV-35B's largest 2048 tile averages 64 (random play: 102), it passes
no Flappy Bird pipe and eats 3–18 pieces of food in Snake (mean 10). Per-episode results: reports/demos/ [blocked].
On a smaller GPU, use autotrust/JEV-35B-NVFP4 (one GPU with 32 GB or
more; same serve.sh and API):
serve.sh runs serve_decide.py: the standard vLLM OpenAI server (same flags as vllm serve) with a POST /v1/decide
route. The decision model is merged into the weights, so vLLM loads one plain checkpoint, with no LoRA. Tested with a
vLLM development build from September 2026.
POST /v1/decideThe response has options, probabilities, choice, choice_index and usage. GET /v1/decide/info lists the
defaults.
If you call vLLM's /v1/completions yourself instead of /v1/decide, pass top_k: 0 and top_p: 1.0 so that the
returned probabilities are not truncated, then add the head bias and apply the temperature as below. JEV-35B is a decision
model only: it does not chat or generate text.
System 1 reads the hidden state at the last token of a bare-text prompt:
A 264-slot decision head gives one logit per slot; the active slots of the question's kind are soft-maxed with a
per-kind temperature (calibration.json). The head is merged into the lm_head rows of the slot tokens (A–JU,
false/true, 0–5); serve_decide.py adds the head bias (adapter_vllm/decision_head.json) and the temperature.
