OneJev1.6-27B is the 27B model of OneJev 1.6, a multimodal System One decision model. Give it a screenshot, a photo, a video or plain text along with a few typed questions, and it returns a calibrated probability for every option in a single forward pass. It is a full fine-tune of Qwen/Qwen3.8-27B on about 440,000 questions drawn from real agent runs, videos, images and the training splits of public decision datasets.
Decision Index
On the public part of Decision Index 0.3 (37 benchmarks, 140,178 requests, run and scored with the board's own kit), OneJev1.6-27B scores 69.49, up from 63.64 for OneJev1.5-27B. That is second of the 172 models on the board, level with KnowLine 35B-A3B Gen1.
The four other models are the highest-scoring models of 25B to 36B parameters on the board.
Other models' scores are their public-part scores on the board on 16 October 2026.
Results
Accuracy in percent. The OneJev test set holds questions of the training kinds that no model saw in training. Jev 1.13's scores are its published ones, and it reads text only.
Quick start
uv venv -p 3.12 && source .venv/bin/activate
uv pip install flide torchvision
flide serve --model OmniJev/OneJev1.6-27B
In another terminal, run this example with your own screenshot.png:
IMG=$(base64 -w0 screenshot.png)
curl http://localhost:8000/v1/systemone -H "Content-Type: application/json" -d @- <<EOF

answers.done.noul is the probability of yes, answers.next.probabilities gives one probability per option and answers.progress.score is the expected level.
Flide serves TypeSafe's System One API plus a media field for images and video. More examples are on GitHub.
