OneJev1.6-0.8B is the 0.8B 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 averages the weights of three full fine-tunes of Qwen/Qwen3.5-0.8B, trained on 390,000 to 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), OneJev1.6-0.8B scores 48.82, up from 42.71 for OneJev1.5-0.8B. That is the highest of any model up to 2.5B parameters on the board, and it leads its class in all five areas.
The four other models are the highest-scoring models of up to 2.5B parameters on the board.
It also scores above 47 models of 4B parameters and more 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/OneJev1.6-0.8B
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.
