OneJev1.6-9B is the 9B 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/Qwen3.5-9B](https://huggingface.co/Qwen/Qwen3.5-9B) 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](https://huggingface.co/spaces/multimodalart/jev-decision-index) (37 benchmarks, 140,178 requests, run and scored with the board's own kit), OneJev1.6-9B scores 65.31, up from 59.03 for OneJev1.5-9B. That is sixth of the 172 models on the board, and the five models above it all have 26B parameters or more. It has the best score in four of the five areas among the five models below.
The four other models are the highest-scoring models of 6B to 12B parameters on the board.
It also scores above 52 of the 57 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
```bash
uv venv -p 3.12 && source .venv/bin/activate
uv pip install flide torchvision
flide serve --model OmniJev/OneJev1.6-9B
```
In another terminal, run this example with your own `screenshot.png`:
```bash
IMG=$(base64 -w0 screenshot.png)
curl http://localhost:8000/v1/systemone -H "Content-Type: application/json" -d @- <"},
"media": [{"type": "image", "data": "data:image/png;base64,$IMG"}],
"questions": {
"done": {"type": "noul", "instructions": "The invoice has been paid"},
"next": {"type": "choice", "instructions": "What should the agent do next?",
"criteria": {"click": "click an element", "type": "type text", "scroll": "scroll", "stop": "stop"}},
"progress": {"type": "score", "instructions": "How far along is the task?",
"criteria": ["not started", "halfway", "almost done", "done"]}
}
}
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.
