This repository holds GGUF files of [OneJev1.6-27B](https://modelscope.cn/models/OmniJev/OneJev1.6-27B) for llama.cpp.
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](https://huggingface.co/Qwen/Qwen3.8-27B) on about 440,000 questions drawn from real agent runs, videos, images and the training splits of public decision datasets.
## Files
Converted with [llama.cpp](https://github.com/ggml-org/llama.cpp/commit/23f7aabc16c72f6f707dba227251c35d7bd1ed96) from the released weights of [OneJev1.6-27B](https://modelscope.cn/models/OmniJev/OneJev1.6-27B).
| File | Size | |
|---|---|---|
| `OneJev1.6-27B-Q4_K_M.gguf` | 16.5 GB | smallest, for low memory |
| `OneJev1.6-27B-Q5_K_M.gguf` | 19.2 GB | |
| `OneJev1.6-27B-Q6_K.gguf` | 22.1 GB | |
| `OneJev1.6-27B-Q8_0.gguf` | 28.6 GB | recommended, closest to the original |
| `mmproj-OneJev1.6-27B-F16.gguf` | 928 MB | vision projector, needed for images |
## 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), OneJev1.6-27B 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
Install [llama.cpp](https://github.com/ggml-org/llama.cpp/blob/master/docs/install.md) first (`brew install llama.cpp` on macOS), then download one model file and the vision projector and serve them with qev.
```bash
pip install modelscope git+https://github.com/OmniJev/OneJev.git
modelscope download --model OmniJev/OneJev1.6-27B-GGUF OneJev1.6-27B-Q8_0.gguf mmproj-OneJev1.6-27B-F16.gguf --local_dir OneJev1.6-27B-GGUF
qev serve --gguf OneJev1.6-27B-GGUF/OneJev1.6-27B-Q8_0.gguf --port 8000
```
qev finds the vision projector next to the model file and fetches the tokenizer from Hugging Face. Without Hugging Face access, download the tokenizer from ModelScope and pass it with `--tokenizer`.
```bash
modelscope download --model OmniJev/OneJev1.6-27B --include "*.json" "*.jinja" --local_dir OneJev1.6-27B
qev serve --gguf OneJev1.6-27B-GGUF/OneJev1.6-27B-Q8_0.gguf --tokenizer OneJev1.6-27B --port 8000
```
```python
from qev import Client, Choice, Noul
from qev.media import data_uri
r = Client("http://localhost:8000").system_one(
state={"task": "Pay the open invoice from ACME", "screen": ""},
media=[{"type": "image", "data": data_uri("screenshot.png")}],
questions={"done": Noul("The invoice has been paid"),
"next": Choice("What should the agent do next?", {"click": "click an element", "stop": "stop"})},
)
```
The server speaks TypeSafe's System One API plus a `media` field for images. For video, use the PyTorch weights in [OneJev1.6-27B](https://modelscope.cn/models/OmniJev/OneJev1.6-27B). More examples and the code are on [GitHub](https://github.com/OmniJev/OneJev).
