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.
On one H200 with a 1280x720 screenshot, OneJev-27B answers 1 question in 189 ms and 10 questions in one request in 324 ms (32.4 ms per question).
Quick start
pip install "qev[torch] @ git+https://github.com/OmniJev/OneJev.git"qev serve --model OmniJev/OneJev-27B
from qev import Client, Choice, Noulfrom qev.media import data_uri r = Client("http://localhost:8000").system_one( state={"task": "Pay the open invoice from ACME", "screen": "<image:1>"}, 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 and video. More examples, the latency
benchmark and the code are on GitHub.
OneJev-27B also runs on llama.cpp from the GGUF build by mradermacher,
without PyTorch. Images work there; video needs the PyTorch server.
