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
pip install "qev[torch] @ git+https://github.com/OmniJev/OneJev.git"qev serve --model OmniJev/OneJev1.5-9B
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 and the code are on GitHub.
