Jev vs dJev
dJev is a hosted decision model built for speed and images. Jev is a hosted text model for choice, score and yes/no, with a probability on each option.
What dJev is
dJev, from Maisa, is a hosted decision model based on DiffusionGemma. It accepts images as well as text, and its public materials emphasize short latency. It is a separate product from Jev, with its own account and its own preview terms.
What you are choosing
Jev stays on text. One request carries a shared state and several named questions. Each answer is one of the options you listed, plus a probability. dJev is the one to try when the decision is about a picture or a camera frame. Read its own notes on whether those probabilities are calibrated before you auto-approve anything.
What this site runs
JEV Gateway calls Jev. We do not resell dJev. If the decision needs an image, call dJev directly. If your code needs a text decision it can threshold, call this API.
