Can OneJev 4B run on vivo Y600i?

Estimated weights fit · custom workflow required

Weight fit is not phone app support

The tracked IQ4_XS weights are 2.9GB; the generic working-memory estimate is 3.9GB against 4GB usable. Image inputs need additional projector memory.

OneJev scores typed decisions in a single forward pass, not chat replies. The decode estimates below are not measured decision latency. The publisher's qev server and System One client are required; AICanRun has not verified a phone app route.

Make it bearable

1
Drop context to 2K — saves ~0.2 GB of KV cache and a little speed.
2
Close every other app before loading — the 0.1 GB headroom is real; Android may kill the app otherwise.
3
Expect throttling after ~10 min of sustained generation on a phone chassis.

Use the right workflow for this model

The model fits in memory, but it is not an ordinary chat model.

This model is designed to return calibrated probabilities for typed choices from text or images. PocketPal does not provide the required the publisher's qev server and System One client; image inputs also need a vision projector, so the tracked file is not a beginner phone-chat path.

If you only want a normal private chat, use this simpler model instead:
