Can Fara 1.5 27B run on ROG Phone 9 Pro?

YESRuns, barely
Formula estimate

What this means

Our estimate says Fara 1.5 27B should fit, but there is very little memory left for the operating system and other apps.

Download the Q4_K_S version, which is about 16.5 GB. We expect it to use about 19.8 GB of the roughly 20 GB available to a model on this phone.

At the estimated speed, a roughly 300-word answer may take about 3 minutes to finish.

This result is calculated from the phone and model specifications. It has not been measured on this exact phone and setup.

Make it bearable

1
Drop context to 2K — saves ~1 GB of KV cache and a little speed.
2
Close every other app before loading — the 0.2 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 operate websites from screenshots as a computer-use agent. PocketPal does not provide the required a browser-control harness that repeatedly supplies screenshots and executes the model's actions, so the tracked file is not a beginner phone-chat path.
