Formula estimate

What this means

Our estimate says Ternary Bonsai 27B should fit, but replies are likely to arrive slowly.

Download the Q2_0 version, which is about 7.2 GB. We expect it to use about 8.4 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 83 seconds 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 ~0.2 GB of KV cache and a little speed.
2
Close every other app before loading — the 11.6 GB headroom is real; Android may kill the app otherwise.
3
Expect throttling after ~10 min of sustained generation on a phone chassis.

The model fits in memory, but this exact download is not a PocketPal model.

The current App Store and Play Store versions of PocketPal cannot load this tracked ternary file. Memory fit does not make this exact download beginner-ready.
