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 12 GB available to a model on this phone.

At the estimated speed, a roughly 300-word answer may take about 2 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 ~0.2 GB of KV cache and a little speed.
2
Close every other app before loading — the 3.6 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.
