YES — Runs, barely
Grade C · 47/100 · formula estimate
What this means
Our estimate says Llama 3.1 8B should fit, but there is very little memory left for the operating system and other apps.
Download the IQ4_XS version, which is about 4.4 GB. We expect it to use about 5.8 GB of the roughly 6 GB available to a model on this phone.
At the estimated speed, a roughly 300-word answer may take about 4 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 ~0.3 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.
