Formula estimate
What this means
Our estimate says Qwythos 9B v2 should fit, but replies are likely to arrive slowly.
Download the Q4_K_M version, which is about 5.7 GB. We expect it to use about 7.2 GB of the roughly 9 GB available to a model on this phone.
At the estimated speed, a roughly 300-word answer may take about 3 minutes to finish.

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 1.8 GB headroom is real; Android may kill the app otherwise.
3
Expect throttling after ~10 min of sustained generation on a phone chassis.

Get your first offline chat working
Recommended app: PocketPal. Follow the point-and-click steps below. The speed above is an estimate, not a measurement from this exact app and phone.
1
Install or update PocketPal from Google Play. It is free and does not require an account. Use a current version so its loader supports newer model architectures.
2
Open the exact model. In PocketPal, go to Models → + → Add from Hugging Face, then paste
empero-ai/Qwythos-9B-v2-GGUF.3
Choose the Q4_K_M GGUF file. The download is about 5.7 GB, so use Wi-Fi and keep the app open. Choose the main GGUF weights, not a vision projector, mmproj, or other helper file.
4
Tap Download, then Load. Start with a 4K (4096-token) context. Keep the app’s default Android backend for the first run.
5
Send a simple first prompt. Try “Explain why the sky is blue in three sentences.” This page estimates about 2 tokens/s, but that number is not a PocketPal measurement unless it carries a ✓ Verified label.
6
Confirm it is really offline. After the first reply, turn on airplane mode and ask a second question. If it still answers, the model is running on your phone.
If it does not work
- Model not listed: update PocketPal and paste the exact repository
empero-ai/Qwythos-9B-v2-GGUF. - App closes while loading: close other apps, restart the phone, and try 2K context. If it still closes, choose a smaller model.
- No offline reply: confirm that the Q4_K_M GGUF file is loaded in the chat rather than a remote model.
