Show HN: Qwen 3.5 running on a $300 Android phone – on-device, open source
Qwen 3.5 Small dropped two days ago. I had it running on a mid-tier Android phone within hours.
It's great seeing the on-device AI community light up around this release. Off Grid brings it to Android: phones with 6GB RAM in the $200-300 range, ~8 tok/sec on the 2B model. Fully offline.
Text generation, vision AI, image gen, voice
transcription, tool calling, document analysis — all on-device, nothing uploaded, ever. Works in airplane mode.
780+ GitHub stars. ~2,000 downloads across Android and iOS. Early days.

- ucguy4u 7mo agoThe current copy function copies the entire message. Could it please be improved to allow selection and copying of only the desired text?
- ali_chherawalla 7mo agofair point, let me know work on that. That's a small lift.
- alefiyakachwala 7mo agoCan you share some technical details? How did you do it? What’s under the good?
- ali_chherawalla 7mo agoofcourse ofcourse, I've documented everything here: https://github.com/alichherawalla/off-grid-mobile-ai/blob/main/docs/ARCHITECTURE.md https://github.com/alichherawalla/off-grid-mobile-ai/blob/ma... llama.cpp compiled as a native Android library via the NDK, linked into React Native through a custom JSI bridge. GGUF models loaded straight into memory. On Snapdragon devices we use QNN (Qualcomm Neural Network) for hardware acceleration. OpenCL GPU fallback on everything else. CPU-only as a last resort. Image gen is Stable Diffusion running on the NPU where available. Vision uses SmolVLM and Qwen3-VL. Voice is on-device Whisper. The model browser filters by your device's RAM so you never download something your phone can't run. The whole thing is MIT licensed - happy to answer anything about the architecture.
- mwze 7mo agoAny roadmap to add Mediatek NPU support?
- ali_chherawalla 7mo agoI'm working on that we speak. Shouldn't not be that difficult of a lift and should be able to do that tonight or in the next couple of nights
- mwze 7mo agoHappy to test, I have poco X6 pro, 12gb ram model
- ali_chherawalla 7mo agoawesome. I'll let you know once thats in
- ruthlesssavage 7mo agoYou have eliminated the problem of latency and having flagship phones. Amazing, my old android has AI now. Gave you star on github. Ciao.
