Opposable: on-device AI that operates your Android phone
Android app that reads the screen through the accessibility service and taps and types in any app; when no cloud model is connected, Alibaba's GUI-Owl 1.5 2B screen model runs the whole agent loop on the phone with no server.
Why it matters
True on-device computer-use: the 2B model (Qwen3-VL fine-tune) runs via llama.cpp, with the vision encoder offloaded to the Galaxy S25 NPU at 236 ms per screen.
What you could build with it
A startup serving field workers in low-connectivity regions could ship a white-label on-device phone agent that guides users through app workflows offline, with no cloud calls and no data leaving the device.
Does it hold up?
Evidence is the team's own measurements: 7.3 s per step on an M2 CPU, 236 ms vision encoding on a Snapdragon NPU, and 6 of 16 held-out tasks succeeding. Too early to judge general reliability.
