Guide

I've been researching on-device AI deployment on Android. Key findings:

The 2026 Android on-device AI stack

LiteRT 2.3 (formerly TensorFlow Lite): default runtime, CompiledModel API, NPU/GPU/CPU auto-negotiation
MediaPipe Tasks: production-ready vision/audio detection (hand, pose, face, object, audio)
Gemini Nano / ML Kit GenAI: platform LLM on supported devices (summarization, proofreading, rewriting, image description)
ONNX Runtime Mobile: PyTorch-first, iOS+Android parity
ExecuTorch 1.5: now stable (no longer experimental), PyTorch-native

Three promises on-device AI keeps that cloud cannot

Privacy: sensitive data never leaves the phone (HIPAA/GDPR/PCI-DSS shorthand)
Latency: sub-100ms predictable (no 50-300ms cloud round-trip)
Offline: works in airplane mode, tunnels, dead zones

Cost math: on-device vs cloud

100K MAU fitness app, 30 inferences/day = 3M/day
Cloud: $6,000/day = $180K/month = $2.16M/year
On-device: ~$600/month recurring + one-time build
Break-even: past ~100K users at 10+ inferences/day

Decision framework: 5 questions

Latency-critical (<200ms)? → on-device
Sensitive data (biometric/health/financial)? → on-device
Must work offline? → on-device
Model fits (<500MB vision, <2GB LLM)? → on-device feasible
Control release cadence? → if your app, easy model swaps

3+ "yes" → on-device. 5/5 → mandatory. All "no" → cloud.

Plan for the floor, not the flagship

A model that meets 50ms on Snapdragon 8 Elite Gen 5 can take several times longer on a CPU-only phone. Test on real target hardware, not just emulator.
