Shipping an Edge-AI App

The demo runs on your phone; now you have to get it running on thousands of phones you'll never touch. Shipping on-device AI has its own hard problems — a model file too big to bundle, first-run downloads, a fleet of wildly different devices, and updates you can't push instantly — and handling them is what separates a hackathon project from a product.

Privacy and Local-First Design

On-device AI's biggest promise is privacy — but that promise is only real if the architecture actually keeps data on the device. Privacy isn't a feature you add; it's a property of a design where sensitive data has no path off the phone. This post is about building that property in deliberately, and about the honest hybrid designs for when pure local isn't enough.

On-Device RAG and Memory

An on-device model only knows what's baked into its weights — nothing about the user's notes, messages, or documents. On-device RAG fixes that by doing retrieval entirely on the phone: embed the user's data locally, store the vectors locally, and retrieve locally, so the model can reason over personal data that never touches a server. It's the technique that makes a private assistant actually useful.

Gemma on Flutter

This is where the concepts become code. With a quantized Gemma model and the flutter_gemma plugin, running a real LLM entirely on the user's phone is a handful of Dart calls — load the model, open a chat session, stream tokens into your UI. The plugin hides the runtime; you write an app.

The On-Device Runtime

Between your quantized model file and a running feature sits the runtime — the engine that loads the model, maps it onto the phone's CPU, GPU, or NPU, and turns tokens into text. You rarely write inference math yourself; you pick a runtime and let it handle the brutal complexity of executing a neural network across thousands of different devices.

Making Models Fit: Quantization for the Edge

On the cloud, quantization is an optimization you reach for to cut costs. On a phone, it's the difference between the model running and not running at all. Nearly every on-device LLM you'll ever ship is quantized, because full-precision weights simply don't fit — so understanding the bit-width trade-off is non-negotiable for edge AI.

The Constraints of the Edge

A phone is not a small server — it's a fundamentally different environment with four hard limits a data center never imposes: a tight memory budget, modest and heterogeneous compute, a battery that your model drains, and a thermal ceiling that throttles you when you push it. Every on-device AI decision is a negotiation with these four.

Why On-Device AI?

For a decade the default answer to "where does the AI run?" was "someone else's GPU, over the network." On-device AI flips that: the model runs on the phone in the user's hand, and once you internalize what that changes — privacy, offline capability, latency, and cost all at once — a whole class of apps becomes possible that a cloud API can't build.
