Distributing big AI models in mobile apps
summary
SwiftKey is a billion‑download keyboard that keeps the APK small (20 MB download / 55 MB installed) while adding AI by choosing between cloud and on‑device models. Generative features like sticker and image generation run in the cloud (uses Deli 3), trading latency and cost for unlimited model size and easy updates. Language packs live on a server and download at runtime to avoid bloating installs — there are 700 languages with packs of 2–20 MB, managed per‑user and updated separately.
