Run Gemma 4 AI models locally on Android and iPhone

Google now offers official tools for running Gemma 4 AI models locally on Android and iPhone devices. Users can access Gemma 4 through the AI Edge Gallery app for testing or LiteRT-LM for app development, with smaller models like E2B recommended for initial use. The process involves downloading the AI Edge Gallery app, selecting a Gemma 4 model, and initiating a chat, though device RAM requirements and model performance variations should be considered.
