This tutorial walks through Google AI Edge Gallery on Android and iOS, covering model downloads and on-device chat. The presenter describes it as a private way to run models locally and shows how to switch models after initialization.
Hardware advice centers on memory: the speaker recommends 8 GB of RAM or more for Gemma 4 on recent Android phones, an iPhone 15 Pro or newer, or an M-series iPad with 8 to 16 GB. Older phones with 4 to 6 GB are described as better suited to the smaller Gemma 3 1B model. These are the presenter's recommendations, rather than tested compatibility guarantees.
The settings walkthrough covers thinking, temperature, top K and top P. The speaker recommends GPU execution, though the tutorial does not establish that it is faster on every device. A practical limitation is that the demonstrated app retains text input history rather than full conversations.
Agent Skills provide instructions for specific tasks and can be imported from a URL or a local file. The image section shows questions about photos and discusses offline use. Audio Scribe accepts recordings or WAV files; the presenter advises adding a text prompt and resetting the conversation before another clip. Experimental Mobile Actions receives flashlight commands, with a warning that actions may not always work. Prompts Lab supplies presets for summarizing text and rewriting its tone.
