Google AI Edge Gallery: offline phone chat setup

This tutorial explains how to download a model in Google AI Edge Gallery and use it for offline chat on a phone. The speaker describes installation through Google Play or Apple's App Store and says the procedure supports Android and iPhone. The demonstration uses a phone with Wi-Fi disabled and no SIM access; it does not separately demonstrate both platforms.

The setup starts in the Chat section, where users select a model to download. The speaker recommends checking model sizes against the phone's capabilities, warning that a demanding model may freeze or run slowly. He uses a model identified in the transcript as "Gema 4 E2 2B," with a stated download size of 2.5 GB. The app displays a memory compatibility warning, but he proceeds and submits prompts in airplane mode.

The examples ask about Mexico and solve an equation. A question about Mexico's president exposes a limitation: the model requests a date and gives unhelpful follow-up responses. The speaker says its information goes up to 2025, though the exchange does not establish a reliable knowledge cutoff. He also warns that the phone may get warm while running a model.

The final section briefly opens skill agents, with examples such as map interaction and a hash calculator. These options receive a short tour rather than a working demonstration. The speaker describes the app as free; his suggestion of unlimited use is not tested.
