Gemma 4 on the iPhone (local AI, no internet required)

Google's Gemma 4 open-source AI models can now run entirely on-device via the AI Edge Gallery app, with no internet connection required. The demo showcases the 2B and 4B parameter models running on an iPhone in airplane mode, handling text queries, image recognition, and audio input at impressive speeds. A separate mobile actions model can even control phone functions like the flashlight via voice commands, highlighting the growing potential of edge AI computing.
