Hacker News·high signal

Google's AI Edge Gallery app, which runs Gemma 4 models entirely on-device with no internet required, has climbed to #8 among top downloaded productivity apps on Apple's App Store. The E2B and E4B edge models run in under 1.5GB of memory with 'Thinking Mode' and 'Agent Skills' for offline reasoning and agentic workflows. The 752-point, 210-comment HN thread signals massive practitioner interest in on-device AI that eliminates API costs, rate limits, and data privacy concerns.
