AI generated summary, Read the full article for complete information.
Google unintentionally released its experimental on‑device AI assistant, COSMO, to the Play Store on May 1, 2026, only to pull it within hours. The 1.13 GB app, built by Google Research, runs a local Gemini Nano model and offers three inference modes—offline Nano, server‑side “PI” (Personal Intelligence), and a hybrid that switches based on connectivity. COSMO bundles 14 AI‑powered “Skills,” including a List Tracker, Calendar Event Suggester, a Browser Agent powered by Google’s Mariner web‑automation tool, a Deep Research mode for multi‑source reports, and a Conversation Summary feature, though not all skills are enabled by default. Its Play Store listing described it as “an experimental AI assistant application for Android devices,” and the hurried, partially mis‑scaled screenshots suggest the release was a premature glimpse of what Google plans to unveil at I/O 2026 beginning May 19.
