The Android app, briefly published on Google's main Play Store account, was a 1.13GB download from Google Research using a local Gemini Nano model.
COSMO offered a basic chat interface plus tools including document writing, calendar suggestions, web search, deep research, recall and conversation summaries, while requesting several system permissions.
The listing described on-device AI for everyday tasks and included Hybrid, PI Only and Nano Only modes, suggesting a test bed for future products ahead of Google I/O 2026.
