Google launches experimental COSMO AI assistant on Play Store
▼ Summary
– Google accidentally published COSMO, an experimental AI assistant app for Android, then removed it from the Play Store.
– The app uses a local Gemini Nano model, resulting in a 1.13 GB download, and features a basic chat interface.
– COSMO has skills such as creating lists, scheduling calendar events, summarizing conversations, and performing deep research.
– It offers three fulfillment model options: Hybrid (online and offline), PI Only (server-based), and Nano Only (local).
– The release appears premature, likely intended as a test bed for future experiences before Google I/O 2026.
Yesterday, Google quietly published “COSMO,” an experimental AI assistant for Android, on the Play Store. The app has since been pulled, confirming it was an accidental release.
The application originates from Google Research, with the package name com.google.research.air.cosmo, but it was distributed through the company’s main Play Store account. The listing described COSMO as bringing “the power of artificial intelligence directly onto your device” to handle tasks from organizing your day to answering complex questions.
Weighing in at 1.13 GB, the app includes a local Gemini Nano model. After installation, it requests several system permissions and presents a basic chat interface that underscores its experimental nature. COSMO appears to be a test bed for future features rather than a consumer-ready product.
The app lists a range of “Skills” or capabilities:
- List Tracker: Automatically suggests keep lists.In the settings, a “Fulfillment Model” menu offers three options: Hybrid (PI when online, Nano offline), PI Only (server-based), and Nano Only (local only). What “PI” stands for remains unclear, but the local model is likely Gemini Nano.Additional features include voice match setup and screen access permissions.This appears to be a premature or accidental release ahead of Google I/O 2026, which takes place later this month. The app is clearly not intended for general consumers.
