Android AICore lets you “run generative AI features directly on your Android phone or tablet’s hardware.” These models (Gemini Nano) are inherently large, but Google now has a more detailed explanation of why Android AICore storage occasionally spikes.
AICore is available on Android 14 and higher for supported devices (processors). Google provides a list of which features and apps use the local model:
- Advanced proofreading: It enhances grammar correction and language understanding as you type.
- Automatic Speech Recognition (ASR): It converts streamed audio and audio files into text transcripts.

- Translation: It easily translates text from one language to another.


More broadly, on-device AI is credited as allowing for enhanced privacy, offline functionality, and faster and more consistent performance:
- “Sensitive information remains on your device. It’s never sent to the cloud or to Google.”
- “AI-powered features work even when you have no network connection or are in Airplane mode. This includes text summarization and smart replies.”
- “Local processing removes the lag associated with cloud-based services providing a faster and more reliable experience.”
A Google support article now explains “Why storage use increases.” When a new version of Gemini Nano is available, AICore “temporarily keeps both the old and new versions of the model for up to 3 days.”
This is intended as a “fail-safe [that] allows your phone to instantly revert to an…
