on-device AI
AI models running locally on consumer devices, reducing the need for cloud-based processing.

When to use it
Use on-device AI when cloud-based processing introduces latency or privacy concerns. On-device AI models bring computation directly to consumer devices, enabling real-time applications like MIDI piano autocompletion without relying on remote servers.
Quick example
In Apple's iPhone, a 125M-parameter transformer model runs directly on the device to autocomplete piano performances in real time. This is on-device AI: the model processes MIDI data locally, eliminating the need for cloud interaction and ensuring user privacy. Apple's implementation shows how on-device AI can deliver high-performance AI applications without external dependencies.
Ecosystem
On-device AI interacts with local hardware and software, minimizing cloud dependency and enhancing user privacy.

Misconceptions
| Misconception | Rebuttal |
|---|---|
| On-device AI needs the internet | It runs entirely on local hardware |
| It's less powerful than cloud AI | Advances in hardware allow competitive performance |
Trade-offs
- Privacy — limited by local hardware capabilities
- Latency — reduced at the cost of device battery life
- Accessibility — hardware-specific optimizations required
