# On-device AI

> On-device AI is a web app that runs a small language model entirely in the visitor's browser — no server, no API key, no account. This card describes the agent-facing surface: documentation, skills, and pages an agent can read or guide a user through. There is no programmatic API and no agent message endpoint.

## Skills
- **Chat with the on-device model** — Walk a user through chatting with the on-device model: pre-flight device check, model choice, one-time download, then offline-capable chat.
- **Compare the models** — Compare the available models (Qwen2.5 0.5B/1.5B, Llama 3.2 1B, Phi-4 mini, SmolLM2 360M) by download size and speed trade-offs.
- **Diagnose the device** — Use the diagnostics page to name the visitor's browser, OS, and graphics chip and give per-device performance tips.
