# The on-device AI model, opt-in

> The on-device AI model is a private, local AI for your Mac — a small language model that runs entirely on this Mac, downloaded only if you choose to add it.

**Where in FireAI:** Home › Ask FireAI, "Add AI"

Get plain-language understanding and AI summaries that never leave your Mac once downloaded.

Without it, Ask FireAI already understands simple, direct orders. Click “Add AI” and FireAI downloads a small on-device model (about 1.5 GB, stays on this Mac) once from Hugging Face, so it can also work out orders phrased less directly, or names it doesn’t already recognise. See [Ask FireAI](https://hisnlabs.com/fireai/en/docs/ask-fireai) for what it understands even without this model.

- It runs on this Mac’s own GPU. FireAI shows its status as it downloads, loads, and once it’s ready: “AI ready · runs only on this Mac”.
- It’s also what writes the plain-language summaries you can ask for in Investigate, always restricted to the facts FireAI has already gathered.
- On an Intel Mac, the same model runs through the free Ollama app instead, and FireAI guides you through the setup: see [Use FireAI’s AI on an Intel Mac with Ollama](https://hisnlabs.com/fireai/en/docs/ai-on-intel-mac-with-ollama).

> **Note:** This is a separate system from FireAI Pilot’s own decision model: this one turns language into an order or a summary; FireAI Pilot’s model only decides allow, deny or ask for a connection and never generates text. Turning this on doesn’t turn FireAI Pilot on, and FireAI Pilot works without it.

> **Warning:** Written summaries can be wrong. FireAI says so next to every one it writes, and points to the underlying facts so you can check them yourself.
