# API keys (hub)

> Hosted API keys vs editor BYOK keys.

V3Code is [BYOK](/models/byok)-friendly. Add your model provider keys in Settings and V3Code uses them directly.

## Where keys live

Your keys are stored **locally** on your machine, not on a server. Only the model calls you make use them, going straight to the provider you're calling.

## Which keys you might add

* **Anthropic** — required for the free [auto router](/models/overview).
* **Any other provider** you want to run yourself instead of using hosted credits.
* **Local models** need no key at all — see [Run models locally](/models/byok).
