Arc
Optional access to open-weight models hosted on European infrastructure.
Arc is Radian's optional model-access service for open-weight models hosted on European infrastructure. It is intended to work with Radian and other compatible coding agents.
Intended role
- Provide a straightforward endpoint for supported open-weight models.
- Offer subscription tiers beginning at the pricing published on the Arc page.
- Keep model access separate from the desktop, so bringing another provider remains possible.
Arc is not required to use Radian. You can continue to bring supported subscriptions and API keys directly.
Operational limits, exact model availability, retention behavior, and client configuration will be documented before public availability. See the Arc product page for the current commercial description.
