Sol is available to Copilot Pro+, Max, Business, and Enterprise plans, while Terra and Luna extend to Pro plans as well. Models are selectable via the model picker across VS Code, JetBrains, Xcode, Eclipse, GitHub Mobile, and other surfaces. Enterprise and Business admins must manually enable the policy in Copilot settings, as it is off by default. Billing follows provider list pricing under Usage Based Billing. ## Full article daily.dev links to this article rather than hosting it.
