Billing and administrator controls
Under usage-based billing, Gemini 4 Argon is billed at provider list pricing. The announcement does not give numeric token rates.
Business and Enterprise administrators can manage access through the model policy in Copilot settings. Under default model enablement, new models are automatically enabled unless an administrator has turned off the global default or explicitly disables this model.
