Controller Cloud Provider - FREE AI Models

Access FREE AI models through Controller Cloud authentication, including "grok-code-fast-1" (formerly "roo/sonic") and the new "code-supernova" model. No API keys, no credit cards, no usage costs during the promotional period.

Model Name Update

The "roo/sonic" model is being renamed to "grok-code-fast-1" (officially "Grok Code Fast"). The model will be updated by August 29th. This is the same powerful coding model, just with its official xAI name. The model remains free when accessed through Controller Cloud during the promotional period.

Important for Controller users: Within Controller, this model is only free through Controller Cloud. Using it directly through the xAI provider in Controller will incur standard charges once pricing is established.
