Everyday Quick Edits: Use the free Velox II model for instant answers and small code changes in the terminal.
Deep Reasoning Tasks: Escalate to Faber II on Pro for complex coding and multi-step reasoning.
Mobile Task Steering: Kick off a refactor at your desk and monitor or redirect it from your phone.
