Agent modes let you control the balance between speed, cost, and capability when using Agent. Use the top-level mode selector in the Agent settings dropdown to switch between Lite, Economy, and Power. Expand Advanced settings when you want more control over testing, code review, and Turbo.

Keyboard shortcut: Press ⌘+Shift+I (Ctrl+Shift+I on Windows) to cycle through Agent modes without leaving the chat input.
Max mode is no longer available. Use Power for the most capable standard builds, and turn on Turbo in Advanced settings when you need the fastest runs.

Lite mode

Optimized for quick edits. Lite uses fast, lightweight models for visual tweaks, bug fixes, and other small, scoped changes.
Agent modes dropdown with Lite selected
Best for: Quick fixes, UI polish, and short iteration loops while you stay at your keyboard. Keep in mind: Lite works best in existing apps when you already know what you want to change. If you’re starting from scratch, making large architectural changes, adding a new integration, or changing a database schema, switch to Economy or Power. Cost: Lite uses the same effort-based pricing model as the other build modes, but focused requests often cost less than Economy or Power for the same targeted edit.

Economy mode

Optimized for cost. Economy uses fewer credits per task and is the best default when you want strong results without paying for the most capable models.
Agent modes dropdown with Economy selected and Advanced settings expanded
Best for: Everyday builds, learning, and cost-conscious work across an existing project.

Power mode

Optimized for capability. Power uses more capable models for complex tasks, larger codebases, and harder problems.

Best for: Production-grade projects, complex features, and when you want the best results from Agent.

Power mode suggestions

When you are in Economy mode and Agent notices you are hitting the same problem repeatedly, it suggests switching to Power mode for your next message. You will see the suggestion at most once per project. Once you dismiss it or act on it, Agent will not nudge you again in that project, even if you stay in Economy.

Advanced settings

Expand Advanced settings in the dropdown to manage the rest of Agent’s build controls:
  • App Testing lets Agent test your app automatically in a browser.
  • Code Optimizations lets Agent review and improve its own code as it works.
  • Turbo gives you the fastest available models when you’re in Power mode.
Lite keeps App Testing and Code Optimizations off, and Turbo is only available while Power is selected.

Turbo mode

Turbo is a separate toggle inside Advanced settings. Turn it on in Power mode when you want 2.5x faster responses using the fastest models. Requests can cost up to 6x more than Power, so Turbo is best when speed matters more than efficiency.

Turbo is highlighted in orange in the Agent modes dropdown as a visual reminder that it costs significantly more than Power. Keep an eye on the highlight when you’re iterating quickly — it’s there to keep the cost tradeoff visible.
Availability: Pro and Enterprise only. Best for: When you need the fastest possible Agent response and are on a Pro or Enterprise plan.

Which mode should I use?

Balance cost and quality for most projectsPower

You can change modes at any time from the Agent settings dropdown in the chat input. Choose Lite, Economy, or Power from the top-level control, then expand Advanced settings when you want more control over testing, code review, or Turbo. No single mode is always best—pick the one that fits the task in front of you.

Settings in shared projects

Your Agent settings are tied to you, not to the project. When you invite a teammate into a project, each of you keeps your own choices for:
  • Mode (Lite, Economy, or Power)
  • Plan Mode
  • Auto-merge for background tasks
  • Auto-approve for plans
  • Turbo
A teammate switching to Power on their next task does not flip your settings to Power. The mode and toggles you see in the Agent settings dropdown are the ones Agent uses when you send the next message, regardless of how many collaborators are in the project.
