Agent Modes

Agent modes let you control the balance between cost and capability when using Agent. Use the Agent settings dropdown to choose Free Mode, Power Mode, or Max Mode. Free Mode always uses intelligent model routing. In Power or Max, Core and Pro builders can select Auto to let Replit choose a model for each task. They can also use the Model selector to choose a model manually. The modes and settings you see depend on your plan and workspace.

​

Free Mode

Optimized for getting started. Free Mode helps you explore ideas, learn how Replit works, and begin a project. Keep in mind: Free Mode always uses intelligent model routing. To select a model manually, use Power Mode or Max Mode. Routines do not run in Free Mode. They run in Power or Max Mode and require a per-run budget. Learn more about Routines.

​

Intelligent model routing (Auto)

Optimized for automatic model selection. In Power Mode or Max Mode, Core and Pro builders can select Auto. Replit then chooses a model up to the selected mode’s capability for each task. See Use intelligent model routing. Auto is a paid alternative to Free Mode. It uses subscription credits like other Power and Max work. Enterprise workspaces use one Auto mode instead of Free Mode. Enterprise Auto can choose both the mode and an allowed model for each task.

​

Power Mode

Optimized for cost. Power Mode uses fewer credits per task and is the best default when you want strong results without paying for the most capable models. Best for: Everyday builds, learning, and cost-conscious work across an existing project.

​

Max Mode

Optimized for capability. Max Mode 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.

​

Which mode should I use?

Use the following as a guide: Use the Agent settings dropdown in the chat input to pick a mode. In Power or Max, Core and Pro builders can use Auto or set a primary model and Effort. No single mode is always best. Pick the mode 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 (Free Mode, Power Mode, or Max Mode)
• Primary model and Effort, when available
• Plan Mode
• Auto-merge for background tasks
• Auto-approve for plans

A teammate switching to Max Mode on their next task does not flip your settings to Max Mode. The mode and settings 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.
