Gemini CLI Model Selection (`/model` Command)

Select your Gemini CLI model. The /model command opens a dialog where you can configure the model used by Gemini CLI, giving you more control over your results.

How to use the /model command

Use the following command in Gemini CLI:

/model

Running this command will open a dialog with your model options:

• Auto (recommended): Let the system choose the best model for your task. Typically, this is the best option.
• Pro: For complex tasks that require deep reasoning and creativity. The Pro model may take longer to return a response.
• Flash: For tasks that need a balance of speed and reasoning. The Flash model will usually return a faster response than Pro.
• Flash-Lite: For simple tasks that need to be done quickly. The Flash-Lite model is typically the fastest.

Changes to these settings will be applied to all subsequent interactions with Gemini CLI.

Best practices for model selection

• Default to Auto (recommended). For most users, the Auto (recommended) model provides a balance between speed and performance, automatically selecting the correct model based on the complexity of the task. Example: Developing a web application could include a mix of complex tasks (building architecture and scaffolding the project) and simple tasks (generating CSS).

• Switch to Pro if you aren’t getting the results you want. If you think you need your model to be a little “smarter,” use Pro. Pro will provide you with the highest levels of reasoning and creativity. Example: A complex or multi-stage debugging task.

• Switch to Flash or Flash-Lite if you need faster results. If you need a simple response quickly, Flash or Flash-Lite is the best option. Example: Converting a JSON object to a YAML string.
