# 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.
