GitHub Copilot CLI now offers slash commands that let you control AI model selection, manage token usage, resume past work sessions, and inspect code changes—all from the terminal.

What happened: GitHub Copilot CLI includes built-in slash commands accessible from the command line that let you guide Copilot's behavior, inspect changes, manage context, move across sessions and projects, and keep permissions tidy. Key commands include /model to switch between models, /context to check token usage, /compact to summarize conversations and free space, /resume to pick up previous sessions, /diff to view recent code modifications, /cwd to change working directories across repositories, and /reset-allowed-tools to reset permissions.

Why it matters: Slash commands give you control over which AI model you use based on your task—some models handle quick refactoring while others manage deeper reasoning—and let you manage how much information Copilot remembers during a session. This means you can stay efficient in your terminal without switching tools or losing track of your work across multiple projects.

What to watch: You can explore all available slash commands by typing / in the command line for a scrollable list. The /model command shows key details like capabilities, availability depending on your plan or organization's settings, and cost multipliers to help you balance performance and usage.
