219219Cloud sessions support [built-in commands](/docs/en/commands) that produce text output. Commands that only run in the terminal interface, such as `/plugin` or `/resume`, aren't available. Commands that open a picker or panel in the terminal behave differently in cloud sessions:

221* **`/model`, `/effort`, `/color`, and `/rename`**: pass the value as an argument, for example `/model sonnet`, instead of opening the terminal picker or slider. The argument forms require Claude Code v2.1.205 or later in the session's environment and follow each command's [availability notes](/docs/en/commands#all-commands): `/effort` reports `Not applied` while a model's [launch-default effort hold](/docs/en/model-config#adjust-effort-level) is in force.
221* **`/model`, `/effort`, `/color`, and `/rename`**: pass the value as an argument, for example `/model sonnet`, instead of opening the terminal picker or slider. The argument forms require Claude Code v2.1.205 or later in the session's environment and follow each command's [availability notes](/docs/en/commands#all-commands).
222222* **`/fast`**: toggles [fast mode](/docs/en/fast-mode#use-fast-mode-in-cloud-sessions) for the session when fast mode is [available on your account](/docs/en/fast-mode#requirements). Requires Claude Code v2.1.271 or later in the session's environment.
223223* **`/config`**: in your browser at claude.ai/code, opens the Claude Code section of your settings instead of setting a value, and text after the command, including `key=value`, is ignored. To change a setting for a cloud session, set an [environment variable](/docs/en/cloud-environments#set-environment-variables) on the environment, or in a session with one repository, commit the key to that repository's `.claude/settings.json`. [Settings in cloud sessions](/docs/en/settings#settings-in-cloud-sessions) lists what each session reads.
