Slash commands
Ce contenu n’est pas encore disponible dans votre langue.
Brain works fine in plain English. Slash commands are for cases where you want explicit control: change the underlying LLM, see what’s available, get help.
Help & discovery
Section titled “Help & discovery”| Command | What it does |
|---|---|
/help | List every command + a one-line description. |
/provider list | Show every provider (Gemini, OpenAI, Mistral, Claude) + the model id at each tier (small / medium / large). |
/model list | Same matrix, grouped by tier × provider. |
Switch provider (persistent)
Section titled “Switch provider (persistent)”/provider sets the LLM that handles all your turns going forward, until you change it again.
| Command | Effect |
|---|---|
/provider | Show current provider. |
/provider gemini | Use Google Gemini. |
/provider openai | Use OpenAI (GPT). |
/provider mistral | Use Mistral. |
/provider claude | Use Anthropic Claude. |
/provider reset | Back to default (Gemini). |
Natural language works too: “use mistral as provider”, “switch to claude”.
Switch tier (persistent)
Section titled “Switch tier (persistent)”/model sets the size/cost tier within whichever provider is active.
| Command | Effect |
|---|---|
/model small | Cheapest, fastest. |
/model medium | Balanced (default). |
/model large | Most capable. |
/model reset | Back to default. |
Natural language: “use the small model”, “utilise le modèle large”.
Per-turn override (one-shot)
Section titled “Per-turn override (one-shot)”Prefix a message with a provider or tier name to use it for this turn only — your persistent settings stay untouched.

|---|---|
