Open Viro

    AI Models

    Viro includes five AI models: Viro AI, ChatGPT, Gemini, Claude, and Apple Intelligence. Viro AI is the default, you can switch models at any point in a conversation, and every model is available on every plan, including Free. Apple Intelligence runs on your own device, so it's only usable on recent iPhones, iPads, and Macs.

    To see this in the app, open the model menu in the message box and select About our AI models. For what the energy labels mean, see Energy & Impact.

    Viro AI routes each request to a model sized for it: small, efficient models for simple questions and larger models for complex tasks. That keeps replies fast and cuts the energy each one uses.

    How do I switch models?

    1. In the message box, open the model menu. It shows the name of the model you're using.
    2. Choose Viro AI, ChatGPT, Gemini, Claude, or Apple Intelligence. Apple Intelligence is greyed out on devices that can't run it.
    3. Send your message. The model you chose answers from that point on, with the conversation so far as context.

    A switch lasts for the current session. New chats, and older chats you reopen, start with your default model.

    How do I change my default model?

    1. Select your email at the bottom of the sidebar, then Settings.
    2. Under Account, select Default AI Model.
    3. Choose the model you want new chats to start with.

    Your default is saved to your account, so it applies on the web and in the apps.

    Things to know

    • Different models give different answers, writing styles, and levels of detail. If an answer misses, switch models and ask again.
    • The same usage limits apply whichever model you use. Apple Intelligence runs on your device, so its chats don't count toward them.
    • Apple Intelligence handles text on your device and can search the web and use your calendar, files, and connected apps; image creation uses the other models.

    AI models can make mistakes.

    Double-check important information, especially for medical, legal, financial, or other high-stakes decisions.

    Frequently asked questions

    Can I use ChatGPT, Claude, and Gemini on the free plan?

    Yes. All four models (Viro AI, ChatGPT, Gemini, and Claude) are available on every plan, including Free.

    Does Viro remember which model I picked?

    Your default model is saved to your account. If you switch models inside a chat, that choice lasts for the current session, and new chats start with your default.
